CHEMICAL COMPATIBILITY GUIDE

Attached you will find 2 charts: 1 from Nibco and 1 from FMC Technologies

Also go to our website for the best valve materials chemical compatibility chart: -

www.globalsupplyline.com.au/pdfs/catalogues/gsl/Valve_chemical_resistance.pdf

These Chemical Compatibility Charts are indicative only. You will find a wide variation between

different valve material corrosion charts. Other than our own chart, these are the best two charts

we could find and their benefit is that they specifically relate to body and trim materials used in

valve construction and they cover some material types and media types not listed in our chart.

Go to the Technical section of our website for another chart on other valve body & trim material

chemical composition characteristics. You will find there is a wide degree of variation between

different charts so it pays to cross check a few charts.

If we dont have the valve in stock we can source it from our overseas network of stockists and

very short lead-time specialty manufacturers. We can even supply exotic grades like Nickel,

Super Duplex F55 and Monel (ASTM A494-M35-1) Cd4M-Cu, Hastelloy C (ASTM A-494

CW12MW), 317 (C8G8M) in short lead-time.

We stock valves in A105, LF2, 304, 304L, 316, 316L, F51, CF8, CF3, CF8M, WC5, WC6, WC9,F11, F22, F5, Bronze, Iron, etc. in Ball, Butterfly, Check, Control, Gate, Globe, Needle, Parallel

slide, Plug, etc. Valves are manufactured to API600, API602, API603, API6A, API6D, BS1868

and numerous other standards

We put the same level of care and attention to detail that went into this website into every facet

of our business. If you found this website helpful, recommend us to your plant managers,

engineers and purchasing staff!

INTRODUCTION

This Chemical Resistance Guide has been compiled to assist the

piping system designer in selecting chemical-resistant materials.

The information given is intended as a guide only. Many condi-

tions can affect the material choices. Careful consideration must

be given to temperature, pressure and chemical concentrations

before a final material can be selected.

The physical characteristics of thermoplastics and elastomers

are more sensitive to temperature than metals. For this reason, a

rating chart has been developed for each.

MATERIAL RATINGS

FOR THERMOPLASTICS & ELASTOMERS

Temp. in F = A rating, maximum temperature

which is recommended, resistant

under normal conditions

B to Temp. in F = Conditional resistance, consult factory

C = Not recommended

Blank = No data available

MATERIAL RATINGS FOR METALS

A = Recommended, resistant under normal

conditions

B = Conditional, consult factory

C = Not recommended

Blank = No data available

Temperature maximums for thermoplastics, elastomers andmetals should always fall within published temp/pressure ratings

for individual valves. THERMOPLASTICS ARE NOT RECOM-

MENDED FOR COMPRESSED AIR OR GAS SERVICE.*

This guide considers the resistance of the total valve assembly

as well as the resistance of individual trim and fitting materials.

The rating assigned to the valve body plus trim combinations

is always that of the least resistant part. In the cases where the

valve body is the least resistant, there may be conditions under

which the rate of corrosion is slow enough and the mass of the

body large enough to be usable for a period of time. Such use

should always be determined by test before installation of the

component in a piping system.

In the selection of a butterfly valve for use with a particularchemical, the liner, disc, and stem must be resistant. All three

materials should carry a rating of A. The body of a properly

functioning butterfly valve is isolated from the chemicals being

handled and need not carry the same rating.

THERMOPLASTICS & ELASTOMERS

ABS Acrylonitrile Butadiene Styrene Class 32222 conform-

ing to ASTM D3965 is a time-proven material. The smooth inner

surface and superior resistance to deposit formation makes ABS

drain, waste, and vent material ideal for residential and com-

mercial sanitary systems. The residential DWV system can be

exposed in service to a wide temperature span. ABS-DWV has

proven satisfactory for use from -40F to 180F. These temper-

ature variations can occur due to ambient temperature or thedischarge of hot liquids into the system. ABS-DWV is very resis-

tant to a wide variety of materials ranging from sewage to com-

mercial household chemical formulations. ABS-DWV is joined by

solvent cementing or threading and can easily be connected to

steel, copper, or cast iron through the use of transition fittings.

CPVC Chlorinated Polyvinyl Chloride Class 23447 conform-

ing to ASTM D1784, has physical properties at 73F similar to

those of PVC, and its chemical resistance is similar to or gener-

ally better than that of PVC. CPVC, with a design stress of 2000

psi and maximum service temperature of 210F, has proven to

be an excellent material for hot corrosive liquids, hot or cold wa-

ter distribution, and similar applications above the temperature

range of PVC. CPVC is joined by solvent cementing, threadingor flanging.

