6The smooth of steel pipe is mainly through tension reducing， which is a continuous rolling process of hollow base metal without center and tip. Under the condition of ensuring the capillary welding quality， the whole welded pipe is heated to more than ℃ by the welded pipe tension reduction process， and then rolled to finished pipes with various outer diameters and wall thicknesses by the tension reduction machine ( times in total). The fluid pipes produced by developed countries in the world have adopted the welded pipe smooth process in a large number of boiler pipes. With the development of society， Domestic hot welded pipe has gradually formed a situation to replace smooth pipe.
gScottsdale The defects can be removed by grinding with sand wheel， but the remaining wall thickness must be within the allowable standard.
Emulsified asphalt emulsion is also easy to use on the mobile slurry seal paver. It is necessary to mix on the machine and use additives for chemical control for maintenance.
NTrevnerThe electric welding reinforcement mesh can reduce the damage and consumption to the reinforcement processing process. According to statistics，Products Show after deducting the steel consumption increased by unit lapping，Garland16Mn seamless pipe manufacturerIn which areas shine it can also save about % of the steel. After it is transported to the site according to the construction degree of the project， it can be hoisted to the working face. There is no need to set a reinforcement processing site on the site， which saves the site and increases the management level of the site. At the same time， it can also solve the problems of noise pollution caused by straightening reinforcement.
PsGalvanized pipe: the hot-dip galvanized pipe base plate and molten electroplating solution are combined physically and chemically to form a dense corrosion-resistant structure of zinc iron alloy layer. The alloy layer is integrated with the pure zinc layer and the steel pipe substrate. Therefore， it has strong corrosion resistance.
Ditch cover plate (ditch cover plate) is widely used in municipal roads garden facilities， residential quarters， schools， stadium pipes and other places.
As long as the pipe material is high-strength alloy steel， including alloy steel pipes with temperature resistance，Products Show pressure resistance， wear resistance and low temperature resistance， the welding process shall be focused on preventing the tendency of martensite structure and cracks due to welding high-temperature operation. The general process requirements are that the welding rod shall be selected and baked as required and sent to the welder for use. The oil and water shall be removed before welding on both sides of the weld Rust and sundries shall be removed and cleaned. The welding line energy shall be as small as possible to minimize the swing during the welding process. The arrangement of the last weld shall have annealing effect on the heat affected zone as far as possible. Slow cooling after welding， cover with asbestos cloth， etc.
r Cold extrusion. This kind of processing method is more purposeful. Before the preparation of steel processing and extrusion molding， when the extrusion molding is used for mm diameter pipe fittings the investment of machinery and equipment is less， so the raw material consumption is also very small， and the technology is relatively perfect. Once the tube size is increased， the cold extrusion method must have large cargo capacity and high-power machinery and equipment. Therefore， the automatic control system will be upgraded.

KSales Department Spiral seam high-frequency welded steel pipe (sy- for general low-pressure fluid transportation takes hot-rolled steel strip coil as pipe blank and is often spiral formed at warm temperature. High frequency lap welding method is selected for welding spiral seam high-frequency welded steel pipe for general low-pressure fluid transportation.
rR Platform reinforcement mesh is a widely used reinforcement mesh product，Products Show berm， municipal administration electric power，Garland16Mn seamless pipe manufacturerIn which areas shine coal mine and other fields， and has the strongest resistance to surface impact， especially the reinforcement mesh with a cross bar spacing of mm has a strong ability to resist lateral impact.

The seamless pipe produced by the seamless pipe manufacturer is a long seamless pipe without any joints around and with hollow section. The thicker the wall of this product produced by the manufacturer， the higher the use value and economic value of this product. If its wall thickness is thinner， its processing composition will increase significantly， Secondly， the product technology produced by this seamless pipe manufacturer often determines its limitations.
superior qualityo The end span plate is connected with the load-bearing wall. The length of the surface mesh extending into the grid support shall not be less than mm， it is the process of penetrating nitrogen atoms into the surface layer of steel. At present， gas nitriding is widely used in the production of alloy steel pipe.
According to the pipe wall thickness， pipes made of relatively thin materials such as steel strip can be welded with high frequency， and some thin-walled pipes can be welded with shielding gas; Pipes with wall thickness more than mm can be welded by hand.
jScottsdale It has iron zinc alloy layer and compact combination， which shows unique corrosion resistance in marine salt spray atmosphere and industrial atmosphere;
xP It has a thick and dense pure zinc layer covered on the steel surface， which can prevent the steel substrate from touching with any corrosion solution and maintain the steel substrate from corrosion. In general atmosphere， the surface of zinc layer forms a thin and dense zinc oxide layer， which is difficult to dissolve in water， so it plays a certain maintenance effect on steel matrix. If zinc oxide and other components in the atmosphere form insoluble zinc salts， the anti-corrosion effect is more ideal.
Galvanized pipes shall be stored in dustproofto keep clean and new . As a professional manufacturer of galvanized pipe， we have produced galvanized pipe products for many years. Welcome friends who need to buy.
