Thermal-Expanded Graphite Sealing GasketsSpecs 5728-006-93978201-2008 (agreed upon with OJSC VNIINeft-emash)

The gaskets are punched or cut from graphite sheet material (MGL), not reinforced or reinforced, or manufactured by two-side cladding of the metal core with graphite sheet material.

The gaskets can be assembled from closed-configuration segments in order to get single-piece or demountable gaskets.

The demountable gaskets are particularly accessible for assembling with-out complete disassembly of the unit to be sealed when repaired.

Gaskets can have partition bars of various shapes. The gaskets are designed to seal flange joints with smooth sealing sur-

faces, male-female and coak-groove surfaces, as well as to seal other joints (units), including threaded ones.

They are used in valves, pipelines, containers, apparatuses, pumps and analogous equipment in nuclear and thermal power, and in chemical, refining, gas, shipbuilding, aircraft and other industries.

Design and applications of gaskets are agreed upon with OJSC VNIINeft-emash.

Technical data of gaskets correspond to technical data of material they are made of.

Irregular shape GasketsSpecs 5728-006-93978201-2008

The irregular gaskets are manufactured with the use of LR-1600 plotter of ZUND company (Switzerland).

The main advantages of this method:cutting speed, 10 m/min;

accuracy, 0.1 mm;

decreasing time of preparation to work, and possibility to work right from the customer’s drawing;

flexibility of technology planning;

freedom in designing.

Strict compliance with the required technical parameters and sizes, and the possibility to manufacture gaskets of any irregular shape are attained by using KOMPAS-3D licensed program (three-dimensional modeling of parts and assembly units).

The range of gasket sizes is determined by sizes of the plotter table (1600x1800 mm) and material properties (not reinforced or reinforced graph-ite sheet material). Big-size gaskets are made of segments according to the special technology.

High-Temperature GasketsSpecs 5728-006-93978201-2008

Special design gaskets are meant for hermetic sealing of joints and connections of blast-furnace process equipment operating at a temperature up to 1400 oC.

Sealing Gaskets with Corrugated Metal Core Specs 5728-013-93978201-2008 (agreed upon with OJSC VNIINeftemash)

Metal based gaskets are intended for sealing of flange joints of valves, heat exchangers, pipelines, containers and other equipment used in nuclear and thermal power, and in chemical, petrochemical, refining, gas, metallurgy and other industries. Gaskets application and design are agreed upon with OJSC VNIINeft-emash. The gasket consists of the metal base of corrosion-resistant steel in the shape of valves cladded with not reinforced graphite material from both sides. The corrugated metal core adds extra flexibility, strength, capacity of relaxation and resistance to pressing-out. Resilience of gasket allow to keep sealability under repeated temperature differences.

Technical Data

big-size flanges (nominal diameter > 1000 mm);

flanges with increased deviation from planeness > 0.5 mm;

repeated temperature differences;

high pressure (nominal pressure > 10 MPa);

tough operating conditions.

The metal core makes it possible to fit the gasket with additional fastening elements which facilitate the gasket assembly on upright flanges.

Corrugated metal core gaskets

Graphitecomponent

Corrugatedmetal core

Design of corrugated based gasket

Unlike tooth-base gaskets clad with a thin not reinforced graphite sheet the corrugated metal core gaskets keep sealability at substantially big flange opening caused, for instance, by thermal expansion or loosened bolt tightness, and can com-pensate essential flange surface defects.

The gaskets can be round, square, right-angled or oval, and can have any types of partition bars. Gasket sizes vary from DN15 to DN2400.

The corrugated metal based gaskets are best to be used for:

Assembling of water-contact indicating gasket

Water-Contact Indicating Gaskets of Thermal-Expanded Graphite (PVTG)Specs 5728-007-12058737-2005

The water-contact indicating gaskets are intended to seal detachable joints of level indicators on boilers, containers, apparatuses and reservoirs for liquid media with nominal pressure of 2.5 MPa and t = 250 oC.

These gaskets are cut or punched from not reinforced or reinforced graphite sheets.

Advantages:

extension of thurnaround time due to that the service life of graphite gasket is 10 times longer than the service life of paronite gaskets;

decrease of chances of off-schedule shutdowns caused by seal failure, since the gasket material does not lose its sealing capacities in the course of time (does not age);

reducing expenses on expensive mica plates and other materials which become inoperative in case of leakage.

Braided Gland Packings Specs 2573-002-93978201-2008

The packings are intended for sealing of gland units of pumps, valves, mixers and other movable joints in such media as superheated steam, oil, heavy and light oil prod-ucts, gas and liquid hydrocarbons, acids, alkalies, melted or dissolved salts, organic substances, liquid and gas oxygen, etc.

The packings are made of yarns of various materials: reinforced thermal-expand-ed graphite tape, carbon fibers, expanded polytetrafluorethylene tape, aramid fibers, etc.

Advantages of TEG packings NG-100, NG-200 and NG-300:Use in a wide temperature range

They do not almost lose volume and weight, especially in a closed volume of the gland chamber, and therefore the gland is not needed to be tightened up regularly.

High heat conductionIt provides an efficient heat removal from the fraction area and allows to operate pumps without overheating even with no leakage required for cooling when asbestos or polytet-rafluorethylene packings are used.

