Product Description:

1Structure of Seamless Pipe ASTM A106/53: 

Seamless pipe is formed by drawing a solid billet over a piercing rod to create the hollow shell. As the manufacturing process does not include any welding, seamless pipes are perceived to be stronger and more reliable. Historically seamless pipe was regarded as withstanding pressure better than other types, and was often more easily available than welded pipe. 

Application

carbon seamless steel pipes are widely used in gas, water and oil, transpotation;constructions;Bridge,highway,windows of model steel door; building materials;fences;heating facilities Fluid Pipe;conduit pipe,scaffolding pipe.etc.

Q:What's the difference between stainless steel decorative pipes and polished stainless steel pipes?
Polished stainless steel pipe is different from stainless steel decorative tube, generally speaking, the material is better. Yes, the steel tube just appeared is a bit rough and not smooth enough, so it needs polishing to make it appear smooth. Mostly Austrian stainless steel, nickel, corrosion resistance, but the price is expensive, mainly for industrial and outdoor decoration.
Q:Can stainless steel pipes spray black paint
Stainless steel pipes can spray black paint.The surface of stainless steel has a smooth surface
Q:What kind of stainless steel square tube is used in ordinary square tubes?
General specifications of stainless steel tube at the inner diameter and wall thickness, the length can be decided according to the needs of consumers, the common market of stainless steel pipe specifications are: diameter more than 6.0mm, the wall thickness below 13mm; diameter greater than 30mm, the wall thickness is greater than 1.2mm; diameter greater than 30mm, wall thickness less than 1.2mm.
Q:How can the inner walls of stainless steel tubes be polished?
Electropolishing is thrown to the workpiece as anode, insoluble metal poles at the same time as the cathode, immersed into electrolytic cell, with the direct current produced anodic dissolution selectively, so as to achieve the surface brightness increasing effect. Specific can be used to search "what is electrolytic polishing" can understand!
Q:What does "stainless steel pipe" DN mean?
In order to connect the pipe and pipe fittings in a unified way, nominal diameter (also called nominal diameter, nominal diameter) is adopted. For example, welded steel pipes can be divided into thin wall steel pipes, ordinary steel pipes and thickened steel pipes according to their thickness. Its nominal diameter is neither external diameter nor internal diameter, but a nominal size similar to the diameter of the ordinary steel pipe. Each nominal diameter corresponds to an outer diameter, and the inner diameter varies with the thickness. Nominal diameter can be expressed in metric mm, also available in English in. With nominal diameter pipeline accessories, meaning with tube.
Q:Is galvanized steel pipe stainless steel pipe?
Not galvanized pipe, but the surface of the welded pipe galvanized zinc rust protection. The stainless steel pipe is welded by stainless steel band, or made of stainless steel bar punched (seamless pipe). And the two prices are very different
Q:What is the difference between the stainless steel tube and tube rolling
We usually say the hot-rolled seamless slide into thermal expansion, is to use tools of the pipe up, supporting circle. Cold is the opposite, a fixed mould outside the inner hole of the fixed mandrel, from the outside to make him thinner. Annealing is required before hot rolling, without cold rolling. In hot rolling billet after annealing, stainless steel seamless pipe, wall production minus a broaching machine after reaming compression capability, good flexibility, technological properties were superior to those of ordinary tube ligation.Now the Zhejiang area in the production of stainless steel seamless pipe is widely used cold production technology, but higher production efficiency of 2 roller cold rolling mill, a lot of strength of the manufacturers are equipped with, because the price of the purchase quantity not more general factory. It is commonly used in conjunction with cold drawn units to increase efficiency and reduce production costs.It is precisely because of their differences in production and processing technology, but also makes the hot-rolled stainless steel and cold-rolled pipe has the following differences:A: seamless pipe and tube rolling produced products, though they are working with the tube, but the application is different, generally used for mechanical drawing, heat exchanger pipe, pipe and tube rolling engineering, generally used for fluid transport in pipeline construction;Two: seamless pipe and tube rolling process and product quality; slide processing, low defect, high precision, uniform grain size;Three: two different prices, the price to slide rolling ratio is more expensive;Four: the stainless steel tube ligation can only in diameter 38-159 pipe, or other drawing process. Because of the production process, the tube size is relatively accurate. In the purchase of steel tubes, or tube rolling is drawing, but also the actual situation needs to choose.
Q:What wire is used for welding of 316 stainless steel line?
Inspection of assembly and tack welds;1, check the geometry and shape after assembly, whether it conforms to the provisions of the drawings. :2, assembly and assembly clearance is 1.5 - 2mm, using TIG welding, three point positioning welding,The welding seam position for the clock 3 points, 9 points and 12 points, the welding materials used should be the same as the welding materials, welding length is 10 15mm, welding requirements and guarantee no defect, the wrong side is less than 1.5 2mm.3, the group is not allowed to use strong assembly, the joint wall must be flush.4, when welding, there must be no air, slag, tungsten and crack.
Q:How thick is the 3 stainless steel tube?
All units of steel default are mm mm. stainless steel 3 thick meaning, that is, the thickness of 3 mm mean
Q:What is 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.
