Q:What does "steel pipe SC" mean?
SC is an ordinary welded pipe, equal to water professional DN, SC is welded steel pipe concealed, general pipe wall is relatively thick, S represents pipe material, C represents laying mode, TC stands for wire pipe concealed, pipe wall is thinner.
Q:What is the production process of seamless steel tube?
The main production process for hot rolling seamless steel tube (the main inspection):Tube preparation and check delta to billet heating, heating, rolling, perforated pipe, steel pipe and heat treatment, diameter (minus) Delta to finished tube straightening, finishing and inspection of delta (nondestructive, physicochemical, Taiwan inspection and warehousing)
Q:What's the difference between a rectangular tube and a rectangular steel tube?
The classification of rectangular tube: steel pipe seamless steel pipe and welded steel pipe (tube) hot-rolled seamless tube, seamless tube, seamless tube, welded tube extrusion. The welded square pipe is divided into two parts:(a) according to the process of arc welding - resistance welding tube, square tube (high frequency and low frequency), welding square tube, welding square tube furnace (b) according to the weld - welded square tube, spiral welded pipe.
Q:Water, gas, steel pipes, thick steel wire means?
Often used in water, heating, gas, compressed air and vacuum lines. Can be used in pressure gauge pressure of 0.6 MPa (6 atm) steam pipe and condensate pipeline below, can also be used for conveying non erosive and non flammable and explosive media. Is divided into ordinary (working pressure is 1 MPa pressure gauge, 10) and strengthening (working pressure gauge is 1.6 MPa, 16 ATM) two. Galvanized white iron tube (galvanized iron tube). Non galvanized black iron pipe (black pipe).
Q:Which is more load-bearing, the same thickness of steel pipe and steel bar?
The magnitude of the axial force acting on the steel member is only related to three factors, namely, the strength of the material, the sectional area of A and the longitudinal stability factor of F.
Q:Welded and seamless steel pipe how to distinguish?
Different price:Because the production process of seamless steel tube is more complex, so the price is more expensive than a seamed steel pipe, and pipe joints mainly adopts steel (steel) two welded, fixed price, the most widely used are.
Q:Difference between cold rolled steel pipe and common steel pipe
1, from the dimension accuracy above, cold-rolled steel pipe size is good, high precision2. from the outward appearance, the surface of cold-rolled steel pipe is bright, and the surface of hot rolled steel pipe has obvious oxide skin or red rust
Q:What's the difference between seamless steel pipe and welded pipe?
The difference can be seen from the outward appearance that the welded pipe is welded by roll up.
Q:What time what time for gas pipeline steel pipe PE pipe
City network is generally medium, are generally. PE pipe high pressure pipe with building the required distance, is generally used around the high pressure pipe laying (high pressure gas supply capacity, and can play the role of peak shaving), the city zone by the supply voltage to the voltage, residential building regulation boxes of low voltage supply to the users.
Q:What quota is reserved for buried DN20 steel pipe?
If it is reserved for embedded pipe pre buried steel waterproof casing, set of waterproof casing steel production and installation is to set the quota items, if the outdoor installation of welded steel pipe buried steel casing pre quota items, if it is a reserved hole, then there is no need to set the quota items.
