B366 WPN 45 Degree 80 Inch Stainless Steel Weld Elbows

B366 WPN 45 Elbow Pipe Fittings High Temperature Alloy Corrosion Resistant

A commonly used connection pipe fitting in pipeline installation, connecting two pipes with the same or different nominal diameters, so that the pipeline can be turned at a certain angle.

advantage
⑴ The production efficiency of stamping processing is high, and the operation is convenient, and it is easy to realize mechanization and automation. This is because stamping relies on punching dies and stamping equipment to complete processing. The stroke number of ordinary presses can reach dozens of times per minute, and high-speed pressure requires It can reach hundreds or even thousands of times per minute, and it is possible to get a stamped part per stamping stroke.
⑵ Stamping generally does not generate chips and scraps, consumes less materials, and does not require other heating equipment, so it is a material-saving and energy-saving processing method, and the cost of stamping parts is lower.
⑶ Stamping can process parts with a large size range and more complex shapes, such as stopwatches as small as clocks, as large as automobile longitudinal beams, covering parts, etc., plus the cold deformation and hardening effect of the material during stamping, and the strength and stiffness of the stamping are both Higher.
⑷ During stamping, since the mold guarantees the size and shape accuracy of the stamping parts, and generally does not damage the surface quality of the stamping parts, and the life of the mold is generally longer, the stamping quality is stable, the interchangeability is good, and it has the characteristics of "identical" .

The forming process of stamping elbows is complicated and needs to be welded according to different materials and uses, and gradually formed under a certain pressure. The forming of the stamping elbow needs to be carried out in accordance with certain procedures and strictly abide by the corresponding process, otherwise the produced stamping elbow will have quality problems. According to needs, a circular ring shell can be cut into 4 90 ° elbows or 6 60 ° elbows or other specifications of elbows. This process is suitable for
It is an ideal method to manufacture large push elbows of any size with a ratio of elbow pitch diameter to elbow inner diameter greater than 1.5D.
This process forming method is used in the production of different elbows, and shows good use value in different fields, so that the process has a good value in the production of different elbows.

The advantages of the forming process of large stamping elbows are mainly manifested in the following aspects:

⑴ No tube blank is required as raw material, which can save the cost of tube making equipment and molds, and can obtain any large diameter and relatively thin wall thickness push elbow. The raw material of this kind of stamping elbow is special, no need to add raw material of tube blank, and it is easy to control during processing.
⑵ The blank for processing the stamping elbow is a flat plate or a developable surface, so the blanking is simple, the accuracy is easy to ensure, the assembly and welding are convenient, the raw materials are easy to control during processing, the operation is relatively simple, there are no complicated procedures, and the welding and assembly are relatively convenient.
⑶ Due to the above two reasons, the manufacturing cycle can be shortened and the production cost is greatly reduced. Because it does not require any special equipment, it is especially suitable for processing large stamping elbows on site.
material

The material of stamping elbow includes carbon steel, stainless steel, alloy steel and other materials. Carbon steel stamping elbows are cheap and use large quantities. The alloy steel elbow is used in a special position.
stainless steel
The main difference between stainless steel stamping elbows and carbon steel elbows is the difference in material. The chemical composition contained in the elbow will keep the surface of the elbow from rust for a long time and is not easy to be corroded.
Stainless steel is a steel with stainless steel and corrosion resistance as its main characteristics, with a chromium content of at least 10.5% and a maximum of 1.2% carbon content.
The austenitic stainless steel matrix is ​​mainly austenitic structure (γ phase) with a face-centered cube structure, which is non-magnetic and is mainly strengthened by cold working (and may lead to certain magnetic properties).

Austenitic-ferritic (duplex) stainless steel

The matrix has a two-phase structure of austenite and ferrite (the content of the lesser phase is generally greater than 15%), a stainless steel that is magnetic and can be strengthened by cold working.
The ferritic stainless steel matrix is ​​mainly composed of a ferrite structure (α phase) with a body-centered cubic crystal structure, which is magnetic and generally cannot be hardened by heat treatment, but cold working can make it slightly strengthened.
