- Q:What type of steel pipe dance is used in general?
- According to international competition practice, the standard size of steel tube is 40 mm or 45 mm in diameter, and the 45mm is usually used. The height of the steel pipe is not less than 3.3 meters and not higher than 4 meters.
- Q:How to descaling galvanized steel pipe?
- Is red rust or white rust, red rust is the base material rust, white rust is Zinc Coating Rust
- Q:Is steel pipe made of profiles?
- In accordance with the different smelting quality of steel, steel is divided into ordinary steel and high quality steel. According to the current catalogue of metal products, ordinary steel can be divided into large section steel, medium section steel and small section steel. The section steel can be divided into I-beam, channel steel, angle steel, round steel and so on according to its sectional shape.
- Q:How much is the wall thickness standard of building 48?
- According to the "construction of fastener type steel pipe scaffold safety technical specifications JGJ130-2011" stipulates that the specification of steel pipe should be Phi 48.3 * 3.6, that is, wall thickness is 3.6mm.
- Q:Stainless steel tube, also known as why tube?
- The longitudinal section can be divided into equal section tube and variable cross section tubeThe variable section tube has a conical tube, a stepped tube and a periodically cross section pipe, etc.
- Q:How are steel tubes represented?
- If you speak of steel pipe, if it is water. Gas transmission pipe, then it is said: nominal diameter refers to the inner diameter. The units are millimeters or inches. [for example, water pipes with phi 25. It means that the nominal diameter (diameter) is 25mm (or an inch) steel pipe.
- Q:Is there any difference between HFW steel pipe and ERW steel pipe?
- Resistance welding, as the name suggests, resistance welding is a method of welding by welding electrode after exerting pressure on electrode and utilizing electric current through the contact surface of connector and adjacent zone. High frequency welding: high frequency current through the metal conductor, will produce two kinds of peculiar effects: skin and proximity effects, high frequency welding is the use of these two kinds of effects of steel pipe welding, the effects of the two is based on the high frequency welding metal.
- Q:What's the material of Q325 steel pipe?
- Q235 refers to the material yield stress of 235MPa carbon steel, because of its low price, good machining and welding performance, it is generally used for welding structural parts. Of course, the unimportant parts can be used for it.
- Q:The plastic pipe and steel pipe difference
- Plastic pipe and plastic inner coating, and coated inside and outside. (of course, some are epoxy coated, and some are PE).The plastic tube is one kind of steel pipe, steel plastic pipe has many types, including plastic, plastic, and plastic coated, and epoxy, which are known are steel tubes.
- 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.
