Process lubrication → . Annealing → . Leveling → ⒍ fine cutting → ⒎ packaging → . Reach customers.
zAccording to the purpose，Products Show it can be divided into oil well pipe (casing，317L stainless steel pipeOnline consultation oil pipe and drill pipe)， pipeline pipe， boiler pipe， mechanical structure pipe， hydraulic prop pipe， gas cylinder pipe， geological pipe， chemical pipe (high-pressure chemical fertilizer pipe， petroleum cracking pipe) and marine pipe.
In order to prevent the occurrence of welding pores，Products Show the welding parts must be cleaned if there is rust， oil stain， the welding parts must be cleaned if there is rust， oil stain， etc.
Stainless steel pipe water supply pipe is a healthy， economic， sanitary and energy-saving water pipe. It is the best choice for both domestic and large engineering buildings. It is also frequently launched in the market. If you want to buy a stainless steel pipe water supply pipe with quality assurance， what should you choose?
Low temperature processing --- martensitic stainless steel is quenched from austenitizing temperature and then cooled to very low temperature to promote the quenching of martensite. It is suitable for stainless steel which is easy to produce retained austenite.
eAustenitic stainless steel heat treatment austenitic stainless steel commonly used heat treatment processes are: solution treatment stabilization treatment and stress relief treatment.
I — Martensite (high strength chromium steel)， equivalent to China Al () deep drawing steel. If it is necessary to ensure non aging property， add n at the end of the brand as spcen. Quenching and tempering code of cold-rolled carbon steel sheet and strip: annealing status is a，Products Show standard quenching and tempering is s， / hard is / ，317L stainless steel pipeOnline consultation hard is / hard is . Surface processing code: dull finish rolling is D， bright finish rolling is B. spcc-sd represents cold-rolled carbon sheet generally used for standard quenching and tempering and matt finish rolling. Another example is spcct-sb It refers to cold-rolled carbon sheet with standard quenching and tempering and bright processing and required to ensure mechanical properties.
mMIn addition to common scenes in life， stainless steel is also used in some high-end machinery fields， such as food industry， chemistry， medical devices， aircraft exhaust pipes
— The commonly used precipitation hardening stainless steel models， products and tens of millions of products are up to you to choose. It specializes in selling stainless steel plates，tisco stainless steel sheet,taigang stainless steel sheet,stainless steel sheet,stainless steel coil,stainless steel strip,stainless steel tube-TISCO Stainless Steel Co.,Ltd stainless steel coils， stainless steel belts and stainless steel tubes. The transaction is safe and secure. It is usually also called -% Cr and % Ni.
Process performance inspection: flattening test， tensile test， impact test， flaring test， hardness test， metallographic test， bending test and nondestructive testing (including eddy current testing， X-ray testing and ultrasonic testing).
AdministrationgAfter the pipeline is installed and the pressure test is qualified， it is better to wash with low chloride ion water and disinfect with .% potassium permanganate.
FModel & mdash; Except that the risk of weld corrosion of the material is reduced due to the addition of titanium， other properties are similar. Stainless steel decorative pipe， stainless steel pipe， series stainless steel pipe & mdash; Ferritic and martensitic stainless steel model & mdash; Good heat resistance， weak corrosion resistance， % Cr， % Ni.
Theoretical weight of stainless steel pipe: w = outer diameter - wall thickness x wall thickness x..
mRolled steel plate cold rolled steel plate according to surface characteristics summary of surface characteristics manufacturing method application silver white matte hot rolled to the specified thickness， and then annealed and descaled a rough and matte surface without surface gloss. Silver white cold rolled heat treatment and pickling D products are used for applications with lax surface requirements. The gloss of general materials and deep drawing materials is stronger than that after D treatment， the general material Ba is as bright as a mirror. There is no standard， but it is usually the surface processing of bright annealing， and the surface reflectance is very high. For building materials， ~ # (unit) abrasive belt is used for kitchen coarse grinding to grind building materials， The polishing surface obtained by grinding with ~ # abrasive belt in the middle of the kitchen is the same as that obtained by fine grinding. The polishing surface is polished with # abrasive belt. The ultra-fine grinding in the kitchen is polished with # abrasive belt. The luster is similar to that of Ba. It is generally used for grinding with # polishing wheel. It is used for construction. It is specialized in stainless steel plate， stainless steel coil and stainless steel belt， Stainless steel pipe quality assurance. New and old customers are welcome to consult during the preferential activities. HL hair line grinding in the kitchen is carried out by grinding materials with appropriate particle size for hair line grinding ( ~ #). There are many buildings and building materials close to mirror grinding. # rotary polishing wheel is used for grinding for art， mirror grinding for decoration， mirror grinding for mirror， For decoration according to the purpose， bridge steel plate， boiler steel plate， shipbuilding steel plate， armored steel plate， automobile steel plate， roof steel plate， structural steel plate， electrical steel plate (silicon steel sheet)， spring steel plate， special solar plate (Hairui special steel) are common Japanese brands in other steel plates for ordinary and mechanical structures.
