Formula for hydraulic test pressure of stainless steel welded pipe for weight calculation fluid (gbt-): where: P - test pressure, MPa; R - stress, taking yield point of %, MPa; s - nominal wall thickness of steel pipe, mm; D - Nominal outer diameter of steel pipe, mm.The back is blocked with blocking plate for ventilation protection; Only soluble paper or the combination of soluble paper and blocking plate is used for blocking ventilation protection; Use flux cored wire for backing TIG welding.Vigo,The cold rolled steel strip has good strength and yield ratio, and the hot rolled steel strip has good ductility and toughness.Model & mdash; The addition of sulfur improves the processability of the material.Aussersihl,CE--“ Code for design of cold formed stainless steel structural parts & rdquo; And & ldquo; jointly published by nidi and euro inox; Structural stainless steel design manual & rdquo; The design of structural parts for buildings with long service life and good integrity has been simplified.Pipeline direct drinking water has developed rapidly. With the development of national economy, Shenzhen, Shanghai and Chongqing, stainless steel pipe system is undoubtedly second to none. At present domestic high-grade hotels and public places have been equipped or are equipped with direct drinking water pipes.As long as the steel type is selected correctly and maintained properly, stainless steel will not produce corrosion, pitting, corrosion or wear. Stainless steel is also one of the high-strength materials in metal materials for construction. Because stainless steel has good corrosion resistance, it can ensure that the structural components can maintain the integrity of engineering design. Chromium containing stainless steel also integrates mechanical strength and high extensibility and is easy to wear The processing and manufacturing of parts can be full

Stainless steel pipe, which was produced and used in China at the end of the s, 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.The width of coiled material is variable, including mm.mm.mm.mm.mm.mm, etc. it can also be divided according to customer requirementsThe recrystallization temperature changes with the shape variable. When the shape variable is %, the recrystallization temperature drops to ℃, it needs to be kept warm for h, fully burned at ℃, and then water-cooled.Quality assurance,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.The back is blocked with blocking plate for ventilation protection; Only soluble paper or the combination of soluble paper and blocking plate is used for blocking ventilation protection; Use flux cored wire for backing TIG welding.All steel with openings at both ends and hollow sections and with a large ratio of length to section perimeter, can be called steel pipe. When the ratio of length to section perimeter is small, which belong to the category of pipe products.

During welding, the process of ventilation in advance and gas stop behind shall be adopted, and the adhesive cloth on the outside shall be torn off while welding. Because the blocking plate is composed of rubber and white iron sheet, it is not easy to be damaged, so this welding can well ensure that the inner side of the weld is filled with argon and its purity, so as to effectively ensure that the metal on the inner side of the weld is not oxidized and ensure the quality of weld backing welding.Work courses,Stainless steel pipe factory stainless steel products are widely used in hardware products, furniture, mechanical structure, mechanical accessories, precision medical instruments, fluid transmission pipelines, such as furniture, machinery medical oil, natural gas, water, gas, steam and other industries.Delivery status: to be delivered after heat treatment and leveling.When using this method,VigoStainless steel plate suction cup, 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.Vigo,There are three main reasons for oxidation of stainless steel: production process, 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,VigoStainless steel plate, stainless steel coil, when the oxide film is incomplete and discontinuous due to insufficient or negligent production process, the oxygen in the air will directly react with some elements in the product, resulting in the appearance of oxidation of the product.Editor's note on the causes of steel rusting: chloride ions exist widely, such as salt, sweat stains, seawater, sea breeze, soil, etc. stainless steel corrodes rapidly in the presence of chloride ions, even surpassing ordinary low-carbon steel. Chloride ions form complexes with Fe in alloy elements,VigoStainless steel 4K brightness plate, reducing the positive potential of Fe, and then being stripped of electrons and oxidized [].Model & mdash; Martensite (high strength chromium steel), good wear resistance and poor corrosion resistance.
