Whether in the field of production or in the manufacturing process of some large-scale equipment, we will find that more or less used in some of the pipe products, especially in the harsh requirements of the surrounding environment, the quality of the pipe selection is to a certain extent determines the effect of the use of the late and the advantages of the experience, so today for you to give an example of the relatively good performance of precision seamless tubes, their biggest advantage is that they are designed in a seamless way to avoid the trouble caused by leakage, then it may be worthwhile to learn more about the implementation of standards of precision seamless tubes. Seamless tube, their biggest advantage is that the design process in the early seamless connection, so as to avoid the trouble caused by leakage, the next may wish to come together to understand the implementation of product standards or classification of detailed examples of text it.
One of the executive standards for precision seamless tubes
1 structural seamless tubes (GB/T8162-2008) are seamless steel tubes used for general and mechanical structures.
2Seamless Steel Pipe for Fluid Transportation (GB/T8163-2008) is a general seamless steel pipe used for the transportation of water, oil, gas and other fluids.
3Low and medium pressure boiler seamless steel pipe (GB3087-2008) is used to manufacture a variety of structural low and medium pressure boiler superheated steam pipe, boiling water pipe and locomotive boiler superheated steam pipe and arch brick pipe with high quality carbon structural steel hot-rolled and cold-drawn (rolled) seamless steel pipe.
4 high pressure boiler seamless steel pipe (GB5310-2008) is used to manufacture high quality carbon steel, alloy steel and stainless heat-resistant steel seamless steel pipe for high pressure and above pressure water pipe boiler heating surface.
5 High-pressure seamless steel pipe for chemical fertilizer equipment (GB6479-2000) is a high-quality carbon structural steel and alloy steel seamless steel pipe for chemical equipment and pipelines with working temperature of -40~400℃ and working pressure of 10~30Ma.
6Seamless Steel Pipe for Petroleum Cracking (GB9948-2006) is a seamless steel pipe for furnace pipes, heat exchangers and pipelines applicable to petroleum refineries.
7Steel Pipe for Geological Drilling (YB235-70) is a steel pipe used for core drilling by geological department, which can be divided into drill pipe, drill collar, core pipe, casing and precipitation pipe according to the usage.
8Diamond core drilling seamless steel pipe (GB3423-82) is a seamless steel pipe for diamond core drilling drill pipe, core pipe and casing.
9 oil drilling pipe (YB528-65) is a seamless steel pipe used for oil drilling with inner or outer thickening at both ends. Steel pipe is divided into two kinds of car silk and not car silk, car silk pipe with joints coupling, not car silk pipe with butt welding method and tool joints coupling.
10 ships with carbon steel seamless steel pipe (GB5213-85) is the manufacture of ships class I pressure-resistant pipe system, class II pressure-resistant pipe system, boilers and superheaters with carbon steel seamless steel pipe. Carbon steel seamless steel pipe wall operating temperature does not exceed 450 ℃, alloy steel seamless steel pipe wall operating temperature exceeds 450 ℃.
11 automobile half-axle casing seamless steel pipe (GB3088-82) is the manufacture of automobile half-axle casing and drive axle casing axle tube with high-quality carbon structural steel and alloy structural steel hot-rolled seamless steel pipe.
12 High-pressure oil pipe for diesel engine (GB3093-2002) is a cold-drawn seamless steel pipe for manufacturing high-pressure pipe for diesel engine injection system.
13 Hydraulic and pneumatic cylinder barrel with precision internal diameter seamless steel tube (GB8713-88) is the manufacture of hydraulic and pneumatic cylinder barrel with precision internal diameter size of cold-drawn or cold-rolled precision seamless steel tube.
14 Cold-drawn or cold-rolled precision seamless steel tubes (GB3639-2000) are cold-drawn or cold-rolled precision seamless steel tubes with high dimensional accuracy and good surface finish for mechanical structures and hydraulic equipment. Selection of precision seamless steel pipe manufacturing mechanical structure or hydraulic equipment, etc., can greatly save machining man-hours, improve the material utilization rate, at the same time conducive to improving product quality.
15 Structural stainless steel seamless steel pipe (GB/T14975-2002) is widely used in the chemical, petroleum, textile, medical, food, machinery and other industries, corrosion-resistant piping and structural components and parts of the stainless steel made of hot-rolled (extruded, expanded) and cold-drawn (rolled) seamless steel pipe.
16 Seamless Stainless Steel Pipes and Tubes for Fluid Transportation (GB/T14976-2002) are hot rolled (extruded, expanded) and cold drawn (rolled) seamless steel pipes and tubes made of stainless steel used for the transportation of fluids.
17 shaped seamless steel pipe is in addition to the round pipe other than the other cross-section shape of the seamless steel pipe general term. According to the different dimensions of the cross-sectional shape of the pipe can be divided into equal wall thickness profiled seamless steel pipe (code for D), unequal wall thickness profiled seamless steel pipe (code for BD), variable diameter profiled seamless steel pipe (code for BJ). Profiled seamless steel pipe is widely used in various structural components, tools and mechanical parts. Compared with round pipe, shaped pipe generally have larger moment of inertia and section modulus, have larger bending and torsion resistance, can greatly reduce the weight of the structure, saving steel.
18 low-temperature piping seamless steel pipe (GB/T18984-2003) for -45 ℃ ~ -195 ℃ level of low-temperature pressure vessel piping as well as low-temperature heat exchanger piping seamless steel pipe.
The above is an example of precision seamless tube information, including product implementation standards and classification of detailed and meticulous description, it can be learned that this type of seamless tube because of advanced technology in the production and processing process, so you can avoid the existence of some places because of the leakage of the gap caused by the problem, and also to a certain extent to help consumers to achieve a more satisfactory and reliable safety and quality assurance. The above is the basic knowledge of the relevant aspects, interested in understanding the friends may refer to this part of the content, combined with their own needs of the budget, harvest a suitable and reasonable precision seamless tube.
