- Inquire about price/MOQ

Q:Can the KBG25 steel tube hold 4 six types of cables?
Over five types of cables, the outer cross section is about 24 square millimeters, over six types of network cable for the outer cross section of about 35 square millimeters, so 35*4/490=28.57%, far more than 20%. Therefore, according to the norm, only 3 super six categories can be worn. If the distance is short and the joint is not enough, it can be laid like this, but it does not conform to the construction standard
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:What are the lengths of scaffold steel tubes?
Scaffold tubes are our name for materials used to build scaffolding, because most scaffolding uses tubular bamboo or steel tubing. Bamboo and other bamboo is for a long time in the use of the scaffolding tube, but due to lack of safety and durability, now only in rural and urban area construction is lagging behind some of the home building small building has been used. The modernization construction, the most commonly used type of scaffolding pipe is steel pipe, the scaffolding should not only meet the demand of workers, but also to meet the characteristics of scaffolding firm and durable, so tough hard steel is the best choice. The selected steel pipe generally requires smooth surface, no cracks, no bending, no rust, and meet the relevant national standards.
Q:Does seamless steel tube have a bend of 135 degrees?
Other name: 90 degree elbow, right angle bend, love bend, punching elbow, pressing elbow, mechanism bend, welding elbow, etc..Usage: connect two pipes with same nominal diameter or different pipe, make the pipe bend at 90, 45, 180 degrees and various degrees.Bending radius is less than or equal to 1.5 times the diameter of the elbow. It is 1.5 times larger than the pipe diameter and belongs to the elbow
Q:What's the use of steel pipe?
Steel pipe is not only used to transport fluid and powder solid, exchange heat energy, and manufacture mechanical parts and containers, but also is an economic steel. It can reduce weight and save 20 to 40% of metal by using steel pipe to make building structure, network frame, prop and mechanical support. Moreover, it can realize factory mechanization construction. (
Q:Seamless steel tube 89X4 meters, how heavy?
Generally seamless steel pipe wall thickness will be uneven, according to the theory, each meter is 8.3844 kilograms, but if the wall thickness is poor 20--30 wire, then the weight will increase some
Q:Is the electric pipe used with steel pipe or PVC pipe?
In industrial designs, galvanized steel tubes are generally used for laying electric tubes, especially in the case of explosion protection.The benefits of galvanized steel pipe is not easy to damage, can prevent the destruction and damage of environmental forces to a certain extent, a junction box, check for export, export lines and other accessories, construction and maintenance in explosion-proof environment can be exempted from hot work. The disadvantage is higher cost.The PVC tube is less costly, but less impact resistant.
Q:What is the difference between hot dip galvanized steel pipe and galvanized steel pipe?
Galvanized steel pipe is commonly known as "cold plated tube", using electroplating process, only galvanized steel pipe in the outer wall, the wall of the pipe is not galvanizedHot dip galvanized steel pipe adopts hot-dip galvanizing process, and the inner and outer walls of the steel pipe have zinc coating.
Q:RC is it welded steel pipe or galvanized steel pipe?
Common pipelines in construction are as follows:SC: welded steel pipeTC: wire tubes, thin steel tubesPC: rigid plastic pipesCT: cable trayCP: metal hoseSR: steel grooveRC: water gas pipe
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.
