Hot push forming process for stainless steel elbow

What is the hot push forming process for stainless steel elbow? The stainless steel elbow hot push forming process uses a special elbow pushing machine, a core mold and a heating device, so that the blank placed on the mold moves forward under the push of the pusher, is heated, expanded, and bent during the movement. The process of forming. The deformation characteristic of the hot thrust of stainless steel elbow is to determine the diameter of the blank according to the law of the volume change before and after plastic deformation of the metal material. The diameter of the […]

Types of flanges and flange connection

What are flanges? Flanges, also translated as rims, meaning symmetrical disc-like structures used to connect pipes, containers or fixed-shaft mechanical parts, usually with bolts and threaded structures for fixing . Flanges are disc-shaped parts that are most common in plumbing and flanges are used in pairs. In plumbing, flanges are primarily used for pipe connections. In the pipelines that need to be connected, a variety of flanges are installed, and the low-pressure pipelines can use wire-bonded flanges, and the welding flanges are used at pressures above 4 kg. A sealing point is added between the two flanges and then fastened […]

What is a welded pipe?

What is a welded pipe? Welded pipe is also called welded steel pipe. It is a steel pipe made by welding and forming a steel plate or strip steel. It is usually 6 meters long. The welded steel pipe has simple production process, high production efficiency, many varieties and specifications, and low equipment investment, but the general strength is lower than that of seamless steel pipe. Since the 1930s, with the rapid development of high-quality strip continuous rolling production and the advancement of welding and inspection technology, the quality of welded joints has been continuously improved, the variety specifications of […]

What is a pipe cross?

What is a pipe cross? Stainless steel cross, referring to a water pipe joint made of stainless steel, is a type of pipe used for branching of pipes. It is used where the four pipes meet. The pipe cross can have one inlet and three outlets, or an inlet and an outlet. The diameter of the outlet and the inlet may be the same or different. That is to say, straight line crossing and reduced crossover are available. The stainless steel cross has the equal diameter and the different diameter. The connecting ends of the equal-diameter cross are all the […]
