Q:How can I clean the stainless steel tube?
Stubborn or burned stains, can be mixed with baking soda and water, wipe with a soft cloth.
Q:How can the stainless steel tube eliminate stress?
Or artificial stress, method: stresses both ends of the steel pipe fixed by the mold, through high-frequency shocks, so that the internal stress relief of the steel pipe
Q:Comparison of ring type connection and argon arc welding of stainless steel pipe
Ring type stainless steel pipe connecting end design section of successive and sealing section shape was stepped through the hydraulic tool connection exerts a pressure on the radial deformation of the pipe, stable and sealed sections of Zuohuan extruded and its circumference concave, concave section into which the pipe with forced recess annular snap fastener
Q:How about stainless steel 2520 and 316?
316 stainless steel by adding Mo element, the corrosion resistance, and high temperature strength has greatly improved, high temperature can reach 1200-1300 degrees, can be used in severe conditions. Uses: marine equipment, chemicals, dyes, paper, oxalic acid, fertilizer and other production equipment; photography, food industry, coastal facilities, ropes, CD poles, bolts, nuts.
Q:Why can it stainless steel be put together with carbon steel tube?
An electronic passage formed by wire bonding or direct contact. The carbon in the carbon steel tube loses its electrons to the stainless steel tube and the surface is absorbed by the etchant.
Q:What kind of welding machine is used for welding thin stainless steel plate and stainless steel square tube?
1 mm thick enough, basically argon arc welding machine can, 0.2 thick stainless steel plate welding is not good ah, how have three or four points it can be positive or negative, only a few joints only, mainly to see the technology myself you, not what, the polishing wheel is on the line let's do it, you can buy a good quality of argon arc welding machine, the high price of the arc is stable
Q:316 stainless steel pipe wall mirror polishing, the smaller the roughness, the better.
Sanitary grade stainless steel tube and stainless steel sanitary pipe: phi 6 - 219mm * 0.5 - 5mm. The product is cold rolled by three roll tube mill and is polished inside and outside by degreasing and flat drawing. It is a seamless sanitary stainless steel pipe and stainless steel sanitary pipe finished product. The outer surface of the product is polished, the diameter and wall thickness tolerance of less than 0.02-0.05mm, the inner wall of the pipe roughness Ra is less than or equal to 0.6 m after Ra or 0.4-0.25 inner wall polishing m, sanitary stainless steel pipe and stainless steel pipe health features: inside and outside wall of polished, bright surface, very smooth, high dimensional accuracy, delivery status generally hard (micro magnetic), and widely used.
Q:Stainless steel pipe pickling ratio
Usage: apply proper amount of this product onto the surface of stainless steel to be processed, the thickness of 1~2 mm, 5-30 minutes or longer (by dirt, sheet materials and processing requirements), process the best brush a few times, the surface oxide skin, rust completely clean, with water (lime water or salt water better) rinse, avoid rust.
Q:SA-179 what kind of material is steel pipe?
Seamless steel pipe having a hollow cross section, used as a conduit for conveying fluids, such as pipelines for transporting petroleum, natural gas, gas, water, and certain solid materials.
Q:Stainless steel seamless steel tube, ordinary seamless steel pipe, which is good?
The general stainless steel tube is wear-resistant, high temperature resistance, corrosion resistance. Plain carbon steel seamless tubes resist pressure better than stainless steel.
