Q:How can galvanized steel pipe be connected with stainless steel pipe?
Welding methods are used to connect. Because galvanized pipe is in fact carbon steel pipe, so galvanized pipe and stainless steel pipe welding, in fact, carbon steel and stainless steel welding, welding of dissimilar materials.
Q:What's the material of Q325 steel pipe?
Plain carbon structural steelIt's a kind of steel material. Q stands for the yield of this material, and the latter 325 means the yield value of this material, at around 325. And the yield value will decrease as the thickness of the material increases.
Q:The outer circle of a seamless steel pipe 50 head into the outer circle of the 40 to close
That is, according to the production process of different classification, different from hot rolling (expansion) pipe. In the process of expanding the tube or raw material tube, it is processed by multiple cold drawing, usually on single chain or double chain cold drawn machine of 0.5 ~ 100T. Cold rolled steel pipe (DIAL) in general, steel pipe for low and medium pressure boiler tube, high-pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, oil cracking tube, machining pipe, thick wall pipe, small diameter and cold drawn steel tube also includes other tubes, carbon thin-walled steel, alloy thin-walled steel pipe, stainless steel pipe, special-shaped wall steel pipe. The outside diameter of cold drawn steel tube wall thickness to 6mm, to 0.25mm, to 5mm diameter thin-walled tube wall thickness is less than 0.25mm in size, accuracy and surface quality were significantly better than the hot (expanding) tube, but by the process control, its diameter and length are limited.
Q:What is the buckling type thin-wall steel pipe? What is a tight set of thin-walled steel tubes? What's the difference between the two?
The nut body and the junction box are connected at one end by adopting metric fine tooth thread, and the pipe is connected with the pipe, and one end is the same as the straight pipe joint (direct). Withhold the box joint points inside and outside teeth two. The diameter of straight pipe joint is divided into 16mm, 20mm, 25mm, 32mm, 40mm, 50mm.
Q:Who knows what is the difference between double submerged arc welded pipe and longitudinal submerged arc welding?
Double submerged arc welding should be for spot welding and single side welding, they are straight line welds, but double submerged arc welding seam is more beautiful and fine.
Q:Is there any difference between HFW steel pipe and ERW steel pipe?
The difference between ERW (longitudinal resistance welding) and HFW (high frequency welding) is mainly due to the different principle.
Q:Does the seamless steel pipe need rust removal?
Spray (throw) shoot derusting by the high-power motor to drive the spray shot (impeller) blade rotating speed, the steel grit, steel shot, iron wire, minerals and other abrasive jet for 20# seamless steel tube surface under the action of centrifugal force (left) radiation treatment, not only can completely remove the dirt and rust, oxide, and the role of 20# seamless steel in abrasive blast and friction force, can achieve the required uniform roughness.Not only can the physical adsorption effect on the surface of the pipe be increased, but also the mechanical adhesion of the anticorrosive layer to the pipe surface can be enhanced. Therefore, spraying (throwing) shot derusting is an ideal method of rust prevention for pipeline corrosion protection. Generally speaking, shot peening (sand) derusting is mainly used in the inner surface treatment of tubes, shot blasting (sand) derusting is mainly used for the outer surface treatment of tubes.
Q:How much is the tube?
The first prerequisite we need to determine is: what are the specifications of the steel pipe mentioned? Such as the commonly used steel pipe specifications: diameter 108*4.5, diameter 219*6, diameter 377*10, diameter and wall thickness of steel pipe with different specifications, different weight, so the steel price per meter is different.
Q:What materials are used in scaffolding pipes?
Using 48.3 * 3.6mm steel pipe, the maximum thickness of the steel pipe shall not be less than 3.24mm (there should be no serious corrosion, bending, flattening or crack); the corrosion depth of the old steel pipe shall be in accordance with the construction fastener typeProvisions on the safety technical specification for steel pipe scaffold JGJ130-2011. Take three of the corroded steel tubes, and cut the samples at the most severe parts of the rust. The corrosion depth shall not exceed the prescribed valueUse。 In addition, the approach of the steel pipe should also be sampling retest, qualified before use.
Q:What kinds of steel pipe are divided into?
Welded pipe: also known as welded pipe, is made of steel or steel strip after bending forming, and then made by welding. In accordance with the form of weld is divided into longitudinal welded pipe and spiral welded pipeSpecifically refers to the use of welded steel strip or plate bending deformation of round, square shape after welded, surface jointed steel pipe. The welding steel billets is used in steel plate or strip. The welded pipe production process simple, high production efficiency, great variety, less capital equipment, but since the general strength is less than that of seamless steel.20 century 30s, along with the rapid development of high-quality strip rolling production and progress of welding and testing technology, and constantly improve the weld quality, varieties and specifications of welded steel pipe is increasing, and instead of the seamless steel pipe in more and more fields. Compared with welded steel seamless steel tube with low cost and high production efficiency.
Perfect detection system, our physical & chemical laboratory is equipped with test facilities included spectrum detection and metallographic analysis etc. The company has successively passed ISO9000 quality system, the American Petroleum Institute API, and also earned the environment healthy license, national special equipment manufacturing license.