PP (Polypropylene) Polypropylene is a polyolefin, which is

lightweight and generally high in chemical resistance. Although

polypropylene is slightly lower in physical properties compared

to PVC, it is chemically resistant to organic solvents as well as

acids and alkalies. Generally, polypropylene should not be

used in contact with strong oxidizing acids, chlorinated hy-

drocarbons, and aromatics. With a design stress of 1000 psi

at 73 F, polypropylene has gained wide acceptance where its

resistance to sulfur-bearing compounds is particularly useful

in salt water disposal lines, crude oil piping, and low pressure

gas gathering systems. Polypropylene has also proved to be an

excellent material for laboratory and industrial drainage wheremixtures of acids, bases, and solvents are involved. Polypropyl-

ene is joined by the heat fusion process, threading or flanging.

At 180F, or when threaded, PP should be used for drainage

only at a pressure not exceeding 20 psi.

PVC Polyvinyl Chloride Class 12454 conforming to ASTM

D1784. PVC is the most frequently specified of all thermoplas-

tic materials. It has been used successfully for over 40 years

in such areas as chemical processing, industrial plating, chilled

water distribution, deionized water lines, chemical drainage, and

irrigation systems. PVC is characterized by high physical prop-

erties and resistance to corrosion and chemical attack by acids,

alkalies, salt solutions, and many other chemicals. It is attacked,

however, by polar solvents such as ketones, some chlorinatedhydrocarbons and aromatics. The maximum service tempera-

ture of PVC is 140F. With a design stress of 2000 psi, PVC has

the highest long-term hydrostatic strength at 73F of any of the

major thermoplastics being used for piping systems. PVC is

joined by solvent cementing, threading, or flanging.

PVDF Polyvinylidene Fluoride is a strong, tough and abrasion-

resistant fluorocarbon material. It resists distortion and retains

most of its strength to 280F. It is chemically resistant to most

acids, bases, and organic solvents and is ideally suited for han-

dling wet or dry chlorine, bromine and other halogens. No other

solid thermoplastic piping components can approach the com-

bination of strength, chemical resistance and working tem-

peratures of PVDF. PVDF is joined by the heat fusion process,

threading or flanging.

EPDM EPDM is a terpolymer elastomer made from ethylene-

propylene diene monomer. EPDM has good abrasion and tear

resistance and offers excellent chemical resistance to a variety

of acids and alkalines. It is susceptible to attack by oils and is

not recommended for applications involving petroleum oils,

strong acids, or strong alkalines.It has good ozone resistance.

It is fairly good with ketones and alcohols and has an excellent

temperature range from -20F to 250F.

POLYCHLOROPRENE (CR) Polychloroprenes were one of

the first synthetic rubbers developed. Polychloroprene is an all-

purpose polymer with many desirable characteristics and fea-

tures high resiliency with low compression set, flame resistance,

and is animal and vegetable oil resistant. Polychloroprene is

principally recommended for food and beverage service. Gener-

ally, polychloroprene is not affected by moderate chemicals, fats,

greases, and many oils and solvents. Polychloroprene is at-

tacked by strong oxidizing acids, most chlorinated solvents,

esters, ketones, aromatic hydrocarbons, and hydraulic flu-

ids. Polychloroprene has a moderate temperature range of

-20F to 160F.

NITRILE (NBR) BUNA-N is a general purpose oil-resistant

polymer known as nitrile rubber. Nitrile is a copolymer of butadi-

ene and acrylonitrile and has a moderate temperature range of

20F to 180F. Nitrile has good solvent, oil, water, and hydrau-

lic fluid resistance. It displays good compression set, abrasion

resistance and tensile strength. Nitrile should not be used

in highly polar solvents such as acetone and methyl ethyl

ketone, nor should it be used in chlorinated hydrocarbons,

ozone or nitro hydrocarbons.

FLUOROCARBON (FKM) Fluorocarbon elastomers are in-

herently compatible with a broad spectrum of chemicals. Be-

cause of this extensive chemical compatibility, which spans

considerable concentration and temperature ranges, fluorocar-

bon elastomers have gained wide acceptance as a material of

construction for butterfly valve o-rings and seats. Fluorocarbon

elastomers can be used in most applications involving mineral

acids, salt solutions, chlorinated hydrocarbons, and petroleum

oils. They are particularly good in hydrocarbon service. Fluoro-

carbon elastomers have one of the broadest temperature ranges

of any of the elastomers, -20F to 300F; however, they are not

suited for steam service.

PTFE Polytetrafluoroethylene has outstanding resistance to

chemical attack by most chemicals and solvents. PTFE has a

temperature rating of -20F to 400F in valve applications. PTFE,

a self-lubricating compound, is used as a seat material in ball

valves.

