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， bridge， which takes hot-rolled steel strip coil as pipe blank， often warm spiral forming and welded by double-sided submerged arc welding. The steel pipe has strong pressure bearing capacity and good welding . After various strict scientific inspections and tests，Products Show and can save the investment in laying pipelines. It is mainly used for transporting oil and natural gas.

Steel mesh guardrail (steel mesh fence) steel mesh guardrail refers to the guardrail made of steel mesh. It is stronger and more durable than the guardrail made of electric welding mesh，Oakville25 galvanized pipe 6 meters, how much is itRecognized by customers steel mesh， hook mesh， etc.， but its cost is much higher， and it is rarely used under normal circumstances
ZPecambaruAre there many welded types of mesh produced? According to the welding type and overall improvement， the difference between the reinforcement mesh and the welded mesh is not particularly large. It is still due to the scattered quality of the southern city. From the perspective of development to the longitudinal and transverse interleaving devices of the reinforcement mesh， the bound or welded mesh has better application quality.
Fz When the end span plate is connected with the concrete beam for structural reinforcement， the length of the surface mesh reinforcement extending into the beam shall not be less than d. When the beam width is small， the extended reinforcement shall be bent . When the perimeter of the floor is poured integrally with the concrete beam or wall，Products Show the length of the surface mesh reinforcement extending into the beam shall not be less than the anchorage length of the small reinforcement required by the standard (without transverse reinforcement)， when the beam width is small， the extended reinforcement shall be bent.
Galvanized pipe: the zinc layer of cold galvanized pipe is an electroplating layer and the zinc layer is separated from the steel pipe substrate. The zinc layer is very thin. The zinc layer is simply attached to the steel pipe substrate and is easy to fall off. Therefore， its corrosion resistance is poor. In new homes， it is forbidden to use cold galvanized pipes as water supply pipes.
Carbon: the higher the carbon content， the higher the hardness of steel， but the worse its plasticity and toughness
f The defects can be removed by grinding with sand wheel， but the remaining wall thickness must be within the allowable standard.
ZSeamless pipe is made of steel block or solid pipe blank， and then made by hot rolling， cold rolling or cold dial. Seamless pipe plays an important role in Chinas steel pipe industry. Seamless pipe production processes are relatively rich，Products Show generally according to the corresponding steps of processing and production.
GPursuit of excellence When the mesh reinforcement on both sides of the beam is different， the reinforcement on both sides extends into the beam，Oakville25 galvanized pipe 6 meters, how much is itRecognized by customers and the reinforcement anchorage length is required.
fW Pickling stainless steel pipe. When removing grease， rust prevention， spot welding， oxide layer， 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.
Polished stainless steel pipes shall be subject to internal inspection and strict manual selection by the steel pipe quality inspector through metal detector (or hydrostatic test)， and qualified products shall be packaged and delivered.
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，Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd 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.
installd Ditch cover plate (ditch cover plate) is widely used in municipal roads， garden facilities residential quarters， schools， stadium pipes and other places.
PApplication characteristics of I-beam
Idler pipe: it is used for electric welding steel pipe of idler of belt conveyor. It is generally made of Q， QA， B steel and steel， with a diameter of -mm. There are certain requirements for pipe tortuosity， end face straightness with the center line and ovality. Generally， water pressure and flattening tests are carried out.
cSudbury 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， and a transverse reinforcement shall be provided at the end of the mesh or the extended reinforcement shall be bent.
vGAccording to the data information display information， there is an inseparable correlation between the annual real estate sales data information and the apparent consumption data information of galvanized pipe. From the consumption surface of the middle and lower reaches of galvanized pipe， decoration design， elevator car， handicrafts， household appliances and other industries are closely related to the situation of the real estate industry.
