Flanges, gaskets and stud bolts used for flanged connections in piping systems (types of flanges/gaskets, specifications, dimensions and materials per ASME)

Flanges for Pipes and Piping Systems

In piping applications, a flange is used to join a pipe with other equipment (another pipe, a valve or a pump). Pipe flanges may be classified by shape (weld neck, blind, socket weld, threaded, etc), by facing type (RF, FF, RTJ), by material grade (cast and forged), and by specification (the ANSI/ASME B16.5 and B16.47 specifications… read more »

Y-Strainer and Basket Strainer for Pipes

Strainers are mechanical devices to retain (and remove) foreign particles from flowing liquids and protect equipment such as pumps and compressors. There are several types of strainers, including the Y, basket and duplex types. A critical element is the strainer’s screen, specifically its mesh size (perforation density).  PIPE STRAINERS TYPES There are two basic designs… read more »

Line Pipe API 5L Gr. B to X80 (PSL1/2)

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 »

Spectacle Blind, Flange Spade, Ring Spacer (ASME B16.48)

Spectacle blind, flange spade, and ring spacer are forged products used to blind pipelines (temporarily or permanently). These devices are cost-effective alternatives to isolation valves. A spectacle blind combines, in one single product, a flange spade and a ring spacer. Flange spades and ring spacers, as separate products, are used when the rotation of a spectacle… read more »

3LPE Coated, Lined and Clad Pipes (CRA)

What is the difference between external pipe coating and internal pipe-lining and cladding? External pipe coatings are used to protect the metal from corrosive environments (3LPE coated pipes are the most common choice). Internal lining (example PTFE) protects the pipe from corrosive fluids. Clad pipes (CRA) have the inner surface covered by higher grade materials to… read more »
