Q:What is the diameter of the steel tube DN20?
Pipe installation without conversion, because in the same standard in the same diameter connecting dimensions of the same nominal pressure level of the same, and the same material have the same diameter, the nominal diameter of the purpose is to facilitate connectivity
Q:Difference between seamless steel pipe and welded pipe
Welding pipes can be used in water pipelines, gas pipelines, heating pipes, electrical appliances, pipelines and so on.
Q:How to perform nondestructive inspection of steel tubes
The detection principle is based on the ferromagnetic material is magnetized in a magnetic field, discontinuity materials and products (defects) produce leakage magnetic field, magnetic powder adsorption (or detecting) and appear (or on the instrument display). Therefore, this method can only be used for the inspection of the surface or near surface defects of ferromagnetic materials or products.
Q:D108*4 what does "D108" mean by seamless steel tubes? What does "*4" mean?
D108: refers to the outer diameter of 108mm;4: refers to the wall thickness of 4mm.
Q:What's the difference between a cracked carbon steel tube and a liquid carbon steel tube?
If the material is the same, the process is different from the test.
Q:How to make the magnetic steel, can be like a magnet?
Of course, not all materials can be magnetized, austenitic stainless steel will not do.
Q:Is the diameter of the steel tube indicated by the outer diameter by the wall thickness or by the inside diameter by the wall thickness?
Seamless steel pipe specifications are: outer diameter, wall thickness, material. Three of these reflect its main features.Welding pipe specifications are: nominal diameter (internal diameter), galvanized or non plated
Q:Can seamless steel pipe and ordinary steel pipe be welded?
Seamless steel tube branch and seamed two, seamed steel pipe welding is formed, all two can be welded together, if you do not allow the use of seam tube cannot connect.
Q:How do you solder purple copper plate and steel tube?
When the copper pipe and the size is not too large, such as 10 mm below the pipe welding, brazing is suggested, with brass solder, such as Wei Odin 201 solder, with supporting solder paste, with a neutral flame welding, the copper plate is heated to about 800 degrees, and then use the solder with 201 Wei Odin 201-F in solder welding, welding wire with melt molding.
Q:The outer circle of a seamless steel pipe 50 head into the outer circle of the 40 to close
That is, according to the production process of different classification, different from hot rolling (expansion) pipe. In the process of expanding the tube or raw material tube, it is processed by multiple cold drawing, usually on single chain or double chain cold drawn machine of 0.5 ~ 100T. Cold rolled steel pipe (DIAL) in general, steel pipe for low and medium pressure boiler tube, high-pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, oil cracking tube, machining pipe, thick wall pipe, small diameter and cold drawn steel tube also includes other tubes, carbon thin-walled steel, alloy thin-walled steel pipe, stainless steel pipe, special-shaped wall steel pipe. The outside diameter of cold drawn steel tube wall thickness to 6mm, to 0.25mm, to 5mm diameter thin-walled tube wall thickness is less than 0.25mm in size, accuracy and surface quality were significantly better than the hot (expanding) tube, but by the process control, its diameter and length are limited.
