Introduction to Precision Seamless Pipe
Precision seamless pipes are usually heat-shrinkable cold-rolled pipes. Cold-drawn precision steel pipes are a high-precision steel pipe material that has been cold-drawn or hot-rolled. Due to the advantages of precision steel pipes having no oxide layer on the inner and outer walls, withstanding high pressure without leakage, high precision, high smoothness, no deformation in cold bending, no cracks in flaring and flattening, etc. Its chemical components are carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, and Cr.
Precision Seamless Pipe Testing
In order to ensure the quality of pipelines, seamless precision steel pipe will be tested before leaving the factory, including mechanical performance testing, process performance testing, eddy current testing, ultrasonic testing, hydraulic testing, metallographic testing, etc.
Four Major Characteristics of Precision Seamless Pipe Processing
1.High precision
Precision seamless pipe processing is characterized by high precision and can meet the dimensional accuracy requirements of various industrial fields. Through advanced process technology and precision equipment, precise control of diameter, wall thickness, inner and outer diameters, etc. can be achieved to ensure the dimensional stability and consistency of the product.
2.High surface quality
During the processing of precision seamless tube, advanced polishing and brightening processing technologies are used to effectively reduce surface roughness and improve the smoothness and brightness of the steel pipes. At the same time, by optimizing material selection and processing technology, defects and residual stress on the internal and external surfaces can be reduced, the surface quality of the steel pipe can be improved, and the application fields with high requirements can be met.
3. High strength
Precision seamless pipe processing uses high-quality raw materials(stainless steel, duplex steel and nickel alloy material) and undergoes fine heat treatment and cold working processes to make the steel pipe have high strength and hardness. After processing, the seamless precision tube has a uniform and dense internal structure, good toughness and tensile properties, and can withstand work under extreme conditions such as high pressure and high temperature.
4. High corrosion resistance
stainless steel, duplex steel and nickel alloy material itself is corrosion resistant. And the special anti-corrosion treatment method used in the processing of Precision seamless pipes, the steel pipes have good corrosion resistance.
Precision Seamless Pipe Application
Seamless precision steel tubes are used in hydraulic system piping, automobile manufacturing piping, military industry, engineering machinery, Railway locomotives, aerospace, ships, injection molding machines, die-casting machines, machine tools, diesel engines, petrochemicals, power stations, boiler equipment and other industries.
