Steel pipes for process piping and pipelines

Different Types of Oil & Gas Pipes: Seamless, ERW, LSAW

Learn about the 3 types of steel pipes used in the petrochemical industry: seamless, ERW (electric resistance welding) and LSAW (longitudinal submerged arc welding). A seamless pipe is manufactured by drawing a solid steel billet through a piercing rod. Welded pipes are produced by cutting, bending, welding coils (ERW) or steel plates (LSAW). SEAMLESS PIPE Seamless pipes are produced starting from steel billets, that are… read more »

Carbon Steel Pipe A53/A106 Gr. B, A333 Gr. 6

Learn about the 3 most common specifications for carbon pipes: ASTM A53 (black and galvanized steel pipes, seamless and welded), ASTM A106 (seamless CS tubular for high pressure and high-temperature applications up to 750 degrees F), and ASTM A333 (low-temperature service). The article gives you an overview of these three specifications in terms of typical uses,… read more »

With this article, you learn about API 5L pipes. The API 5L specification covers seamless and welded pipes to convey oil, gas, water in the natural oil & gas and petrochemical industries. API 5L line pipes are available in multiple carbon steel grades, designated as Grade B, X42, X46, X52, X56, X60, X70, X80 and in PSL1 or PSL2… read more »

Pipe Color by Fluid Type

Color codes are, in some cases, applied on pipes and other piping materials (such as pipe fittings, flanges, and valves) to facilitate the identification, in the storage warehouse or on the field during project execution, of components manufactured in different materials. PFI ES-22 SPECIFICATION FOR PIPE COLOR CODING The table shows the pipe color coding… read more »
