GENERAL NOTES FOR PIPING MATERIAL SPECIFICATION

1.0 SCOPE

1.1 This specification (PMS) covers the various piping classes for Process and utility Piping.

2.2 Editions and addenda (if any) of referred Codes and Standards shall be as per the Job Engineering Design Basis (Piping).

2.3 For the sake of brevity, the initials of the society to which the codes are referred to may be omitted in the specification. For example; B 16.5 is a code referring to ASME; A106 is a standard referring to ASTM.

3.0 MATERIAL SPECIFICATIONS

3.1 Individual piping Class has been generally designed to cover a set of services operating within pressure-temp. combination as per ASME B 16.5 / B16.34 or part of it.

3.2 The PMS shall be strictly adhered to in the design, requisitioning, purchasing, fabrication and testing of the piping system. However, deviations of material may occur due to design conditions and/or availability. All substitutions must be duly approved.

3.3 Unless mentioned otherwise, pipe thicknesses in the specs are for above ground piping.

4.0 CLASS DESIGNATION CODE

The class designation shall consist of not more than three components made up of a letter, number & letter; e.g.B I A.

4.1 The first letter indicates pressure rating.

5.3 All pipe threads shall conform to ASME B1.20.1 except where otherwise noted.

5.4 Pipe thicknesses not covered in different classes of this specification shall be calculated to meet specific job requirement based on actual max. design condition to economize on thickness. However, in such cases the thickness shall be calculated at not less than 80% of class rating unless defined otherwise in the Job Engineering Design Basis (Piping).

9

5.5 Maximum of 10% of Corrosion Allowance may be adjusted to optimize on pipe schedule. However, if CA is suffixed by 'minimum', this downward adjustment shall not be used.
