PTFE Lining Steel Reducing Cross, Reducing Cross.

Reducing pipe is a kind of pipe fitting used for pipeline caliber. The commonly used forming process is reduced-diameter pressing, expanded-diameter pressing or reduced-diameter plus expanded-diameter pressing, and certain specifications of different-diameter pipes can also be formed by stamping.
Reducing / expanding forming
The reducing and forming process of the large and small heads is to put the tube blank equal to the large end diameter of the small and large heads into the forming mold, and press the tube along the axial direction of the tube blank to move the metal along the mold cavity and shrink the mold. According to the size of the reducer, it can be divided into one press forming or multiple press forming.
Stamping
In addition to using steel pipes as raw materials to produce large and small heads, some sizes of large and small heads can also be produced by using a steel plate stamping process. The shape of the die used for stretching is designed with reference to the inner surface size of the large and small heads, and the steel plate after blanking is stamped and stretched with a die.
Specification:



 

Features:
High use temperature: under the condition of strong corrosive medium, it can meet the use temperature range of -60 ºC ~ 150 ºC, within this temperature range (except for molten alkali metal, elemental fluorine and aromatic hydrocarbons), it can meet all chemical media;
Vacuum resistance: In the range of -60 ºC ~ 150 ºC, it can be used under vacuum conditions. In chemical production, local vacuum conditions are often caused due to cooling, longitudinal discharge, and asynchronous operation of pump valves;
High pressure resistance: can withstand the use pressure of up to 3mpa in the temperature range;
Impermeability: Use high-quality resin, processed into a high-density, sufficient thickness ptfe lining layer through advanced lining technology, so that the product has superior impermeability;
The integral molding sintering process lining solves the problem of steel-fluorine cold and hot expansion and contraction and achieves synchronous expansion and contraction;
It adopts standardized size preparation, especially the pipes and pipe fittings used in chemical pipelines have strong interchangeability, which provides great convenience for installation and spare parts.
Carbon steel, stainless steel, and other materials can be customized according to customer needs.
