Q:How can galvanized steel pipe be connected with stainless steel pipe?
Welding methods are used to connect. Because galvanized pipe is in fact carbon steel pipe, so galvanized pipe and stainless steel pipe welding, in fact, carbon steel and stainless steel welding, welding of dissimilar materials.
Q:How much is 4 inches steel tube MM?
The nominal diameter of the 4 inch steel pipe is DN100, that is to say, the diameter of the center of the pipe wall is 100mm.
Q:What's the difference between a rectangular tube and a rectangular steel tube?
No difference, but your name is different, rectangular steel pipe, but can be divided into seamless rectangular steel pipe and welded rectangular, these two, in the material will also have a difference, I do not know how to help you
Q:What's the difference between hot dip galvanizing and cold galvanizing? Which kind of galvanizing method is good?
Cold galvanizing refers to the zinc plating, the coating is thinner, corrosion resistance is slightly worse, variable color. Environmental pollution.Hot dip galvanized by molten zinc ingots, the coating thickness can be adjusted, good corrosion resistance, and subsequent passivation, can be used for outdoor rust, long service life, some up to 20 years.
Q:What is DN50 for welded pipe?
Refers to the use of welded steel pipe made of DN50 steel pipe, refers to the inside diameter is 50mm, the market of common DN50 pipe also refers to the 2 inch pipe, standard pipe: 3.5mm thickness, pipe diameter 60mm, the weight of 4.88kg/m theory. DN50 seamless steel pipe, commonly used in the market, has two specifications: 57mm, 60mm, and if no special instructions, 57mm is commonly used. The outer diameter of the welded pipe is only 60mm this specification.
Q:Where is the difference between seamless steel pipe and welded pipe?
Seamless pipe pressure is higher, welded pipe is generally in 10 or so MPa, now welded pipe to do seamless processing.
Q:How long is the seamless tube?
Welded pipe is generally 6912 meters fixed length, seamless pipe on the market in general non fixed foot, but usually more than 6 meters
Q:What is the diameter of the steel tube DN20?
Usually the nominal diameter is nominal for cast iron pipe, steel pipe joints, concrete pipe pipe, seamless steel pipe does not use this notation (with diameter * wall thickness). With nominal diameter pipeline accessories, meaning with tube.
Q:Can stainless steel pipes spray black paint?
Yes, after painting, I usually touch hands and paint off in 2 years or so
Q:What does "1.5" steel tube mean?
DN refers to the nominal diameter of the pipe (also known as nominal diameter), all piping accessories in the piping system are numerically represented in order to distinguish the parts that are represented by threads or outside diameters. Nominal diameter is used as a reference, after rounding the figures, and processing numerical value is not exactly the same, nominal diameter can be expressed as metric mm, also can be used in English in.
