Alloy pipe is a kind of seamless steel pipe with high performance, and its performance is better than the general seamless steel pipe. The high temperature resistance, low temperature resistance and corrosion resistance of this steel pipe are unmatched by ordinary seamless steel pipes, which is mainly due to its high chromium content. Alloy tubes are widely used in petroleum, aerospace, chemical, electric power, boiler, military and other industries.

The production process of alloy tube is mainly divided into raw material preparation, heat treatment, extrusion, cold drawing, annealing and inspection, etc. The manufacture of alloy tube usually uses stainless steel, nickel alloy, titanium alloy and other high-strength materials. Heat treatment refers to heating the raw material to a certain temperature, and then controlling the cooling rate to achieve the desired organization and properties. Extrusion is the core technology in the production of high pressure alloy tubes. Extrusion means that the raw material after heat treatment is placed in the extrusion press and the raw material is extruded into a tube shape by the pressure of the top outlet die. Cold drawing means that the extruded tube blank is placed on the cold drawing machine, and it is pulled into the required specification and size by cold pulling force. Annealing is to eliminate the stress generated during the cold drawing process and improve the mechanical properties of alloy tubes. The quality inspection of alloy pipe is an important link to ensure that the product meets the standard requirements.

In order to ensure product quality, we will arrange professional personnel to check product quality, packaging, weight, hardness, etc., according to customer requirements of product specifications, looking for high-quality and cheap cooperative factories in China, to provide customers with one-stop procurement services and quality assurance.

Excellent packaging: waterproof paper and plastic film + iron cover + at least three strapping straps + strapping straps fixed on iron or wood pallets can effectively protect products from corrosion and various climate changes during transportation.  Generally speaking, we ship from Shanghai, Tianjin, Qingdao and Ningbo ports.  We have worked with many experienced shipping companies for a long time to find the most suitable mode of transportation for you.
