Stainless steel pipes and water transmission equipment for fluid transportation such as water and gas are advanced basic water purification materials in the world. They have strong anti-corrosion performance,Soledad-Diez-Gutierrez316L stainless steel pipe, which can not be compared with cast iron pipes, carbon steel pipes and plastic pipes.Production process of stainless steel welded pipe: raw material - strip - welded pipe - end repair - polishing - Inspection (spray printing) - Packaging - shipment (warehousing) (decorative welded pipe).Soledad-Diez-Gutierrez, there are different tolerances for seamless hot expanded pipe, seamless cold rolled pipe and welded pipe according to different dimensions. For example, for hot expanded pipe with diameter less than mm when the thickness is mm and less, the upper limit tolerance of thickness is %; If the standard of stainless steel pipe is Chinese standard, according to the tolerance of stainless steel pipe for fluid transportation in gbt, the tolerance here is the tolerance when ordering according to the nominal thickness; According to the manufacturing method, the thickness standard of stainless steel pipe is divided into hot rolling and cold rolling, including thin plate with thickness of .-mm and thick plate with thickness of -mm. The specific gravity of stainless steel pipe is . The weight = specific gravity of length and width of thickness, and the weight of plate with thickness of stainless steel pipe of mm = m m = kg m (length) m (width) . M (thickness) (specific gravity) = . tons (weight)Stainless steel pipe, which was consumed and used at the end of the s, is a rebirth group emerging in today's pipe range. It has been widely used in the construction of water supply and direct drinking water pipelines. Stainless steel pipe is durable and has been recognized by the engineering community, and relevant parties are starting from reducing wall thickness and money so as to facilitate further implementation. In order to promote stainless steel pipe, since the s, China has started to reduce wall thickness and cost; High diameter to wall ratio and high precision & rdquo; The technical effect of stainless steel pipe makes the stainless steel pipe lose its application and expand quickly. There are various connection modes of stainless steel pipes. The rare types of pipe fittings include contraction type, compression type union type, push type, push thread type, socket welding type, union flange connection, welding type and derivative series connection mode combining welding with traditional connection. These connection methods have different application ranges according to their principles, but most of them are convenient, nitrile rubber and EPDM that meet the requirements of national specifications, which eliminates the worries of users. In the construction of water supply pipe system, due to the glorious history of galvanized steel pipe, all kinds of new plastic pipes and composite pipes have been lost and developed rapidly, but they are far from fully meeting the needs of water supply pipe system and the national requirements for drinking water and related water quality. In direct drinking water, stainless steel pipe system is undoubtedly one of the best. At present, hotels and public places at the international level have been equipped or are equipped with direct drinking water pipelines. In many cases, stainless steel pipe has more advantages, especially the stainless steel pipe with wall thickness of only . ~ mm has the characteristics of safety, reliability sanitation, environmental protection, economy and applicability in high-quality drinking water system, energy-saving and environmental protection pipes with good comprehensive function of water supply, but also a very competitive water supply pipe, which will play an unparalleled role in improving water quality and improving people's living standard.Pitalito,Deburring: after the pipe is cut off, the burr shall be removed to avoid cutting the sealing ring.When hoisting stainless steel pipes, 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.The welding of stainless steel pipe is usually composed of backing welding, which is not only related to the quality of engineering

Good ductility, used for forming products. It can also be machined to harden rapidly. Good weldability. Wear resistance and fatigue strength are better than stainless steel.Corrosion resistance most stainless steel products require good corrosion resistance. Stainless steel pipe is similar to class I and II tableware, kitchen, water heater, water dispenser, the solution is to drain, wash and dry, and determine the weight loss to determine the degree of corrosion. the responsibility of the calender is that the annealed steel strip is blackened, the furnace liner is perforated, and ammonia leakage will cause rust. . The responsibility of the steel plant is that the peeling and trachoma of the steel strip will cause rust. Substandard materials will cause rust. the responsibility of the calender is that the annealed steel strip is blackened,Soledad-Diez-GutierrezStainless steel Ba pipe, the furnace liner is perforated, and ammonia leakage will cause rust. . The responsibility of the pipe manufacturer: the welds in the pipe manufacturer are polished rough, which will cause rust.demand,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.The back is not protected by argon, and the flux cored wire + TIG process has been applied in China for several years. Flux cored wires such as et-elt-et-elt-t-et-elt- have been produced and applied to field welding, and good economic benefits have been obtained.Only soluble paper or the combination of soluble paper and blocking plate is used for blocking ventilation protection (i.e. solid core welding wire + TIG + water-soluble paper)

Measures to improve the welding quality of stainless steel pipe in order to ensure that the outer surface of stainless steel pipe is not damaged and purified, the maintenance of stainless steel pipe should be strengthened in each process of consumption, mainly including the following three aspects: the processing and consumption of stainless steel pipe should have a special consumption workshop (wood board is well used) , avoid the machining platform of austenitic stainless steel and carbon steel or solid overhead.Honest serviceSection shape stainless steel pipe can be divided into round pipe and special-shaped pipe according to the section shape. Special shaped tubes include rectangular tubes, elliptical tubes rhombic tubes, hexagonal tubes, tools and mechanical parts. Compared with circular pipe, special-shaped pipe generally has large moment of inertia and section modulus, and has large bending and torsion resistance, which can greatly reduce the structural weight and save steel.Carbon structure delivery status: delivered in heat treatment (annealing, normalizing,Soledad-Diez-Gutierrez201 cold rolled stainless steel strip, tempering after normalizing, high temperature tempering).Stainless steel pipe is durable and has been recognized by the engineering community, and relevant parties are starting from reducing the wall thickness and lowering the grid, so as to facilitate further development. In particular, the price of stainless steel pipe is not high, so the supporting connection, the reliability and price of pipe fittings are the main factors determining its development. Domestic developers have independently developed connection technology and pipe fittings in Sichuan, Guangdong, Zhejiang, Jiangsu and other places, which is a promising pipe. The Ministry of construction and relevant departments also attach great importance to this new type of pipe. According to China technology market management promotion center and gksz [] No. document on Application & ldquo; High diameter to wall ratio and high precision stainless steel medium and high pressure water supply pipes and supporting fittings and special technology & rdquo; It is learned from the notice that the application of stainless steel pipe technology and product is of great significance to improve the grade of modern buildings in China and improve and ensure the water quality of water supply.Soledad-Diez-Gutierrez,Meet the needs of architects and structural designers.High frequency welding high frequency welding: with relatively high power supply, it can reach a higher welding speed for steel pipes with different materials, outer diameter and wall thickness. Compared with argon arc welding, it is more than ten times its high welding speed. Therefore, stainless steel pipes for common use have a higher consumption rate. Due to the high speed of high frequency welding, it is difficult to remove burrs in welded pipes. At present, high frequency welding Welded stainless steel pipe can not be borne by chemical and nuclear industries, which is also one of the reasons.There is a bright future for domestic substitution for imported stainless steel pipes. Since the s, China has solved the problem of reducing wall thickness and cost; High diameter to wall ratio and high precision & rdquo; The technical problems of stainless steel pipe make the stainless steel pipe applied and developed rapidly. If a pipeline can be fully applied, localization is indispensable. At present, some domestic have the ability to produce and further develop stainless steel pipes and fittings.
