Production process of stainless steel pipe A. preparation of round steel; b. Heating; c. Hot rolling perforation; d. Cutting head; e. Pickling; f. Grinding; g.; h. Cold rolling; i. Degreasing; j. Solution heat treatment; k. Straightening; l. Pipe cutting; m. Pickling; n. Finished product inspection.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, storage and processing electric arc traces and surface purification in the process of transportation, polished with an angle grinder,In order to obtain seamless pipes with smaller size and better quality, cold rolling cold drawing or a combination of both must be used. Cold rolling is usually carried out on a two high mill. The steel pipe is rolled in an annular pass composed of variable section circular groove and fixed conical plug. Cold drawing is usually carried out on a single chain or double chain cold drawing machine of . ~ t.Austenitic stainless steel. It contains more than % chromium, about % nickel and a small amount of molybdenum, titanium, nitrogen and other elements. Good comprehensive performance and resistance to corrosion of various media.Larmani hat,Rockwell hardness the Rockwell hardness test of stainless steel pipe is the same as Brinell hardness test. The difference is that it measures the depth of indentation. Rockwell hardness test is widely used at present, and HRC is second only to Brinell hardness Hb in steel pipe standards. Rockwell hardness can be used to measure metal materials from very soft to very hard, which makes up for the disadvantage of Brinell method, It is simpler than Brinell method and can read the hardness value directly from the dial of the hardness machine. However, due to its small indentation, the hardness value is not as accurate as Brinell method.The surface resistance is less than mb; Wear protection; Scalable; Excellent chemical resistance; Good alkali metal and acid resistance; Strong toughness; Flame retardant.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.

Austenitic stainless steel. It contains more than % chromium, about % nickel and a small amount of molybdenum, titanium, nitrogen and other elements. Good comprehensive performance and resistance to corrosion of various media. identification number and indication use international chemical element symbols and national symbols to indicate chemical composition. For a long time, stainless steel plate, stainless steel coil, stainless steel belt and stainless steel pipe have complete products, excellent quality and favorable price. Use letters to indicate composition content: for example, the United States, Japan, series, series series; the serial number is composed of Latin letters and order,Patos-FshatStainless steel welded pipe manufacturer, which only indicates the purpose.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, which can not be compared with cast iron pipes, carbon steel pipes and plastic pipes.average method, & mdash; high strength cutting tool steel, with slightly higher carbon content, can obtain higher yield strength after appropriate heat treatment, and the hardness can reach hrc. It is one of the hard stainless steels. A common application example is & ldquo; shaving blade & rdquo;. There are three common models: C and f (easy processing type).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 domestic prospect is promising, and there is a large demand for building water supply pipes. According to the 'Ninth Five Year Plan' of construction and the outline of long-term objectives in , the demand for each pipe is ~ km from to , including km of cold and hot water pipes in residential construction areas. Some people believe that the development of stainless steel water pipes is of great significance to improve the grade of modern urban buildings.

Inspection: after crimping, check the crimping size with a special gauge.Work courses,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.Performance supplement: main components: cr-ni-mo-.n; national standards: NAS juns S / sdin / en astm a, ASME sa-; mechanical properties: tensile strength: & sigma; B & Ge; mpa; elongation: & Delta; & Ge; %; typical working conditions: % dilute, below ℃, annual corrosion rate & amp; lt; .mm; supporting welding wire: er. Weight (kg) = length (m) * width (m) * thickness (mm) *Density value specific gravity of stainless steel: ● chromium stainless steel is t / m ● chromium nickel stainless steel is t / m ● iron is T / m. Theoretical weight calculation formula of stainless steel plate: Steel theoretical weight length (mm) & times; width (mm) & times; thickness (mm) & times; density value = weight (kg) Stainless steel plate, stainless steel, duplex stainless steel, stainless steel material,Patos-FshatStainless steel water supply pipe, Swedish stainless steel brand. The differential yield strength between duplex stainless steel plate and austenitic stainless steel plate is twice that of ordinary austenitic stainless steelVarious welding methods of combined welding stainless steel welded pipe have their own advantages and disadvantages. Combined welding methods include argon arc welding plus plasma welding, high-frequency welding plus plasma weldingPatos-FshatW = (outer diameter wall thickness) & times; wall thickness & times; . = KGM (weight per meter).There are mechanical, it is not easy to remove the scale on the surface and make the surface highly clear and flat. Generally, the removal of the scale of stainless steel pipe should be carried out in two steps, the first step is pretreatment and the second step is ash removal.During welding, the process of ventilation in advance and gas stop behind shall be adopted,Patos-FshatStainless steel sanitary pipe manufacturer, 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.
