Q:Are the welded and galvanized tubes the same weight?
There should be no difference in the weight of the same specifications for the welded pipe and galvanized pipe. The slight difference is that the galvanized pipe should be pickled before galvanizing and must digest some iron and then galvanized. The difference depends on the difference in the process. So the theoretical calculations are the same.
Q:How long are the seamless tubes? Are they six meters long?
The length of the seamless tube is 3000~12000mm, including 6 meters.
Q:How to descaling galvanized steel pipe?
If the substrate is rusty, rust removal can be removed by acid leaching. If the coating is rusted, it can also be dipped in acid, but this will also remove the coating and make the base material more susceptible to rust, preferably by re plating and passivation
Q:ASME seamless tube how to express, what is the form, I did not find on the ASME, thank God!
You can refer to the ASME B31.10, such as the requirements for the SA106GRB seamless steel tube outer diameter of 168.3 x 7.11, specifications can be marked as NPS6 SCH40 SMLS, the real mark should include pressure steel pipe factory name or trademark, and the material level, specifications, standards, wall number, batch number, pressure test (if any), NDE detection (if any)
Q:What are the uses of welded steel pipes?
The spiral submerged arc welded pipe (SY5036-83) for the delivery of pressurized fluid is made of hot rolled steel strips for tube billets, often spirally formed, welded by double submerged arc welding and used for the transmission of pressurized fluid. The steel pipe has strong pressure bearing ability and good welding performance. After a rigorous scientific examination and test, it can be used safely. The utility model has the advantages of large caliber of the steel pipe, high transmission efficiency, and investment in laying pipelines. Mainly used in the transportation of petroleum and natural gas pipelines.
Q:What's the difference between the fastener type steel pipe scaffold, the floor type steel pipe scaffold and the overhanging type steel pipe scaffold?
Classification is not the only way, fastener type steel pipe scaffolding is divided by force, and the latter 2 are classified according to the structure.
Q:Does seamless steel tube have a bend of 135 degrees?
In engineering, it is usually marked as "45 elbow" and has no "135" mark. The angle of the elbow is acute, so there will be no more than 90 degrees elbow.Elbow is a common connecting pipe used in plumbing and heating. It is used for the connection of the bend of pipe, and is used to change the direction of pipe.
Q:What's the use of steel pipe?
(processing workshop of Tianjin steel pipe company as a result of the steel pipe truss structure, the actual steel saving up to 42.9%), with a steel pipe manufacturing highway bridge can not only save steel, simplify the construction, but also can greatly reduce the coated area, saving investment and maintenance costs.
Q:304 stainless steel tube with the diameter of 25*2-3 is what mean
304 stainless steel tube with the diameter of 25*2-3 said: material for 304 (the equivalent of the American brand, Chinese numbered S30408 stainless steel or 06Cr19Ni10 stainless steel), diameter (OD) for 25mm, for the seamless steel pipe wall thickness of 2 to 3mm.
Q:How seamless steel tube is formed?
Overview of two kinds of steel pipe process:1, cold drawing (rolling) seamless steel pipe: round tube to heating to perforation, annealing, pickling, leading to oil (copper), multi pass drawing (Leng Zha), the blank pipe, heat treatment, straightening, pressure test (testing), marking and warehousing.2. Hot rolling (extrusion seamless steel tube): round tube billet, heating, piercing, three roll cross rolling, rolling or extrusion, removal of pipe, sizing, reducing (diameter or reducing), cooling, blank tube, straightening, water pressure test (or flaw detection), marking and warehousing.