High reliability and sealing capacity at high pressureThermal-expanded graphite is practically impenetrable to liquids and gases. Its excellent pressing ability enables to ensure sealability of the unit and to decrease the amount of us-able packing in half in comparison to asbestos packing.Reinforcement with heat-resistant wire (NG-200 packing) provides for high resistance to extrusion and wash-out at extremely high pressure and temperature, as well as resistance to vibratory loads that permits to use this packing for sealing of especially important valves.

Advantages of carbon packing NU-100 and NU-200High strengthAbrasion resistanceChemical resistance, except for strong oxidants

It is proposed as end and abrasion resistant ring together with TEG packing.

Advantages of polytetra� uorethylene packings NF-100 and NG-200High chemical resistance

They are intended for long-term operation in the most corrosive media at a tem-perature up to +260oC.

PurityIt doesn’t contain greases and other matters which can get into pumping medium

that, along with inertia and non-toxity, justifies its application in food, cosmetic and pharmaceutical industries.

Advantages of aramid packing NA-100High strength

It rules out the possibility that the packing damage under extremely high tighten-ing force, vibratory loads and sizable clearance gaps.

Exclusive abrasion resistanceIt is used for sealing in the most contaminated media where other seals are inef-

fective.To seal gland units, sets of different packings can be used.Combination of different packings in the same gland unit allows to solve more dif-

ficult problems which cannot be solved by use of separate packing, namely:- hermetic sealing in conditions of temperature cycling;- hermetic sealing in abrasive crystallizing media;- hermetic sealing in start-and-stop conditions;

Rule “Etalon”

Packing tools for packing extraction

Packing tools are designed to extract the used gland seal from valve cham-bers and pumps. The use of packing tools will help to avoid a damage of a chamber and a rod, as well as to avoid complete disassembly of a valve or a pump in case of the emergency replacement of the seal.

The packing tool is a flexible shaft made of steel rope (1) with metal T-shape handle (2), on the one side, and a special tip (3), on the other side. The tip looks like a corkscrew or self-tapping screw, a tip is made of high-quality steel hardened in accordance with special configuration which allow the tip to be screwed into various packings easily and properly.

Rule “Etalon” to Cut Packing

The rule “Etalon” is intended to cut workpiece of braided packing when manufacturing soft gland seals. Its design allows to cut the packing of the re-quired length without preliminary computations and gives the ordered angle of the end cut.

The rule can be of two types which differ in geometrical dimensions and sections of packing being worked.

Technical data

Principle of Operation:combine points on the rule corresponding to the rod diameter to agree with

the points of the spot plate corresponding to the packing section;fix the stop plate with the stop screw by turning it 90o�;cut the packing end at 45� with a knife using a slot at the end of rule as a

guide;move the packing along the frame until it contacts the end of the stop plate;cut the packing with the knife through the guiding slot.

Advantages:high accuracyminimal weight and size;ease of handling.

Modi� ed Sealing Materials of Thermal-Expanded Graphite

Modified sealing materials (foil, gasket material, rings, gaskets, pack-ings) are produced by injecting additives by various means and at various stages of process or by applying coatings or greases.

Modi� cation of sealing materials is made:

to reduce corrosion of surfaces to be sealed (it’s essential only for steels containing less than 17% of chromium);

to prolong the service life in the air at 500oC and to increase the upper limit of operating temperatures;

to improve mechanical properties;

to improve anti-friction properties;

to impart anti-adhesive properties.

Corrosion inhibitors, added into TEG sealing materials, enhance their pro-tection to 90-95%. Inhibitors are use to protect the sealing materials against at-mosphere corrosion, corrosion caused by sea-water, steam, salt solutions and other working media. More than 15 corrosion inhibiting additives developed by the Company have found application in different operating conditions. Inhibitor content can vary within 0.5 : 8.5% of the graphite component weight value. The corrosion inhibitors are not toxic, don’t impair mechanical properties and don’t decrease resistance of materials to oxidation.

Oxidation inhibitors, added, into TEG sealing materials, allow to increase operating temperature in the air to 600oC, and in some cases – to 700oC and higher. The Company has developed 5 oxidation inhibiting additives to suit vari-ous operating conditions. Inhibitor content varies 1.0 : 10.0% of the graphite component weight value. The oxidation inhibitors don’t affect mechanical prop-erties, and are not toxic. They are corrosive inert or have some corrosion inhibit-ing effect.’

In addition to oxidation inhibitors, in order to increase the upper limit of operating temperature coatings and thermal insulation inserts can be used.

Antifriction coatings and additives are used to modify TEG gland seals, carbon and armid yarns with the aim:

to step down the starting point of the equipment;

to decrease and/or stabilize friction coefficient in the course of operation process, particularly at a temperature over 450oC.

Anti-adhesive coatings of metal foils, natural oxide and other materials, as well as anti-adhesive additives developed by the Company permit to rule out or substantially reduce adhesion of TEG gaskets to flanges, especially when the flange surfaces are damaged.

We recommend to consult with the producer to choose modifying component of TEG seals and other asbestos-free materials to suit the specific operating conditions.
