Detailed introduction of ASME American Standard Tee butt welding pipe fittings

In the piping system, ASME American Standard Tee butt welding pipe fittings are pressure piping components used to change the direction or diameter of pipes, branch pipes and achieve special connections in production equipment such as petrochemical power. Fittings for pipe connections, especially for long pipelines and pipelines that do not require frequent disassembly. Due to the change of flow direction and flow area of the medium at its installation position, the internal and external stress conditions are more complicated, so the quality level of the pipe fittings directly affects the safe and stable operation of the entire pipeline system. They are available in a variety of product types such as 90° elbows, 45° elbows, tees, crosses, caps, concentric reducers, eccentric reducers, flanged nipples. The company's products in this category are in compliance with ASTM A403 and ASTM A234 standards. ASME American Standard Tee butt welding pipe fittings are mainly suitable for high-pressure pipelines requiring high pressure, precision-sized equipment and Various other high voltage fields.

The elbows of butt welding pipe fittings are divided into 45°, 90° and 180°. The 90-degree elbow and the 180-degree elbow can be divided into long radius and short radius according to the curvature. 45° only has a long radius and no short radius. The long radius elbow refers to its radius of curvature equal to 1.5 times the outer diameter of the pipe, that is, R=1.5D. A short radius elbow means that its radius of curvature is equal to the outer diameter of the pipe, ie R=1.0D. (D is the diameter of the elbow, and R is the radius of curvature. D can also be expressed in times.) The factory can also customize 60° or other abnormal angle elbows according to customer (engineering) needs. The main (most commonly used) connection methods with pipes are direct welding, flange connection, thread connection and socket connection.

According to the pressure level, there are about seventeen kinds, which are the same as the American pipe standards, including: Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS; Sch80, Sch100, Sch120, Sch140, Sch160, XXS, the most commonly used are STD and XS.

The production standard of ASME American Standard Tee butt welding pipe fittings is ASME B16.9. The standard outer diameter size is 1/2" to 80". Generally, seamless steel pipes are used as raw materials within 24", and 26"-80" Most of them are stamped with steel plates and then welded. The maximum wall thickness can reach 60mm, and the minimum can reach 1.24mm. The most commonly used steel types are carbon steel, alloy steel and stainless steel.
