Steel butt welded fittings -90 degree elbows

The 90° elbow is the most commonly used elbow in pipeline installation,  it is a pipe fitting that changes the direction of the pipeline in the pipeline system. 90° elbow can be divided into long radius (LR) elbow  short radius (SR) elbow according to the bending radius. Other commonly used elbow in fluid pipeline construction are 45° elbow  180° elbow. Our company can also customize other non-standard elbow according to engineering needs.

The 90° elbow is the most commonly used elbow in pipe installation,  it is a pipe fitting that changes the direction of the pipe in the pipe system. Butt welding elbow is welded by two steel plates, the general large diameter elbow is butt welding process, so in the industrial use of the general diameter of more than 600 are basically butt welding elbow. Butt welding 90° elbow can be divided into long radius (LR) elbow  short radius (SR) elbow according to the bending radius. Other commonly used elbow in fluid pipeline construction are 45° elbow  180° elbow. Our company can also customize other non-standard elbow according to engineering needs.

The American standard ANSI/ASME B16.9 elbow is commonly referred to as the elbow produced in accordance with the American ANSI  ASME standards, ANSI is the American national standard, ASME is the American Society of Mechanical Engineers standard. ASME  ANSI standards cover the vast majority of industrial fields, including materials, processing, technology, testing  so on,  ASME references many ANSI standards.

ANSI/ASME B16.9 90° elbow production requirements

The connection method of the elbow parts is mostly completed by welding process, in order to ensure high quality, the end of the elbow is made into a groove, reserve a certain slope,  the elbow band edge, which need to be strictly controlled, the slope  edge size have a certain value area size, the elbow surface manufacturing,  the pipeline manufacturing is  much different.

The components contained in the elbow need to be treated again by the surface layer, the oxidized elbow inside  outside the layer, through the spray process, evenly apply the anti-rust paint, to facilitate the transportation of the product, easy to export to foreign markets, so that the elbow product to reduce wear, which is a very important process.

In the pipeline system, butt welded pipe fittings are used to change the direction  diameter of the pipeline, branch the pipeline  realize the special connection function of the pressure pipe components in the production equipment such as petrochemical power, it is a kind of pipe fittings connected with the pipe by welding method, especially suitable for long pipelines  pipelines that do  need to be disassembled frequently. Due to the change of the flow direction  flow area of the medium in its installation position, its internal  external stress is more complicated, so the quality grade of the pipe fittings directly affects the safe  stable operation of the entire pipeline system. They are available in a variety of product types, such as 90° elbow, 45° elbow, tee, tee, cap, concentric reducer, eccentric reducer, flanged nipple. The company's products comply with ASTM A403  ASTM A234 standards. Welding pipe fittings are mainly used in petrochemical industry, medicine  health, electric power, aerospace, military, fire protection, metallurgy, shipbuilding, gas, nuclear power,  environmental protection  other requirements of high pressure high-pressure pipeline, size requirements of precision equipment  other high-pressure fields.
