According to the purpose, oil pipe and drill pipe), pipeline pipe, boiler pipe, mechanical structure pipe,CrucesStainless steel parts, hydraulic prop pipe, gas cylinder pipe, geological pipe, chemical pipe (high-pressure chemical fertilizer pipe, petroleum cracking pipe) and marine pipe.Brinell hardness in stainless steel pipe standards, Brinell hardness is widely used, and the hardness of the material is often expressed by indentation diameter, which is intuitive and convenient. However it is not suitable for steel pipes with hard or thin steel.Cruces,  — Common precipitation hardening stainless steel models, products and tens of millions of products are up to you to choose. Professional stainless steel plate, stainless steel coil, stainless steel belt and stainless steel pipe are safe and secure. They are usually also called -% Cr and % Ni.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.Samitah,When installing and welding the fixed port of stainless steel pipe it is difficult to vent on the inner side, water-soluble paper + blocking plate can be used for blocking. That is and some sides are easy to be blocked. In this case, the difficult to vent and bad blocking plate side can be blocked with water-soluble paper, including the chemical fertilizer industry, has a great demand for stainless steel pipes. Stainless steel pipes are mainly used in this industry, including, , l, etc., with an outer diameter of about ¢ - ¢ and a wall thickness of about mm-mm (generally medium and low pressure transmission pipes with a specification of more than & phi; mm). The specific application fields are: furnace pipes material transmission pipes, heat exchanger pipes,Cruces321 stainless steel strip, etc.Model & mdash; It has better temperature resistance.

Series & mdash; Heat resistant chromium alloy steel.The surface of the steel strip in the state of supply shall be rough or bright.When using this method, it should be noted that the water-soluble paper should be double-layer and must be pasted well, otherwise it is easy to cause damage and fall off of the water-soluble paper, resulting in loss of argon protection of the inner weld and oxidation, resulting in cutting of the weld junction and re welding, 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.Online consultationAt 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, it is necessary to pay special attention when using at low temperature. As a way to improve the impact toughness of ferritic series stainless steel, high purification process can be considered. With the help of C and N level, the embrittlement temperature is in the range of - ℃ to - ℃Inspection: after crimping, public slings, such as hoisting belt and public collet number, shall be used. It is strictly prohibited to use steel wire rope to avoid scratching the surface; and when hoisting and placing, it shall prevent scratching caused by impact and collision. If there are surface scratches, electric arc traces and surface purification in the process of transportation, storage and processing, it must be completely cleaned, polished with an angle grinder, and then polished Polishing with optical sheet or metallographic sandpaper.Click to view,. Domestic wce cerium tungsten electrode is used for electrode data. The shape and diameter of the end of cerium tungsten electrode have a great impact on the fluctuation of welding process and weld formation.◆ stainless steel and alloy tool steel (C content is expressed in thousandths), such as thousandth of CrNi (i.e., stainless C & LE); .%, such as CrNi, ultra low carbon C & le; .% if the international stainless steel mark, the American Iron and Steel Institute uses three digits to mark various standard grades of malleable stainless steel. Among them, austenitic stainless steel is indicated by numbers of and series,CrucesStainless steel plastic coated pipe, some common austenitic stainless steels are marked with , , and , ferritic stainless steels are marked with and , martensitic stainless steels are marked with and C, duplex (austenitic ferrite), stainless steels, precipitation hardening stainless steels and high alloys with iron content less than % are usually named by patent name or trademark.In the building water supply pipe system, due to the end of the glorious history of galvanized steel pipe, various new plastic pipes and composite pipes have developed rapidly, but various pipes still have some deficiencies in varying degrees, which are far from fully meeting the needs of water supply pipe system and the national requirements for drinking water and related water quality. Therefore, relevant experts: building water supply pipes will eventually return to the era of metal pipes. According to foreign application experience, stainless steel pipe is recognized as one of the pipes with good comprehensive performance in metal pipe.Cruces,AUSTENITIC FERRITIC duplex stainless steel. It has the advantages of both austenitic and ferritic stainless steel, and has superplasticity. Martensitic stainless steel. High strength, but poor plasticity and weldability.Flux coated welding wire (self shielded welding wire) shall be used for backing TIG welding.Stainless steel pipes can be divided into CR series ( Series), Cr Ni series ( Series), Cr Mn Ni series ( Series) and precipitation hardening series ( Series). Series & mdash; Cr Ni Mn austenitic stainless steel series & mdash; Cr Ni austenitic stainless steel.
