- Q:What's the difference between stainless steel seamless tube and stainless steel welded pipe?
- Stainless steel seamless pipe featuresFirst, the product of the wall is thicker, it is more economical and practical, the wall thickness of the thinner, processing costs will be substantially increased it; secondly, the product process to determine its performance limitations, generally low precision seamless steel pipe: uneven thickness, tube inner surface brightness low and high cost of fixed length, and the inner surface pitting and black spots difficult to remove; the detection and plastic third, must be processed offline. Therefore, it has its advantages in high pressure, high strength, mechanical structure and timber.
- Q:What is hot rolled steel pipe? What is a cold drawn steel tube?
- General use seamless steel tube: is with 10, 20, 30, 35, 45# and other high-quality carbon steel, 16Mn, 5MnV and other low-alloy structural steel or 40Cr, 30CrMnSi, 45Mn2, 40MnB and other alloy steel hot-rolled or cold rolled. Seamless tubes made of low carbon steel, such as 10, 20, are mainly used for fluid delivery pipelines. 45. Seamless tubes made of medium carbon steel such as 40Cr, used for the manufacture of mechanical parts, such as parts of automobiles and tractors. General use of seamless steel pipe to ensure the strength and flattening test. Hot rolled steel tubes are delivered in hot rolling or heat treated conditions. Cold rolled in heat treated state.
- Q:Seamless steel tube with the tube with what is the difference?
- Of course, the market also has some use overall heating after drawing steel pipe joints or mandrel rolling seamless steel pipe, mainly in small size, only in the shape of this kind of pipe belongs to the seamless tube, it is not very good, pay attention to oh!!
- Q:Is the PVC tube a plastic tube or a plastic tube?.
- PVC is actually a vinyl polymerization substance, whose material is a non crystalline material. Polyvinyl chloride (Poly, Vinyl, Chloride, PVC), it is obviously impossible to steel, we often say that iron and steel, the steel must be the main component of iron, Fe, inorganic. And PVC, polyvinyl chloride, is an organic substance. Therefore, PVC can not be called steel, and PVC constitutes a large number of substances, not confined to the pipe type.
- Q:Stainless steel tube, also known as why tube?
- It can be divided into round tube and special-shaped tube according to the cross sectional shapeThe special-shaped tube has a rectangular tube, a rhombus tube, an elliptical tube, six square tubes, eight square tubes, various cross section asymmetric pipes, etc.
- Q:What does "spiral welded steel pipe" DN325*10 mean?
- Spiral welded steel pipe with nominal diameter of 325mm and wall thickness of 10mm
- Q:What's the actual size of the DN25?
- DN25 refers to the theoretical size of the inner hole of the pipe. That is to say, the theoretical dimension of the inner diameter of the pipe is 25 (the metric tube refers to the inner diameter, and the English tube is also to indicate the inner diameter, for example: 3/8, the inner diameter is 9.525, and the diameter of the 1/2 is 12.7, and the diameter of the 5/8 is 15.875). The outer diameter is theoretical in diameter, plus the wall thickness specified by the state (which is artificially specified and has no formula)The theoretical diameter of DN25 is 25, and the outer diameter is Phi 33.7 and phi 32(but there is also the outside diameter of the mark. The mark is: the outer diameter * wall thickness, such as: 32 * 2, that is to say, the outer diameter is 30, the inner diameter is 26)
- Q:What type of steel pipe for security windows?
- 25 parties, 70 parties in general! Good point of about 90; 25/38 general 90, a good point of about 120! The model is usually 202. If 304 is used, it is usually multiplied by 2! Plastic steel window material is hard plastic! Inside a single glass lined steel prices have 75/90/120/150/ different brand price this is the price of the window! Aluminum alloy is generally 100/120/150/175/190 area, different prices different
- Q:Is steel pipe made of profiles?
- Large steel: large steel, I-beam, channel steel, angle steel and flat steel are hot rolled, round bar, Fang Gang, six angle iron in addition to hot rolling, there are forging, cold drawn and so on.
- Q:What place must use galvanized steel pipe to make lighting line?
- Galvanized pipe for pipeline laying construction and transformation of lighting, power, telephone, fire protection system in the engineering (made of galvanized steel), for laying, laying can be laid in the dark, the wall can also be installed on the ceiling.
