　　≥TS（Mpa）Welding and the whole continuous casting process of stainless steel pipe fittings is completed. Series & mdash; Heat resistant chromium alloy steel.Hyvinge, high frequency preheating plus three torch argon arc welding, high frequency preheating plus plasma argon arc welding. The progress of combined welding is very significant. As for the combined welding of steel pipe with high-frequency preheating, the weld quality is equivalent to the conventional argon arc welding and plasma welding, the welding operation is complex, and the whole welding is easy to complete automation. This combination is easy to connect with the existing high-frequency welding equipment, with low investment cost and good benefit.Bergamo,Model & mdash; Commonly used precipitation hardening stainless steel model, usually also called -; %Cr,%Ni.Deburring: after the pipe is cut off, the burr shall be removed to avoid cutting the sealing ring.The experimental ice load of concrete decorated stainless steel pipe is the highest in the cold area

Martensitic stainless steels typical martensitic stainless steels include Cr ~ Cr and Cr, which have good processing properties. Deep drawing, bending, crimping and welding can be carried out without preheating. Crl does not require preheating before cold deformation, while crcr is mainly used to make surgical and wear-resistant parts of medical instruments; crl can be used as corrosion-resistant bearings and tools.h chemical composition carbon C: Manganese Mn: silicon Si: chromium Cr: nickel Ni: phosphorus P: sulfur s: niobium NB: h stainless steel Name: austenitic stainless steel standard: aisastm model: huns No.: Note: a single value is a high value unless otherwise indicated; when used in some pipe making processes,Hyvinge420J2 stainless steel plate, the nickel content of some models of austenitic stainless steel must be slightly higher than that shown in the table; optional High TA content is .%; high content is .%; high content is the basic characteristics of stainless steel, with high temperature strength and high temperature plasticity excellent oxidation resistance and corrosion resistance, good structural stability, uniform chemical composition, good processing performance and welding performance high dimensional accuracy and surface quality. causes of rust when brown spots appear on the surface of stainless steel They were greatly surprised: & rdquo; stainless steel will not rust. Rust is not stainless steel. There may be something wrong with the steel quality. & rdquo; in fact, this is a one-sided wrong view of the lack of understanding of stainless steel. Stainless steel will also rust under certain conditionsHigh frequency welding high frequency welding: with relatively high power supply, it can reach a higher welding speed for steel pipes with different materials,Hyvinge1018 stainless steel plate, 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.High quality brand,The numbering rules adopt element symbols; Pinyin,Hyvinge201 stainless steel strip factory, open hearth steel: p; Boiling steel: F; Killed steel: B; Class a steel: a; T: special GCr: ball.Low temperature processing of stainless steel pipe --- martensite series stainless steel is quenched from austenitizing temperature and then cooled to very low temperature to promote martensite quenching. It is suitable for stainless steel easy to produce residual austenite.Application field: launch the market plan of stainless steel pipe in the target market of new products, such as stainless steel kitchen equipment.

Production process of stainless steel welded pipe: raw material - strip - welded pipe - end repair - polishing - Inspection (spray printing) - Packaging - shipment (warehousing) (decorative welded pipe).Which one is better,In order to ensure the appearance quality of continuous casting slab, select appropriate maintenance slag; During continuous casting, the vibration marks formed on the surface of continuous casting slab due to the vibration of mold shall be; Electromagnetic stirring must be used in continuous casting of ferritic stainless steel pipe fittings.Stainless steel pipe is a common material in stainless steel, with a density of GCM, which is also called stainless steel in the industry. High temperature resistance of ℃, with the characteristics of good processing performance and high toughness, it is widely used in industry, furniture decoration industry and food and medical industry.Construction materials shall be prepared and delivered to the site according to the data scheme, and shall be supplied according to the scheme.Hyvinge,Marking: in order to make the steel pipe complete the socket of the pipe fitting, the length must be marked and marked at the pipe end.Model & mdash; Cheap model (British and American), usually used as automobile exhaust pipe, which can be used to determine the hardness of very thin metal materials and surface layers. It has the main advantages of Brinell and Rockwell methods and overcomes their basic disadvantages, but it is not as simple as Rockwell method. Vickers method is rarely used in steel pipe standards.
