ASTM A105 threaded fittings are forged fittings made of carbon steel material, generally produced according to the American standard ASME B16.11 or the British standard BS3799 production standard. Carbon steel threaded fittings include various types such as threaded elbows, tees, cross, couplings, nipples, pipe plugs, bushings, caps, and unions etc. ASTM A105 carbon steel pipe fittings are widely used in various pipeline systems due to their superior performance and low cost.

Forged socket weld elbow is a common type of pipeline accessory in the forged series of pipe fittings. Its production process is made of round steel or steel ingots as raw materials, formed by die pressing forging blanks, and then processed by a lathe to form a high-pressure elbow pipeline connection accessory. According to different bending angles, it can be divided into two forms: 45degree and 90 degree socket weld elbow​.

Types Of Stainless Steel 304H Butt Welded Pipe Fittings Stainless steel 304H butt welded pipe fittings are a high carbon version of stainless steel 304 material fittings, and the common American standard material is ASTM A403 WP304H. ASTM A403 is a material standard developed by the American Society

ASME B16.5 is a standard developed by the American Society of Mechanical Engineers (ASME), which specifies in detail the dimensions, tolerances, markings, materials, and other related requirements for pipeline flanges and flange connections. Carbon steel flange refers to a flange forged from carbon steel material. ASME B16.5 carbon steel flanges typically refer to flanges that comply with ASME B16.5 standards and are manufactured using carbon steel materials. Carbon steel is a commonly used metal material with good strength, plasticity, and weld ability, therefore it has been widely used in industrial manufacturing. This type of flange can be used in various pipeline systems, especially in environments that require high pressure and temperature resistance.

ASTM A182 forged pipe fittings are mainly divided into two categories: socket welding pipe fittings and threaded pipe fittings.Socket welding fittings include: socket elbow, socket tee, socket cross, socket coupling, socket cap, socket boss, socket 45 degree tee, socket union,etc.Threaded pipe fittings include: threaded 45 degree elbow, threaded 90 degree elbow, threaded tee, threaded cross, male and female 90 degree elbow, threaded coupling, threaded boss, threaded cap, threaded plug, threaded bushing, threaded union, threaded swage nipple, hex nipple,etc.

ASME B16.5 Class 300 flanges have a variety of types and can be classified according to the connection method:welding neck flange,slip on flange，socket welding flange，threaded flange，lap joint flange，blind flange。According to material:carbon steel flange,alloy steel flange,stainless steel flange,duplex stainless steel flange etc.
