  The Main Application of Alloy Pipes Alloy pipes are mainly used to transport water, gas, natural gas, petroleum, and certain solid materials etc. Because the alloy pipe has a hollow section, it is widely used as a pipeline for conveying fluids and manufacture structural parts and mechanical parts, such as oil drill pipes, boiler pipes, automobile transmission shafts, bicycle frames, and steel scaffolding used in construction. The alloy steel pipes can be used to manufacture ring-shaped parts and increase the utilization rate of materials, simplify the manufacturing process, save materials and reduce processing time, such as rolling bearing rings, jack sleeves, etc. Compared with solid steel such as round steel, the weight of alloy steel pipe is lighter when the bending and torsion strength is the same, so alloy steel pipe is a kind of economical cross-section steel. Shanghai ShengQiu can supply alloy pipes which are used for boiler and heat exchanger. Standard and Grade:  #E...

 High Pressure Boiler Pipe   OD: 6MM-1100MM WT: 1MM-100MM   Application : Used for the manufacture of high temperature and high pressure steam boilers, seamless steel pipes for pipelines, furnace tubes for petrochemical industry, seamless steel tubes for heat exchanger and pressure pipelines, seamless steel tubes for high pressure fertilizer equipment and pipelines, and seamless steel pipes for other chemical equipment.   Alloy pipe is a kind of seamless steel pipe. it is divided into structure alloy seamless pipes and high pressure heat-resistant alloy pipes. The main difference is the production standard and the industry's annealing and tempering to change its mechanical properties for achieving the required processing conditions. Its performance is higher than ordinary seamless steel pipes. The chemical composition of alloy pipes contains more Cr. It is resistant to high temperature, low temperature and corrosion. Ordinary carbon seamless pipes do no...

  Thick Wall Steel Pipe And Its Application   The steel pipe with outer diameter to wall thickness ratio is less than 20 is called thick-walled steel pipe. Mainly used as petroleum geological drilling pipes, cracking pipes for petrochemical industry, boiler pipes, bearing pipes and high-precision structural pipes for automobiles, tractors, and aviation.   The biggest difference between thick wall steel pipe and thin wall steel pipe is the wall thickness. Generally speaking, thin wall steel pipes are cold drawn/rolled and thick-walled steel pipes are hot-rolled. If it is distinguished by measurement units, it is generally believed that thickness/ diameter equal to 0.02 is the demarcation point between thick wall steel pipes and thin wall steel pipes, thin wall steel pipes are less than 0.02 and thick wall steel pipes are more than 0.02. In terms of usage, thin-walled steel pipes are mostly used for pipelines and thick wall steel pipes are mostly used in blanks of h...
