1. Longer life, ordinary steel pipes have a certain lifespan. When ordinary materials are treated with anticorrosion, their lifespan can be as long as 20-30 years or longer. It can be described as the "lifetime star" in the pipeline, and it can be saved in use. It saves replacement, maintenance and
The main purposeGalvanized pipes are usually used to loosen gas and heating. Galvanized pipes are also used as water pipes. However, after a few years of use, a large amount of rust will be generated. The yellow water that flows out will not only contaminate sanitary ware but also breed bacteria on
It is recommended to use polyethylene anti-corrosion adhesive tape with a special primer for external anti-corrosion of the pipeline. This anti-corrosion process does not require high requirements on the construction site and is pollution-free. It can be prefabricated for corrosion protection, and t
1. Manufacturing and processing methods of seamless steel pipes:(1) Hot rolling (extruded seamless steel tube): round tube billet→heating and piercing→three-roll cross-rolling, continuous rolling or extrusion and one-off tube→sizing (or reducing)→cooling→straightening→hydraulic pressure Test (or fla
The stainless steel flange is not completely rust-proof, but its oxidation resistance is stronger than that of ordinary steel, so it is called stainless steel.Stainless steel not only can resist atmospheric oxidation, but also can corrode in acid, alkali, and salt media. However, the size of its cor
API casing threads are not suitable for the development of high-pressure gas fields, so many manufacturers have developed special joints with their own characteristics. Among them, the gas-sealed special joint thread types suitable for the development of gas fields are:1. NS-CC thread (developed by
First, the procurement needs to understand the type of steel pipe.1. According to the type: straight seam steel pipe, seamless steel pipe , spiral steel pipe, etc.2. cross-sectional shape classification of straight seam steel pipe classification : square tube, rectangular tube, elliptical tube, fla
The stainless steel seamless pipe is a long strip of steel with a hollow section and no seams around it. Stainless steel seamless pipe features:First, the thicker the wall thickness of the product, the more economical and practical it is. The thinner the wall thickness, the
