90° Elbow Long Radius, Diam:4" ,Sch: S-XS ,ASME B16.9 ,Ends: BW ,ASTM A234-SMLS Gr. WPB.

In the pipeline system, elbow is a pipe fitting that changes the direction of the pipeline. According to the angle, there are three most commonly used elbows: 45 ° and 90 ° 180 °, and other abnormal angle elbows such as 60 ° are also included according to the needs of the project. Elbow materials include cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals and plastics.

The connection methods with pipes include: direct welding (the most commonly used method) flange connection, hot-melt connection, electric fusion connection, threaded connection and socket connection. According to the production process, it can be divided into: welding elbow, stamping elbow, push elbow, casting elbow, butt welding elbow, etc. Other names: 90 degree elbow, right angle bend, etc.

Carbon steel is an iron carbon alloy with carbon content of 0.0218% ~ 2.11%. Also called carbon steel. Generally, it also contains a small amount of silicon, manganese, sulfur and phosphorus. Generally, the higher the carbon content in carbon steel, the greater the hardness and strength, but the lower the plasticity.

Carbon steel products mainly include various bolts, studs, screws, nuts, washers, self tapping screws, assemblies, retaining rings, rivets, pins, flat keys, thread sheaths, etc. Standards include GB (national standard), DIN (German standard), ISO (International Standard), ANSI (American Standard), BS (British Standard), JIS (Japanese standard), etc. non standard products can also be processed according to drawings or samples.

Surface treatment mainly includes blackening, galvanizing, nickel plating, copper plating, Dacromet, carburizing, etc.

The products are widely used in all kinds of machinery, machine tools, automobiles, molds, hydraulics, petroleum, chemical industry, energy, pipelines, pumps and valves, ships, electronics, electricity, instruments, meters, environmental protection, water treatment, industrial control, food machinery, medical equipment, construction engineering, aerospace, furniture and product maintenance, and are deeply trusted and praised by our customers.
