- Q:What does "spiral welded steel pipe" DN325*10 mean?
- Labeling is wrong: it should be said for 325*10, the diameter of pipe wall thickness of 10, 325;For example, the nominal diameter shall be: DN300.
- Q:How to establish a concrete-filled steel tubular column model in ANSYS?
- A two unit model or a composite unit model can be adoptedTwo units are constructed of steel tubes and concreteA composite unit may be either a fiber element or a section conversion attribute
- Q:There are multiple welded galvanized steel pipe outer diameter 108mm wall thickness 4mm length of 6 meters
- Galvanized steel pipe wall thickness weight outer diameter 108mm 4mm 6 meters in length is about 10.26*6*1.06=65 kg.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%.
- Q:What kind of argon arc welding wire is used for 16Mn steel pipe?
- 16Mn steel weldability is very good, general use TIG with J50 welding wire, hand arc welding with J506, J507 and other welding rod
- Q:How do you solder purple copper plate and steel tube?
- When the copper and copper tube size is too large, argon welder welding, DC argon arc welding machine, of course, when DC argon arc welding welding belongs to welding, argon arc welding of brass with Wei Odin 204S welding, the argon arc welding wire for gas welding is not brass wire, this concept must be clear, the wire diameter of 2 80-120A, welding current parameters, if the copper thickness is relatively thick, with a red copper welding after welding preheating in advance.
- 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:Are galvanized steel tubes the same as degaussing steel tubes?
- Degaussing steel tubeThe degaussing method specifies the following demagnetization in the established process document
- Q:Fastener type steel pipe scaffold steel pipe wall thickness
- The scaffold steel pipe shall be made of 48.3 * 3.6 steel tube. The maximum mass of each steel tube shall not be greater than 25.8kg.Fastener type steel pipe scaffold: for building construction and build, bear the load by the fastener and steel pipe and other scaffolding and support frame, collectively referred to as scaffolding. The fastener is a fastening piece which is fastened by bolts.
- Q:Is the seamless steel pipe used in the market hot or cold drawn?
- Small and medium-sized cold drawn and hot-rolled are many, large caliber is hot rolling, cold rolled spot less.
- Q:Are there specifications for scaffold steel pipe with 48mm * 3.2mm?
- 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.
After more than a decade’s construction and development, we have taken a leading position in seamless steel tube industry in China. In the year 2007, it awarded Famous-brand product Certificate. Besides, we have been named as excellent supplier of Qualified Products by our customers for several times.
