The pipeline shall be positioned according to the drawing design， and the pipeline support shall be prefabricated according to the site conditions. Hang the wire from the th floor down and fix the support.

iCatagoWhat is the purpose of flat steel
The use of welded steel mesh in China is still in its infancy. At present the use of welded steel mesh in China accounts for less than one of the total amount of steel reinforcement. In the early s， steel welded mesh was listed as a key implementation project by the science and Technology Commission and the Ministry of construction， and specifications and procedures were formulated.

IfBecause of this characteristic， natural gas， natural gas，Products Show water and some solid materials transportation. Smooth steel pipe has strong bending advantages compared with other steel pipes. And the smooth steel pipe is also light in weight. It is a very economical single-sided steel.
If the steel pipe is not welded well，Ibis80 welded pipe more than one meterVisualization technology that is， the welding conditions of steel mesh skeleton composite pipe shall be provided.
According to the process， it is divided into arc welded pipe， resistance welded pipe (high frequency and low frequency)， gas welded pipe and furnace welded pipe.
vI-beam features: the content of chromium carbon alloy is -%， the hardness of chromium carbide alloy is V， and the macro hardness is - HRC
H The weight of seamless pipe is light， and its weight is only one fifth of that of anti steel.
RPotential developmentThe production of plastic impregnated welded steel wire mesh is to immerse the formed welded steel wire mesh into a stone groove filled with PVC powder. The dry forming process is complex and the cost is much higher than that of spray welded mesh. Due to different application ranges and different uses， the choice is expensive or cheap，Products Show and then the groove shall be made with a grinder with a groove angle of ° ~ °. Fix the processed pipe on the support and the gap between the two pipes is mm ~ mm， and then weld.
The fifth is the welding environment control to ensure that the temperature， humidity and wind speed during welding meet the process requirements.
What are the advantages of seamless pipe?
Application processk If the surface of the welded pipe is rusty， we can polish the appearance of the welded pipe with a wire brush to prevent rust.
QI-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， 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，Products Show thin web and light weight. Wide flange I-beam， also known as H-beam，Ibis80 welded pipe more than one meterVisualization technology 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.
How are seamless tubes made?
jCatagoThey do not need to protect them from mechanical damage.

Spiral seam high-frequency welded steel pipe (sy- for pressure fluid transportation is a spiral seam high-frequency welded steel pipe used for pressure fluid transportation， which takes hot-rolled steel strip as pipe blank， often warm spiral forming and high-frequency lap welding method. The steel pipe has strong pressure bearing capacity and good plasticity， which is convenient for welding and processing; After various strict and scientific inspections and tests， the application is safe and reliable， the diameter of steel pipe is large， the transportation efficiency is high， and the investment in laying pipeline can be saved. It is mainly used for laying pipelines for transporting oil，Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd natural gas， etc.
