brief introduction
 
Elbow is a commonly used connecting pipe fitting in plumbing installation. It is used for the connection at the bend of the pipeline and to change the direction of the pipeline.
Other names: 90 ° elbow, right angle bend, love bend, stamping elbow, pressing elbow, machine-made elbow, welding elbow, etc.
Purpose: connect two pipes with the same or different nominal diameter to make the pipeline turn 90 °, 45 °, 180 ° and various degrees.
Bending radius less than or equal to 1.5 times of pipe diameter belongs to elbow, and bending radius greater than 1.5 times of pipe diameter belongs to elbow
 
 
technical requirement
 
1. Since most of the pipe fittings are used for welding, in order to improve the welding quality, the ends are turned into grooves, with a certain angle and a certain edge. This requirement is also strict. There are regulations on the thickness of the edge, the angle and the deviation range. The surface quality and mechanical properties are basically the same as those of pipes. For the convenience of welding, the steel grade of pipe fittings and connected pipes is the same.
2. That is, all pipe fittings shall be subject to surface treatment, and the iron oxide scale on the internal and external surfaces shall be sprayed off by shot peening, and then coated with anti-corrosion paint. This is for export needs. Moreover, in China, it is also to facilitate transportation and prevent corrosion and oxidation.
3. That is, the requirements for packaging. For small pipe fittings, such as export, wooden boxes need to be made, about 1 cubic meter. It is stipulated that the number of elbows in such boxes can not exceed 1 ton. The standard allows suits, that is, large sets and small sets, but the total weight can not exceed 1 ton. For large pieces y, a single package is required. For 24 ", a single package is required. Another is the packaging mark, which indicates the size, steel number, batch number, manufacturer's trademark, 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.
