Seamless tube has high elasticity， can be reused on mechanical equipment， no memory， no deformation， anti-static.
7They do not need to protect them from mechanical damage.
pFloridaI-beam， also known as steel beam is a long strip of steel with I-shaped section. I-beam is divided into ordinary I-beam and light I-beam. It is a section steel with I-type section shape.
Why are galvanized pipes so good?
CGhanaGalvanized pipes are designed to maintain high enough corrosion resistance.
YkHow to judge the quality of seamless pipe?
The development of steel bar mesh is in line with the development of energy-saving economy
With the development of China&#;s infrastructure，Produits Afficher and the demand for welded steel mesh for capital construction such as power，colonCold drawn welded pipe manufacturerHow to speed up marketization and eliminate backward production capacity transportation， water conservancy， housing and municipal engineering will increase exponentially.

X After hot-dip galvanizing of steel structure， it is equivalent to one-time annealing treatment， which can effectively improve the mechanicalof steel matrix，Barres d'armature, tubes galvanisés, tubes sans soudure, tubes soudés, tubes en alliage, I - Steel - Shandong Kevin Metal Materials Co., Ltd. eliminate the stress during steel forming and welding， and is conducive to turning of steel structure.
CMarket trend For the surface mesh of the height difference plate， when the height difference is ≤ mm， the surface mesh can be bent and installed; when the height difference plate is more than mm， the surface mesh should be disconnected at the place with height difference and put into the beam respectively. The anchorage length of the reinforcement is required for the reinforcement to extend into the beam.
aT It is the trend of the development of steel bar industry to take the road of steel bar welding mesh in steel bar construction.
Material requirements
Transformer tube: it is used to make transformer heat dissipation tube and other heat exchangers. It is made of general carbon steel. Flattening， flaring，Produits Afficher zigzag and hydraulic tests are required. Steel pipes are delivered in fixed length or double length， and there are certain requirements for the tortuosity of steel pipes.
Where can I find it?xIt bears high internal working pressure.
KPatented manufacturing process of I-beam: I-beam has become a new industrial standard for wear-resistant materials
Pickling stainless steel pipe. When removing grease， rust prevention spot welding， oxide layer，colonCold drawn welded pipe manufacturerHow to speed up marketization and eliminate backward production capacity free iron and other dirt， the surface shall be treated with silver to evenly slow down the pickling surface， prevent metal corrosion and hydrogen embrittlement and inhibit fog production.
kFlorida As long as the pipe material is high-strength alloy steel， including alloy steel pipes with temperature resistance，Produits Afficher 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， reinforcement specification and quality are strictly controlled. The longitudinal and transverse bars of the reinforcement mesh form a network structure， so it has good bonding and anchorage with the concrete， and the load is evenly distributed， which obviously shows the seismic crack resistance of the reinforced concrete structure.
