What is galvanized pipe
9The 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.
gIndianapolisPatented manufacturing process of I-beam: I-beam has become a new industrial standard for wear-resistant materials
Welded steel mesh is aesthetically pleasing.
YNahongsitamarat Spray is OK. This method can not only completely remove rust， oxide and dirt，Products Show resulting in the average roughness of the welded pipe.
Ie The cold-rolled stainless steel pipe has the advantages of large yield coefficient，Fort Worth12CR2MOG alloy pipeStrategies and solutions to maximize value no expansion， bending and so on. In order to reach the health grade standard of stainless steel pipeline， the pipeline after cold rolling must undergo bright annealing， pickling， calibration and other procedures.
There shall be no bending at the welded junction， and there shall be no staggered joint during assembly. Electric welding positioning is generally spot welding. After inspection and straightening， the free conversion method shall be used for welding as far as possible.
pI-beam is mainly divided into ordinary I-beam， light I-beam and wide flange I-beam. According to the height ratio of flange to web， it is divided into wide，Products Show medium and narrow flange I-beams. The specifications of the first two are -， that is， the corresponding height is -. At the same height， the light I-beam has narrow flange， thin web and light weight. Wide flange I-beam， also known as H-beam is characterized by two parallel legs and no inclination on the inner side of the legs. It belongs to economic section steel and is rolled on four high universal mill， so it is also called "universal I-beam". Ordinary I-beam and light I-beam have formed national standards.
LGenerally speaking， the precision of seamless pipe is relatively low， and it is prone to uneven wall thickness， low surface luminosity and high customization cost. At the same time，Products Show some pits or black spots are easy to appear on the inner and outer surfaces. In addition to these， the seamless pipe manufacturer needs to carry out off-line processing for its detection and its strength is relatively high，Fort Worth12CR2MOG alloy pipeStrategies and solutions to maximize value the pressure is high and its advantages can be reflected in the material of mechanical structure. Seamless pipe can be divided into hot extrusion， hot rolling and cold rolling stainless steel pipe according to its rolling method. In addition， different elements can also be used for classification. The inner and outer surfaces of seamless pipes shall be free from chaps， folds， cracks， scabs， delaminations and other defects. If these defects are to be removed， it is necessary to use machining. The removed seamless pipes shall not have negative deviation after the inner diameter is followed，Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd If other minor surface defects with negative deviation cannot be removed， it is not a qualified product. The allowable depth diameter of straight path of seamless pipe is less than or equal to mm， and its depth shall not be greater than . mm.
AHigh quality brand Pipe installation:
nFWhat are the advantages of seamless pipe?
Cleaning: first， clean the grease， dust and other substances attached to the surface of the galvanized pipe after cleaning.
They are not affected by surrounding factors and processes including corrosion.
Safety productionwThe third is the welding machine， which must ensure reliable performance and meet the process needs; The welding machine must have qualified ammeter and voltmeter to ensure the correct implementation of welding process. The welding cable shall not be too long， and the welding parameters shall be adjusted when it is too long.
DThe flange of H-beam is of equal thickness， including rolling section and combined section composed of three plates welded. All I-beams are rolled sections. Due to poor production technology， the inner edge of the flange has a slope of : The rolling of H-beam is different from that of ordinary I-beam. Only one set of horizontal rolls is used. Because its flange is wide and has no inclination (or the inclination is very small)， a group of vertical rolls must be added for rolling at the same time. Therefore， its rolling process and equipment are more complex than ordinary rolling mills. The maximum height of rolled H-section steel that can be produced in China is mm， and every detail needs our attention. Welded pipes need to be treated by various processes before application. Heat treatment of welded steel pipe is an important link in the process of welding steel pipe. Hot working is a metal hot working process in which metal materials are heated， insulated and cooled in a certain medium， and the metal properties are controlled by changing the metallographic structure on the surface or inside of the material.
mIndianapolis After chromate passivation， the zinc coating forms white， colorful and military green， which is beautiful and generous and has certain decoration;
gH According to the diameter of the pipe， the pipe with small diameter can only be welded on one side and the technician can drill into the pipe to weld on both sides. Single side welding requires the welders technology， which can be formed by welding two on one side. Through the steel ball test， it can ensure that the cross-sectional area passing capacity and weld formation meet the design requirements.
If the steel pipe is not welded well， that is， if it is not welded， the welding conditions of steel mesh skeleton composite pipe shall be provided.
