ASTM A234 Standards And Specifications

The ASTM A234 is a standard specification for Pipe Fittings of Alloy Steel(AISI 4130) used in moderate and high temperature service.

ASTM A234 - Pipe Fittings

ASTM A234 Pipe Fitting

ASTM A234 pipe fitting are used in various pressure regulation process, chemical industry, etc. The pipe fitting forms like Tee is used to combine (or divide) fluid flow. A swage nipple is a short stub of pipe, usually male-threaded steel, which connects two other fittings.

Scope And Manufacturing

ASTM A234 specification covers pipe fittings for pressure piping applications. These pipe fittings are manufactured through seamless or fusion-welded products with filler metal added. The process is performed by hammering, pressing, piercing, extruding, upsetting, rolling, bending, fusion welding, machining, the metal. The forming procedure are well taken care, so that it will not produce injurious imperfections in the fittings. Fittings, after forming at an elevated temperature, shall be cooled to a temperature below the critical range under suitable conditions to prevent injurious defects caused by rapid cooling. The fittings shall be subjected to tension test, hardness test, and hydrostatic test.

Siddhagiri Metals and Tubes is a supplier and distributor of AISI 4130 Alloy Steel pipe fittings which can be easily machined using conventional methods. However, machining becomes difficult when the hardness of the steel is increased. We are the worldwide supplier of pipe fittings for more than 30 years. We manufacture every product as per customers demand and is delivered on time with excellent packaging. We provide excellent service and product.
