Q:Stainless steel heating oven tube after treatment is heating blue will not be red?
Unless they are not stainless steel, or they control the temperature of the heating tube, the continuous heating will be red, after all, the material has not changed. If the outside of the heating tube is ceramic, it won't be red.
Q:The difference between galvanized steel pipe and stainless steel pipe
Plastic pipe, plastic pipe, also known as plastic composite pipe, with steel pipes for the matrix, by spraying, rolling, leaching, absorption process in steel tube (bottom tube) steel plastic composite pipe internal surface is welded with a layer of plastic coating or plastic anti-corrosion layer on the inner surface and the outer surface of the weld. The plastic pipe has excellent corrosion resistance and small friction resistance. Delivery of epoxy resin coated steel pipe is suitable for water, water, water, oil, gas and other medium, PVC plastic pipe for drainage, water, oil, gas and other media delivery.
Q:What factory uses industrial stainless steel tube to be more?
For equipment manufacturing and maintenance, etc., the annual consumption of stainless steel pipe more than 20000 tons. Such industries mainly use sanitary or antibacterial grade stainless steel tube.
Q:Does stainless steel pipe belong to hardware?
Belong to. Hardware: refers to gold, silver, copper, iron, tin, five metal materials called. Stainless steel pipe is a kind of hollow long strip round steel.
Q:Comparison of ring type connection and argon arc welding of stainless steel pipe

Decorative tubes, then more specifications. Our factory has the smallest 9.5MM, the largest to see how big you can, directly with the industrial pipe to polish it
Q:Disadvantages of stainless steel tubes
Aluminum plastic composite pipe is a kind of pipe material that is more popular at present. Because of its light weight, durability and convenient construction, it is more suitable to be used in home decoration. The main drawback is that when used as a hot water pipe, due to long-term thermal expansion and cold contraction, it will cause the wall of the pipe to be dislocated so as to cause leakage.
Q:How thick is the 3 stainless steel tube?
3 thicknesses representing 3 mm wall thickness
Q:316 stainless steel pipe wall mirror polishing, the smaller the roughness, the better.
Steel pipe is purchased separately, and then polished to find manufacturers alone, can meet the requirements,The cost is very high. To tell you the truth, I don't know.Specializing in sanitary stainless steel tube, stainless steel tube, precision sanitary stainless steel tube and stainless steel tube precision tube production and sales, the main material: stainless steel material: 0Cr18Ni9 (304 stainless steel tube) and 00Cr19Ni10 (304L stainless steel tube (316), stainless steel tube), 00Cr17Ni14Mo2 (GB 316L stainless steel tube), the products are widely used in instrumentation pharmaceutical machinery, food machinery, auto parts, pneumatic components, beverage, beer, drinking water, air purification and biological engineering and other fields.
