Introduction
Stainless steel national standard reducing pipe is also called small head, used to connect different sizes of pipe; Generally, it is divided into two kinds of concentric reducing tube and eccentric reducing tube. When the projection of the two ports of the reducing tube is concentric circles, the stainless steel national standard reducing tube is called concentric reducing tube, and the projection of the eccentric reducing tube is a small circle cut to the outer circle.
Stainless steel GB reducing pipe also called GB eccentric size head, GB concentric size head. Different sizes of connected pipes are suitable for different industries. In the electric power, mining, metallurgy and other industries, material transportation, output, are using close distance, high pressure transportation, pipeline under considerable pressure, and withstand very serious wear, a single material of the pipeline is difficult to meet the requirements of this condition, especially elbow, concentric reducer, stamping elbow and other pipe fittings, because taking into account its safety, and service life, To improve the toughness, impact resistance and wear resistance of pipeline lining. The overall strength of pipe and elbow should also be considered.
Stainless steel national standard reducing pipe or expanding deformation pressing process, according to the pipe fittings of different materials and reducing conditions, determine the use of cold pressing or hot pressing. Under normal circumstances, cold pressing is used as far as possible, but hot pressing is appropriate for the case of serious work hardening caused by multiple diameter reduction, the case of thicker wall or alloy steel materials. Expanding forming is to use the tube blank less than the big end diameter of the reducing tube, using an internal die along the tube blank inner diameter expanding forming. The expanding process mainly solves the problem that the reducing tube with larger diameter is not easy to be formed by reducing diameter. Sometimes, according to the forming needs of materials and products, the method of expanding and reducing diameter is combined.
Stainless steel national standard reducing pipe pipe safety and reliability, health and environmental protection, economic application, thin wall of the pipeline and the development of new reliable, simple and convenient connection method, so that it has more advantages that other pipes can not be replaced, the application of the project will be more and more, the use of more and more popular, promising prospects.
Stainless steel reducing pipe connection modes are various, the common types of pipe fittings are compression type, compression type, loose type, push type, push thread type, socket welding type, loose type flange connection, welding type and welding and traditional connection combination of derived series connection. These connection modes, according to their different principles, its scope of application is also different, but most of them are convenient to install, firm and reliable. The sealing ring or gasket material used for connection is mostly made of silicone rubber, nitrile rubber and EPThree rubber in line with the requirements of the *** standard, so as to avoid the user’s worries.
