The difference between the Pipeline, heat-resistant steel pipe, machinery and industrial pipe, oil casing pipe
 
· Pipeline -: general working pressure greater than 6 MPa, used as a warm steam, water, gas, natural gas and oil pipelines. No special requirements on such mechanical properties of the steel pipe, the surface quality and accuracy of the geometric dimensions, but it should be hydrostatically tested to determine its carrying capacity. Pipe should be subject to a pressure test, in order to ensure the quality of the weld. This type of pipe commonly used A steel or high-quality low-carbon structural steel.
 
Thermal equipment with steel pipe: manufacturing equipment working under high temperature and high pressure conditions, such as boiling water tube boiler, fire tube steam superheater tubes, the steam reheater tubes and steam pipeline thermal equipment, pipe. The working pressure in the high pressure boiler 10 ~ 14MPa, temperature at 450 ° C or about ships, some of the superheater and reheater tube wall temperatures up to 600 ° C to 620 ° C. Therefore, the kind of steel requires not only having a good room-temperature mechanical properties, and must also have good high temperature properties (including high temperature strength and ductility, resistance to oxidation, corrosion resistance and microstructure stability, etc.), bending and welding or the like process performance. Kind of steel pipe high quality carbon structural steel, low alloy steel and high alloy steel. Finished after heat treatment and hydrostatic test, we need to do the mechanical properties, macrostructure and microstructure of woven inspection, as well as flattening, flaring, curling and bending process performance test.
 
· Mechanical industrial pipe: machine parts used to manufacture hydraulic cylinders, cylinder, piston, pressure vessels, rolling bearings, coat, and a variety of ordnance. The characteristics of this type of steel pipe is required to have higher dimensional accuracy of the geometry of the trial, and good mechanical properties and surface quality, and some also required to have good abrasion resistance. This type of steel pipe and more generally to produce high-quality carbon structural steel, low alloy steel or special steel.
 
· Petroleum, geological drilling pipe: drill pipe used in the oil and geological drilling, the fixed borehole with casing, sampling the core pipe, oil tubing, and steel pipe manufacturing pipe joints extracted from the wells are considered this category. Such pipe subject to a great deal of work stress at work and subjected to groundwater and gas of high pressure and corrosive effect, it should have a high strength and corrosion resistance. This type of steel pipes are made of high-quality carbon steel and low alloy steel, finished in need of car rod working, in order to ensure the strength and tightness of the threaded portion, and some wire in the car before the first pipe end upsetting. Kind of steel pipe factory should be accompanied by a pipe connector box protective cover to prevent thread damage during transport.