GRAPHITE Graphite is the packing and seal

material of choice for most fire-rated products, primarily

because of its high temperature rating of approximately 2000F.

Graphite has excellent chemical resistance, can retain com-

pressibility at all temperatures and has a low coefficient of fric-

tion. Graphite is not recommended for use in strong oxidizingatmospheres.

METALS USED IN VALVES & FITTINGS

COPPER Among the most important properties of wrot cop-

per materials are their thermal and electrical conductivity, corro-

sion resistance, wear resistance, and ductility. Wrot copper per-

forms well in high temperature applications and is easily joined by

soldering or brazing. Wrot copper is exclusively used for fittings.

BRONZE One of the first alloys developed in the bronze age

is generally accepted as the industry standard for pressure-rated

bronze valves and fittings. Bronze has a higher strength than

pure copper, is easily cast, has improved machinability, and is

very easily joined by soldering or brazing. Bronze is very resis-tant to pitting corrosion, with general resistance to most chemi-

cals less than that of pure copper.

SILICONE BRONZE Silicone bronze has the ductility of

copper but much more strength. The corrosion resistance of

silicon bronze is equal to or greater than that of copper. Com-

monly used as stem material in pressure-rated valves, silicon

bronze has greater resistance to stress corrosion cracking than

common brasses.

ALUMINUM BRONZE The most widely accepted disc mate-

rial used in butterfly valves, aluminum bronze is heat treatable

and has the strength of steel. Formation of an aluminum oxide

layer on exposed surfaces makes this metal very corrosion resis-

tant. Not recommended for high pH wet systems.

BRASS Generally, brass has good corrosion resistance. Sus-

ceptible to de-zincification in specific applications; excel-

lent machinability. Primary uses for wrot brass are for ball valve

stems and balls, and iron valve stems. A forging grade of brass

is used in ball valve bodies and end pieces.

GRAY IRON An alloy of iron, carbon and silicon, gray iron

is easily cast, and has good pressure tightness in the as-cast

condition. Gray iron has excellent dampening properties and is

easily machined. It is standard material for bodies and bonnets

of Class 125 and 250 iron body valves. Gray iron has corrosion

resistance that is better than steel in certain environments.

DUCTILE IRON Ductile iron has composition similar to gray

iron. Special treatment modifies metallurgical structure, which

yields higher mechanical properties; some grades are heat-treat-

ed to improve ductility. Ductile iron has the strength properties of

steel using similar casting techniques to that of gray iron.

CARBON STEEL Carbon steel has very good mechanical

properties and is resistant to stress corrosion and sulfides. Car-

bon steel has high and low temperature strength, is very tough

and has excellent fatigue strength. Mainly used in gate, globe,

and check valves for applications up to 850F, and in one-, two-,

and three-piece ball valves.

FOR LISTED VALVE METALS

3% NICKEL IRON 3% Nickel iron has improved corrosion

resistance over gray and ductile iron. Higher temperature cor-

rosion resistance and mechanical properties. Very resistant to

oxidizing atmospheres.

NICKEL-PLATED DUCTILE IRON Nickel coatings have re-

ceived wide acceptance for use in chemical processing. These

coatings have very high tensile strength, 50 to 225 ksi. To some

extent, the hardness of a material is indicative of its resistance to

abrasion and wear characteristics. Nickel plating is widely speci-

fied as a disc coating for butterfly valves.

400 SERIES STAINLESS STEEL An alloy of iron, carbon, and

chromium, 400 series stainless steel is normally magnetic due to

its martensitic structure and iron content. It is resistant to high

temperature oxidation and has improved physical and mechani-

cal properties over carbon steel. Most 400 series stainless steels

are heat-treatable. The most common applications in valves are

for stem material in butterfly valves and backseat bushings and

wedges in cast steel valves.

316 STAINLESS STEEL An alloy of iron, carbon, nickel, and

chromium, 316 stainless steel is nonmagnetic with more ductility

than 400SS. Austinetic in structure, 316 stainless steel has very

good corrosion resistance to a wide range of environments, isnot susceptible to stress corrosion cracking and is not affected

by heat treatment. Most common uses in valves are stem, body

and ball materials.

630 STAINLESS STEEL 630 stainless steel is a martensitic

precipitation/age hardening stainless steel, offering high strength

and hardness. 630 SS withstands corrosive attack better than

any of the 400 series stainless steels, and in most conditions

its corrosion resistance closely approaches that of 300 series

stainless steel. 630 SS is primarily used as a stem material for

butterfly and ball valves.
