The basic process of the big elbow is as follows

The basic process of the big elbow is as follows: firstly, a polygonal annular shell with a cross section or a polygonal fan-shaped shell closed at both ends is welded. After the internal pressure is filled with pressure medium, the internal pressure is applied. Under the action of internal pressure, the cross section gradually becomes a circle from the polygon and finally becomes a circular annular shell.According to the need, a circular annular shell can be cut into 4 90° elbows or 6 60° elbows or other specifications of the elbow, the process is suitable for making the middle diameter of the elbow and the inner diameter of the elbow ratio is more than 1.5 times of any specification of large elbow, is an ideal way to manufacture large carbon steel elbow.

Big elbow has a certain production cycle, because of the particularity of production and inventory, about the delivery time, please consult customer service before buying products.Large elbow is divided into seamless elbow and stamping elbow excellent products, the price is appropriate.It is a pipe fitting mainly used in pipe installation, and is used for connecting the bend of the pipe.Connect two pipes of the same nominal diameter to make a 90 degree turn.The following elbow factory introduces some characteristics of seamless stamping elbow in detail;Seamless elbow is divided into cold stamping and hot stamping, usually according to the material properties and equipment capacity to choose cold stamping or hot stamping.The forming process of cold extrusion elbow is to use the commonly used elbow forming machine to put the tube billet into the outer die. After the upper and lower die is closed, the tube billet moves along the reserved gap between the inner die and the outer die under the push rod to complete the forming process.The elbow made by the cold extrusion process of internal and external die has beautiful appearance, uniform wall thickness and small size deviation. Therefore, the stainless steel elbow, especially the thin-walled stainless steel elbow, is made by this process.The precision of the inner and outer die used in this process is high.The requirement of wall thickness deviation of tube billet is also strict.

Seamless elbow is widely used in petroleum, chemical, electric power, pharmaceutical, beverage water conservancy and other projects.Application of large elbow: connecting two pipes of the same nominal diameter, making the pipe turn 90 degrees.Divided by material carbon steel elbow, cast steel elbow, alloy steel elbow, stainless steel elbow, copper elbow, aluminum alloy elbow, etc.By making method, it can be divided into push elbow, stamping elbow, forging elbow, casting elbow, etc.According to the manufacturing standard, it can be divided into national standard, electric standard, water standard, American standard, German standard, Japanese standard, Russian standard, etc.
