WAX PLANT PROJECT
1. SCOPE 1.1 This specification covers general requirements related to the identification of piping materials by means of color coding and marking done by stamping, stenciling, pressing and cast molding for the SMDS WAX PLANT Project in Bintulu Sarawak, Malaysia. 1.2 Identification requirements for GRE pipes and piping components shall be specified in the separate technical specifications. 1.3 This specification applies to the following types of piping materials: (1) (2) (3) (4) (5) (6) (7)
1.4 Color coding for identification of material and marking as required shall be carried out in the manufacturers shop. 2. GENERAL
2.1 Stencil marking shall be utilized a water – insoluble ink that does not contain substance which could harmfully affect the material such as metallic pigments, sulphur, zinc, sulphides and chlorides. 2.2 Marking by stamp shall be applied by low-stress hard-die stamping on painted background. Low-stress stamps shall be round nosed with a radius of 0.25mm minimum. 2.3 Marking shall be clearly indicated and shall not be easily erasable. 2.4 Color coding shall be done at locations that the painting does not cover the other markings and welding bevels. 2.5 Painting and stenciling shall be absolutely not be applied to:(1) (2) (3) (4) (5)
Inside the pipe, flanges or fittings or any item Threads Weld seam and bevels Symbols or markings would obliterate identification Gasket contact surfaces.
2.6 Casting shall have the charge or heat number cast in the material. The other required markings also to be cast-in in order of preference. 2.7 In case it is physically impossible to apply the required marking (e.g small size) it would be acceptable to apply the marking on a durable, securely affixed metal tag or to codify the marking.
