Q:What are the specific differences between flexible pipes and rigid pipes?
Structurally:A rigid waterproof sleeve is welded with a water stop ring outside the steel pipe;The flexible waterproof casing pipe is welded on the outside of the 3 side wing ring, 4 screw buckle, inside a welding piece with a rubber ring, the outside and do a flange, with 4 double head bolt, welding a steel pipe, the pipe installed, the flange is installed. The screw fastening, tightening the apron is bigger, more Water Leakage, generally in the waterproof requirements of relatively high places, such as the pool of water.
Q:ASME seamless tube how to express, what is the form, I did not find on the ASME, thank God!
Seamless steel pipe, welded steel pipe, then its means of expression is: nominal diameter refers to the outer diameter (diameter * wall thickness), the unit is mm. [for example, seamless steel tubes of phi 32 * 3. It means that the nominal diameter (outside diameter) is seamless steel pipe of phi 32mm and wall thickness 3mm.
Q:There are multiple welded galvanized steel pipe outer diameter 108mm wall thickness 4mm length of 6 meters
Formula for calculating weight of welded steel pipe:Kg/m= (outside diameter mm-, wall thickness mm) * wall thickness mm*0.02466= (108-4) *4*0.02466=10.26 kg / MBecause of galvanizing, the weight is heavier than that of ordinary welded pipe 3%~6%.Therefore, the length of 6 meters galvanized steel pipe weighs about 10.26*6*1.06=65 kilograms
Q:What are the uses of seamless steel tubes?
Compared withsteel and roundsteelinsolid, flexural torsional strength in the same time, the weight is light, is a kind of economic section steel, widely used in the manufacture of structural parts and mechanical parts, such as the oil pipe, automobile transmission shaft, the bicycle frame and steel construction with scaffold with steel pipe manufacturing ring parts can be improved the utilization rate of materials, simplify the manufacturing process, material saving and working hours, such as rolling bearing ring, Jack and so on, has been widely used in steel pipe manufacturing.
Q:How can two smooth steel pipes be joined? The size of the two pipe is different (except for welding)
Butt fastener: used for connecting two steel pipe jointsThin-walled stainless steel pipe, the national standard consists of three parts, respectively on the thin stainless steel pipe connection, the sealing ring of raw materials of various specifications of O type thin wall stainless steel pipe diameter and wall thickness of pipe and rubber have clear requirements, in order to ensure the quality of the whole pipeline, pipeline safety and guarantee system durability. The connection mode is clamp type and ring type.
Q:20# seamless steel pipe and seamless steel pipe 20G what is the difference?
20#: low carbon steel seamless steel pipe, carbon steel is generally divided into low carbon steel, medium carbon steel and high carbon steel three, 45# steel in carbon steel, low carbon steel is lower than 45#, 45# is higher than that of high carbon steel, seamless steel pipe, such as no special requirements, using 20# seamless steel tube. 20# seamless steel pipe material is 20# steel, the strength is slightly higher than 15#, very little quenching, no temper brittleness. Cold plastic deformation and for bending, rolling, bending and hammer arch processing, arc welding and contact welding welding performance is good, when the thickness is small, prone to strict requirement of shape crack or complex shape parts. The cold or normalizing state of the cutting process is better than that of the annealed one. It is generally used to make workpieces with little stress and high toughness.
Q:What is the difference between hot dip galvanized steel pipe and galvanized steel pipe?
The difference between the process is that the hot dip galvanized pipe is dipped in the molten zinc bath and the galvanized pipe is plated with a metallic surface by means of unidirectional current in the plating bath. Hot plating process is fast, the coating is thick and consumes more zinc. Ordinary galvanized slow speed, thin coating.
Q:What steel pipes are buried for outdoor heating pipes? Seamless or welded tube? Are there any rules for specific countries? Can use the seamed tube?
The pipe material of heating pipe network should be designed according to the requirement. When the design is not specified, the following requirements shall be met:1 when the pipe diameter is less than or equal to 40mm, welded steel pipe shall be used.2 when the pipe diameter is 50 ~ 200mm, welded steel pipe or seamless steel pipe shall be used.3 when the pipe diameter is greater than 200mm, spiral welded steel pipe shall be used.
Q:Who knows what is the difference between double submerged arc welded pipe and longitudinal submerged arc welding?
Double submerged arc welding is also a kind of longitudinal submerged arc welding.
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.
We has nine sets of machine unit for Φ219-Φ2850 of SAWH steel pipe with an annual production capacity of around 260,000 tons, two sets of SAWL production lines: one with Φ1422 maximum and one Φ813 maximum with an annual production of 200,000 tons, two sets of machine unit for Φ168 maximum and Φ508 maximum HFW steel pipe with an annual production volume of around 160,000 tons, four sets of machine unit of square and rectangle pipe for the size of 200×200, 400×400, 250×250, 300×300 with an annual production capacity of around 140,000 tons and two sets of machine unit for internal and external coating with an annual production capacity of 2,000,000 sq.meters.
