In many construction sites, we use this kind of welding for priming, which can effectively ensure its quality and has certain construction difficulties. Therefore, careful and skilled welders should be selected for this work.According to the purpose, it can be divided into oil well pipe (casing, pipeline pipe, boiler pipe, mechanical structure pipe, hydraulic prop pipe,Almere StadStainless steel chain plate mesh belt, gas cylinder pipe, geological pipe chemical pipe (high-pressure chemical fertilizer pipe, petroleum cracking pipe) and marine pipe.Almere Stad,Spcespce & mdash; & mdash; refers to cold-rolled carbon steel sheet and strip for deep drawing, equivalent to China Al () deep drawing steel. If it is necessary to ensure non aging property,Almere StadStainless steel square tube, add n at the end of the brand as spcen. Quenching and tempering code of cold-rolled carbon steel sheet and strip: annealing status is a, standard quenching and tempering is s, / hard is / , hard is / , hard is . Surface processing code: dull finish rolling is D, bright finish rolling is B. spcc-sd represents cold-rolled carbon sheet generally used for standard quenching and tempering and matt finish rolling. Another example is spcct-sb It refers to cold-rolled carbon sheet with standard quenching and tempering and bright processing and required to ensure mechanical properties.The corrosion resistance of stainless steel depends on chromium, but because chromium is an integral part of steel, the protection is different.Rongai,At low temperature, ferritic stainless steel pipe has low-temperature brittleness like carbon steel, but austenitic steel does not. Therefore, ferritic or martensitic stainless steel produces low-temperature brittleness, while austenitic stainless steel or nickel base alloy does not show low-temperature brittleness. Sus (Cr) and SUS (cr) of ferritic stainless steel pipe It shows that the impact value decreases sharply at low temperature. Therefore, the embrittlement temperature is in the range of - ℃ to - ℃Model & mdash; It has better temperature resistance.There are three main reasons for oxidation of stainless steel: production process high purification process can be considered. With the help of C and N level, which is one of the reasons for oxidation of steel products. In terms of production process and product characteristics, forming a thin oxide film on the product surface is the basic process to avoid oxidation, and it is also one of the main characteristics of steel products different from other steel products. It is specialized in products, renewable resources business and business package Including: stainless steel plate, stainless steel coil, stainless steel belt and stainless steel pipe. However, when the oxide film is incomplete and discontinuous due to insufficient or negligent production process, resulting in the appearance of oxidation of the product.

Stainless steel pipe packing bag is nothing more than the function of protecting the surface of stainless steel pipe, so most stainless steel pipe users do not have to question this point.The design shall be carried out according to the soil, water, grooved section, load conditions and other factors of the trench, which shall be firm and reliable to prevent collapse and support and shall not hinder the pipe laying and pipe stabilization.When using this method, it should be noted that the water-soluble paper should be double-layer and must be pasted well, resulting in cutting of the weld junction and re welding resulting in loss of argon protection of the inner weld and oxidation, which can not ensure the welding quality and seriously affect the construction period. Therefore, the water-soluble paper should be strictly checked and pasted before welding.Quality inspection report,Accounting for about % - % of the total steel, it is widely used in the national economy. Because the steel pipe has a hollow section, it is suitable for gas and solid transmission pipelines; at the same time, the steel pipe has large section coefficient and high flexural and torsional strength, so it has also become an important material in various machinery and building structures. Stainless steel is used Under the condition of equal weight, the structure and components formed by pipe have a larger section modulus than solid parts. Therefore, stainless steel pipe itself is an economic section steel that saves metal. It is an important part of steel, especially in oil drilling, production and metallurgyStandard classification - classification: national standard GB industry standard Yb local standard enterprise standard qcb- classification: product standard packaging standard basic standard - standard level (divided into three levels): y level: international advanced level I level: international general level H level: domestic advanced level - national standard: stainless steel bar (level I) gb- stainless welding disc Park (level H)The intergranular corrosion of austenitic stainless steel can be prevented by adding Ti, Nb and other elements that can form stable carbides (tic or NBC) and avoiding the precipitation of crc on the grain boundary.

Deformation strengthening of austenitic stainless steel stainless steel has good cold deformation performance. It can be cold drawn into very thin steel wire and cold rolled into very thin steel strip or steel pipe. After a large amount of deformation, the strength of the steel is greatly improved, especially when rolling in the subzero temperature zone. The tensile strength can reach more than MPa. This is because in addition to the cold hardening effect, there are also superimposed Deformation induced M transition.knowledge,Model & mdash; After that, the second widely used steel is mainly used in food industry and surgical equipment. Molybdenum is added to obtain a special corrosion-resistant structure. Because it has better chloride corrosion resistance than it, it is also made & ldquo; Marine Steel & rdquo; To use. SS is usually used in nuclear fuel recovery units. Grade stainless steel generally meets this application grade.In polluted air (such as atmosphere containing a large amount of sulfide, carbon oxide and nitrogen oxide), in case of condensed water, acetic acid liquid points will be formed, which will lead to chemical corrosion.When the stainless steel pipe with solid core welding wire is prefabricated, the welded junction can usually be rotated for welding, and the ventilation is very easy. At this time, the blocking plate is usually used to block both sides of the welded junction in the pipe, and the bottom welding is carried out for the protection of ventilation (see Table ), and the outside is blocked with adhesive cloth.Almere Stad,Stainless steel pipe, which was produced and used in China at the end of the s,Almere StadHigh temperature resistant stainless steel belt, is a new family emerging in the field of pipe materials. It has been widely used in building water supply and direct drinking water pipelines.Stainless steel grade group Series & mdash; Chromium nickel manganese austenitic stainless steel series & mdash; Chromium nickel austenitic stainless steel model & mdash; Good ductility, used for molding products. It can also be machined to harden rapidly. Good weldability. The wear resistance and fatigue strength are better than those of stainless steel.Model & mdash; Martensite (high strength chromium steel), good wear resistance and poor corrosion resistance.
