Carbon Steel Pipe, Plate, Fittings & Flanges — Complete Guide
Carbon steel is the backbone of process piping and pressure equipment. From carbon steel pipe in ASTM A106 Gr.B to carbon steel plate in SA 516 Gr.70, plus alloy plate, carbon steel fittings and carbon steel flanges — Creative Metal Industries supplies the complete carbon and alloy steel range with full documentation from its Vadodara stockyard.
Carbon Steel Pipe — ASTM A106 Gr.B & API 5L
Carbon steel pipe is specified by service. ASTM A106 Gr.B is the seamless carbon pipe for high-temperature service — steam lines, refinery process piping and boiler connections. ASTM A53 covers welded and seamless pipe for general and lower-temperature use, while API 5L Gr.B is the line-pipe grade for oil and gas transmission. Creative Metal Industries stocks carbon pipe from 6NB to 600NB, SCH 40 to XXS, with IBR Form III-C where the application demands it.
Carbon Steel Plate — SA 516 Gr.70, IS 2062 & A36
SA 516 Gr.70 is the pressure-vessel quality carbon plate for boilers, tanks, heat exchangers and pressure vessels — prized for its notch toughness at moderate and low temperatures. IS 2062 E250/E350 and ASTM A36 cover structural-grade carbon plate for general fabrication. NACE/HIC tested SA 516 Gr.70 is available for sour-service equipment. Plates run 5mm to 200mm thick and can be cut-to-size.
Alloy Steel Plate — ASTM A387
Alloy plate to ASTM A387 (Grades 5, 9, 11, 12, 22, 91) is used for high-temperature pressure-vessel service where plain carbon steel loses strength. Chromium-molybdenum alloy plates resist creep and hydrogen attack in refinery reactors, hydrocrackers and boiler drums. Supplied normalised and tempered, with IBR certification available.

Carbon Steel Fittings & Flanges
Carbon steel fittings — buttweld elbows, tees, reducers and caps to ASTM A234 WPB (ASME B16.9), plus forged socket-weld and threaded fittings to ASTM A105 (ASME B16.11). Carbon steel flanges in A105 (and A350 LF2 for low-temperature service) cover weld-neck, slip-on, blind, SORF and SWRF types to ASME B16.5 and B16.47. Matching alloy steel fittings (WP11/WP22/WP91) and flanges (F11/F22/F91) complete high-temperature piping systems. All carry MTC and IBR Form III-C where required.
