 The anti-corrosion operation we first discuss refers to the routine maintenance of spiral steel pipes that have not been treated with anti-corrosion treatment. Because of its good anti-corrosion performance, the anti-corrosion spiral steel pipe is relatively less affected by the season, but for conventional spiral steel pipes (SSAW) , summer is a season that is easy to be corroded. In summer, the humidity in the atmosphere increases, coupled with the increase in rainy weather, many coiled pipes are stored outdoors, resulting in frequent exposure to wind, rain and scorching sun. If the spiral steel pipe needs to be stored for a long time, a part of the oily substance can be sprayed on the surface to isolate the oxide layer. Try to avoid placing the spiral tube in a low-lying place, which will cause excessive moisture and aggravate oxidation. Other anti-corrosion methods using steel pipes are often referred to as anti-corrosion spiral steel pipes. This processing method refers to co...

 Tianjin Xinyue Steel Pipe is sold all over the world, making a strong contribution to the world's infrastructure, bridges, offshore construction and oil pipeline transportation. And steel pipe export can not be separated from shipping, can not be separated from FOB trade, now give you a general idea of what FOB terms. 1.FOB Liner Terms This distortion means that the cost of shipment is handled in accordance with the liner's practice, i.e. it is borne by the ship or the buyer. Therefore, with this deformation, the seller will not bear the costs associated with shipment. 2. FOB Under Tackle The seller shall bear the cost of delivering the goods to the place where the hook of the vessel designated by the buyer can reach, and the buyer shall bear the cost of hoisting into the hold and other expenses. 3. FOB Stowed It means that the seller is responsible for loading the goods into the hold and for the cost of loading, including the handling fee. Cargo handling fee refers to the cos...

 The surface quenching and tempering heat treatment of seamless steel pipes is usually carried out by induction heating or flame heating. The main technical parameters are surface hardness, local hardness and effective hardened layer depth. Vickers hardness tester can be used for hardness testing, Rockwell hardness tester or surface Rockwell hardness tester can also be used. The selection of the test force (scale) is related to the depth of the effective hardened layer and the surface hardness of the seamless steel pipe. There are three durometers involved here. 1. Vickers hardness tester is an important means to test the surface hardness of heat-treated seamless steel pipes. It can use a test force of 0.5-100kg to test the surface hardened layer as thin as 0.05mm thick. It has the highest accuracy and can distinguish the heat treatment. Small differences in surface hardness of seamless steel pipes. In addition, the depth of the effective hardened layer is also detected by a Vicker...

 The reasons for the deformation of carbon seamless steel pipes are often complicated, but as long as we master the laws of deformation, analyze the causes, and use different methods to prevent the deformation of the mold, it can be reduced and controlled. In general, the heat treatment deformation of seamless steel pipes can be prevented by the following methods. (1) Reasonable selection of materials. For seamless steel pipes, micro-deformation die steels (such as air-quenched steels) with good quality should be selected, and die steels with serious carbide segregation should be reasonably forged and quenched and tempered. Refinement heat treatment. (2) The design of the mold structure should be reasonable, the thickness of the seamless steel pipe should not be too large, and the shape should be symmetrical. For the mold with large deformation, the deformation law should be mastered, and the machining allowance should be reserved. For large and seamless steel pipes, a combined str...

 Seamless steel pipe (smls pipe) is a non-combustible building material, which has the characteristics of earthquake resistance and bending resistance. In practical applications, seamless steel pipes can not only relatively increase the load capacity of buildings, but also meet the needs of architectural design aesthetic modeling, and also avoid the defects that concrete and other building materials cannot be bent and stretched. The industry’s favor, single-storey, multi-storey, skyscrapers, factories, warehouses, waiting rooms, waiting rooms, etc. use seamless steel pipes. However, as a building material, seamless steel pipe has some unavoidable defects in fire prevention. Its mechanical properties, such as yield point, tensile strength and elastic modulus, will drop sharply due to the increase of temperature. The seamless steel pipe usually loses its bearing capacity at a temperature of 450-650 °C, and a large deformation occurs, resulting in the bending of the steel column and t...

 In recent years, with the continuous upgrading of the welding process of large-diameter spiral steel pipes (SSAW), the processing quality and process performance will be significantly improved. Therefore, the quality of the factory will also have differences in grades. Among them, after the types of such pipes sold in the market continue to increase, there will be a very large gap in their quality. So, what exactly determines it? Factor one: material grade. Under normal circumstances, the materials used for the processing of large-diameter spiral steel pipes are divided into many grades. Each grade is different, and there are usually very large differences in quality. Therefore, to determine whether the quality is good or not, the manufacturer must present the corresponding material certificate, so that the level of the grade will be known. When compared in this way, it can be seen that the quality is not the same. Factor two: workmanship quality. Of course, when large-diameter sp...
