Material requirements

7There 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.

aNorth VancouverAfter the passivation treatment of alloy pipe, it is clearly proposed that water cleaning shall be carried out immediately after the aqueous solution ~ times of water cleaning, and then chromic acid closed solution shall be carried out. Chromic acid solution must be carried out h after the subsequent water cleaning of metallographic structure and austenitic alloy pipe. Chromic acid aqueous solution (mass ratio) is % ~ %, the solution temperature is ~ ℃,Products Show and the solution time is min. Then dry.

First,Cornwall 40CrNiMo alloy pipeFunctional defense dust and other organic matters on the surface of the welded pipe.

WLoyoReinforcement mesh is manufactured by automatic and intelligent production line under the strict quality control of the factory. Grid size, and the load is evenly distributed so it has good bonding and anchorage with the concrete, which obviously shows the seismic crack resistance of the reinforced concrete structure.

HmStretch punching by steel plate equipment; The main purpose is to be used in the structure of scaffold.

After the above process, the next step is the polishing process of stainless steel pipe. There are network standards for internal and external wall finishing of pipelines, and the internal and external surface finishing of pipelines meets the mirror standard (i.e. sanitary standard).

l→ compared with general section steel,Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd it has the advantages of low cost, high precision and small residual stress. It does not need expensive welding materials and weld detection, and saves about % of the manufacturing cost of steel structure.

FIn hardware, you can choose an incomplete performance outside the product. Some construction experts claim that if there is a mechanical effect on these products, they are not suitable. At least this product is impossible.

GManufacturing costThe grid spacing size and number of reinforcement of electric welding reinforcement mesh are correct, which overcomes the phenomenon of large spacing size error and missing binding and buckle of binding quality caused by manual placement of reinforcement in traditional manual binding. The welded steel mesh has high strength and good elasticity. When pouring concrete,Products Show the steel bar is not easy to be partially bent and does not change. Because it is considered that the longitudinal and transverse steel bars are spot welded into a mesh structure, so as to achieve the goal of side-by-side average stress and bonding anchor.

sT 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,Cornwall 40CrNiMo alloy pipeFunctional defense 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.

Galvanized pipe is a layer of galvanized ordinary steel. This is a layer and is a great anti-corrosion protection.

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.

Recommendation and consultationw 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. Galvanized pipe is widely used in architecture. This product must have been seen by everyone. However, there are many types of it. When you buy it,Products Show you should also find out which one you need. The reason why it is favored by everyone in the market is inseparable from its advantages. Next, Xiaobian will lead you to see the advantages of galvanized pipe.

LI-beam is divided into ordinary I-beam and light I-beam. The specification of hot rolled ordinary I-beam is -#. The specification of hot-rolled flexible I-beam supplied through agreement between the supplier and the buyer is -#. I-beam is mainly used in building structure, vehicle manufacturing, other industrial structures and fixed panels and cabinets. I-beam is often used together with I-beam.

China is a big steel country.

iNorth VancouverWhat are the quality protection measures for galvanized pipe during welding

lA Completion of pipeline trench ground; Bricklaying of pipe shaft is completed.

The use of welded steel mesh can make the project construction convenient. As long as the welded reinforcement mesh is laid as required, the concrete can be irrigated, eliminating the links such as on-site cutting, placing and binding of reinforcement one by one.
