Changsha Xiangjia Metal Materical Co., Ltd.

Hot-dip galvanized steel pipes   are widely used in construction, machinery, coal mines, chemicals, electric power, railway, automobile industry, highways, bridges, containers, sports facilities, agricultural machinery, petroleum machinery, prospecting machinery, greenhouse construction and other manufacturing industries. Galvanized steel pipe is hot-dip galvanized or electro-galvanized covered steel pipe. Galvanizing can increase the corrosion resistance of steel pipes and prolong the service life. It has a wide usage. It is been used as pipeline pipes for general low-pressure fluids such as water, gas, and oil, also used as oil well pipes, oil pipes in the petroleum industry, especially in offshore oil fields, oil heaters in chemical coking equipment, and trestle pipes. Changsha Xiangjia Metal Materical Co., Ltd.  is professional manufacture in SSAW steel pipe, galvanized steel pipe, seamless pipe etc. with various grades and sizes. Years of production experience and manufacturing fa

Polyurethane foam insulation steel pipe   used excellent special resin, adopts advanced equipment and production technology and added corona treatment technology in the production process to increase the surface performance of the product. After testing, the technical performance index of the product has reached the CJ/114-2000 standard. Features: Polyurethane foam insulation steel pipe has the characteristics of high strength, impact resistance, environmental stress crack resistance, corrosion resistance, low temperature resistance, easy welding, convenient construction, strict sealing and no leakage. Usage: The pipe material is: "two-step method" (ie, pipe-in-pipe) to produce "cyanopolymer" buried thermal insulation steel supporting products, which are widely used in foreign countries as the outer protective layer of thermal insulation pipes. 

ERW steel pipe   is straight seam electric resistance welded pipe, used to transport oil, natural gas and other vapor-liquid objects, and can meet various requirements of high and low pressure. The biggest difference between ERW steel pipe and seamless steel pipe is that ERW has a seam. With the development of production technology, ERW steel pipes have become seamless, which can be divided into geometric seamless and physical seamless. Geometric seamless is to remove internal and external burrs of ERW steel pipe. Due to the continuous improvement and perfection of the structure and tool of the internal burr removal system, the internal burr can be controlled at -0.2mm ~ O.5mm. Physical seamless means that there is a difference between the metallographic structure inside the weld and the base metal, which leads to the decline of the mechanical properties of the weld area, and should take measures to make it uniform and consistent.

Seamless steel pipe   is a kind of strip steel. The pipe has a hollow section. Can be used for fulid transferring. Such as pipes that transfers oil, natural gas, gas, water and some solid material. It dosen't rust. Which extends its life. Most importantly, it is extraordinary clean and no poisonous material contained. Compared to other seamless plastic pipes, it has much stronger mechanical resistance.  High temperature and high pressure environment is acceptable, the way to install is the same as other pipes. It is also able to replace other pipes to transfer water and other liquid. These are its characteristics: High precision, small batch production is available. Small diameter Weldability strong, high compression capability. Superior steel pipe performance, relatively dense metal. Complex steel cross area High precision cold drawn products, good surface quality. To find out more, please visit our official website  http://www.xiangjiasteel.com/
