There are many processes in the process of welded pipe processing 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.
4 Pure zinc layer is a plastic zinc layer in hot-dip galvanizing. Its properties are basically close to pure zinc and have ductility so it is flexible.
iBridgetownI-beam has wide flange， thin web， many specifications and flexible use. It can save metal by % ~ % when used in various truss structures. Because the inner and outer sides of the flange are parallel and the edge end is at right angles， it is easy to assemble and combine into various components，Products Show which can save about % of the welding and riveting workload，Barbados18 I-beam price quotationWhat tests should be done before use greatly accelerate the construction speed of the project and shorten the construction period.
Steel transfers heat excellently; Can withstand high temperature; Strong and strong materials; Probably a long time ago. In addition， there is the low cost of metal.
WGusso The cold-rolled stainless steel pipe has the advantages of large yield coefficient， 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， demagnetization， pickling， calibration and other procedures.
Wn The tensile strength of seamless pipe is more than ~ times that of ordinary steel， the elastic coefficient is better than that of steel， and has good creep resistance，Products Show corrosion resistance and seismic resistance.
They do not need to protect them from mechanical damage.
Spiral welded steel pipe (sy- for pile is made of hot-rolled steel strip coil as pipe blank， often warm spiral forming， double-sided submerged arc welding or high-frequency welding. It is used for foundation pile of civil building structure， wharf， bridge， etc.
jAiming at the connective tissue and texture produced in stainless steel plate Position and other crystal defects are generally removed by heat treatment processes such as quenching or quenching. The effect of quenching is to optimize the crystal， eliminate structural defects， reduce strength， improve plastic deformation， and also conducive to cold drawing. In the production and manufacture of cold drawn alloy pipe，Products Show quenching machinery and equipment cannot be lacked. Therefore， reduce the product cost and reduce the quenching process，Barbados18 I-beam price quotationWhat tests should be done before use leveling， crimping and welding， they form round pipes， which are rolled into square pipes， and then cut into the required length. Generally， there are galvanized pipes in each package. In terms of spot， most of them are in large specifications， decorative galvanized pipes，Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd architectural galvanized pipes， mechanical galvanized pipes， etc.
MmanagementWhy are galvanized pipes so good?
iQGalvanized 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.
Filling: welded pipe is welded by electric welding of hot-rolled strip steel， so its influence was not as high as that of seamless steel pipe.
The second is the control of welding materials to ensure that the welding materials purchased are from formal channels， with quality assurance certificate and certificate， which meet the process requirements; The recovery of welding rod head shall be strictly controlled to ensure the flow direction and dosage; Welding materials shall be baked in strict accordance with the process， and the amount of one-time distribution shall not exceed half a day.
how muchiIn order to strengthen the "muscles and bones" of the bridge， the construction party specially paved two layers of reinforcement mesh before pouring cement.
Spray is OK. This method can not only completely remove rust， oxide and dirt， but also the welded pipe will be affected by abrasive impact and friction， resulting in the average roughness of the welded pipe.

iM Seismic and cracking performance the longitudinal and transverse bars of the welded reinforcement mesh form a network structure， so it has good bonding and anchorage with the concrete， and the load can be evenly distributed， which obviously shows the seismic cracking performance of the reinforced concrete structure. According to the actual test， the welded reinforcement mesh laid on the road can reduce the occurrence of cracks than the manual binding mesh. It greatly reduces the unnecessary cost generated manually in the construction and shortens the construction period. The use of reinforcement mesh is simple and convenient， and the reinforcement mesh is convenient for transportation.
Galvanized pipe is often seen in our daily life， especially in some construction sites. This product has the advantage of durability when used. It also has the characteristics of surface gloss， uniform zinc layer and no missing plating. Moreover， the cost of hot-dip galvanizing for rust prevention is lower than that of other paint coatings. In addition， this product also has the characteristics of no dripping， strong adhesion， breaking the clean Legion and strong corrosion resistance. Even if it is used in some places where the environment is not good its service life is also very long， and it also has the characteristics of corrosion resistance. The standard anti rust thickness of hot-dip galvanizing can be maintained for more than years without repair. This is used in some suburban environments. However， in urban or offshore areas， standard urban or offshore areas can be maintained for years without repair. The products produced by our company must meet these requirements.
