Concentric Reducer Eccentric reducer
Description
Stainless steel concentric eccentric reducer
The size of the stainless steel reducer is also called the big head. One of the chemical pipe fitti•ngs, used for the connection of two different diam↔eters. It is divided into two kinds of concentric head and eccentric size. ✔Material includes stainless steel head, alloy steel, car™bon steel head, etc.
Small head (reducing pipe) is a type of pipe fitting used at the reducing point of ≠the pipe. Forming process is usually used for reducing size pressi✘ng, expanding size pressing or reducing size plus expanding size pressing, for s↔ome specifications of reducing diameter pipe can also be used stamping forming.
A. Reducing/expanding diameter forming
The reducing size of the head forming process is to put the tube billet with ∑the same diameter of the big end of the head into the forming die, through the pressing along th e axial direction of the tube billet, so that the metal movement along the die ca←vity and shrinkage forming. According to the size of reducing pipe, it can be dividΩed into one pressing forming or multiple pressing forming.
B. Stamping forming
There are various connecting ways of stainless steel head. The common pipe fitting types ±include compression type, compression type, live con÷nection type, push type, push thread type, socket welding type, live connection type flange conn™ection, welding type and derived series connecting wayγ combining welding and traditional connection. These connection mode, according to its pγrinciple is different, its applicable scope is also different, but most are easy to install, fi♦rm and reliable. Generally in construction machinery, large tee ha<s the characteristics of large diameter, thin wall, poor rigidity and smooth a↑ppearance. Buckling forming method: there are three commonly used meth≈ods, one is called extension method, the other is called stamping method, there are 3-4 rollers, two fixed rollers, a debugging roller, debugging fixed roller distance, th e finished pipe fittings are buckling. Other substances that can♣ cause transparency problems include semiconductor data silicon, gallium arse↑nide, certain coatings, optical data such as silver chloride, sapphire, quartz, sodium chlor ide, germanium, and many special crystal products. The sealing ring ∑or sealing gasket used for connection is made of silicone rubber, nσitrile rubber and EPDM rubber that meet the requirements of national standards, so as to avoid ∑the worries of users.
