Spiral welded pipe: it is made by rolling low-carbon structural steel or low-alloy structural steel strip into pipe blank according to the viewpoint of certain spiral line (called forming angle), and then welding the pipe seam. It can produce large-diameter steel pipe with narrow strip steel. Spiral welded pipe is mainly used for oil and natural gas transportation pipeline, and its standard is expressed by outer diameter * wall thickness. Spiral welded pipe has single-sided welding and double-sided welding. The welded pipe shall ensure that the hydrostatic test, tensile strength and cold bendingof the weld meet the requirements.

7It is divided into circular welded pipe and special-shaped (square, flat etc.) welded pipe.

bWinnipeg C-section steel has uniform zinc layer, smooth surface,Products Show strong adhesion,Belize35CrMo Thick Wall Seamless Steel PipePrésentation de la méthode de production no zinc scar, no zinc leakage and high dimensional accuracy. All surfaces are wrapped by zinc layer, and the zinc content on the surface is usually -g /? It has long service life, corrosion resistance and durability. It is a kind of stronger protection.

Galvanized steel pipe: in order to improve the corrosion resistance of steel pipe, general steel pipe (black pipe) shall be galvanized. Galvanized steel pipes are divided into hot-dip galvanizing and electro galvanizing. The hot-dip galvanizing layer is thick and the cost of electro galvanizing is low.

URobri Multi channel cold rolling (cold rolling) process. Cold rolling of steel pipe is carried out on multi roll mill. Stainless steel pipes are rolled with round holes composed of variable cross-section circular grooves and fixed taper.

Hp The zinc layer obtained by electroplating is relatively pure, alkali and other fog, and can effectively maintain the steel matrix;

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.


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,Products Show and specifications and procedures were formulated.

uWhen selecting I-beam in structural design, chemical properties weldability and structural size.

YThe allowable deviation of vertical installation of galvanized pipe is mm per meter, and the allowable deviation above m is no more than mm. The allowable deviation of horizontally installed pipes is mm per meter.

NtargetHot rolled smooth round steel is structural steel, with chemical composition content of C carbon .%, Si silicon .%, Mn manganese %, s sulfur ≤ .%, P phosphorus ≤ .%, yield strength of mpa and tensile strength of MPa. High temperature continuous casting and rolling or ingot heating rolling. Soft, good weldability,Products Show high ductility,.

iBIn building construction engineering,Belize35CrMo Thick Wall Seamless Steel PipePrésentation de la méthode de production welded steel wire mesh is an essential heat preservation and crack prevention material. It has good performance and can take into account the unity between crack resistance and the requirements of face brick for base strength and the stability of heat preservation system.

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, corrosion resistance and seismic resistance.


Are 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.

OK or not?cCompared with manual binding welded steel mesh can reduce the occurrence of cracks by more than %. The use of reinforcement mesh can make the project construction faster. As long as the reinforcement mesh is laid as required, the concrete can be poured, eliminating the links of reinforcement on-site cutting,Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd placing one by one and binding. It can save % - % of working hours, greatly accelerate the construction progress and shorten the construction cycle.

YDifference and application description between H-beam and I-beam

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.

hWinnipeg The whole structure is composed of zinc and quaternary crystals, forming dense crystals and barrier layer on the plate, which effectively prevents the penetration of corrosion factors. From the point of view of the strong zinc corrosion resistance of the barrier layer, when the zinc sacrificial anode is at the forefront of protection, the scratches and scratches of some coatings and the insolubility of zinc oxide layer play a protective and blocking role.

eMThe reinforcement mesh of the maintenance platform has the characteristics of extensive application, beautiful style, convenient installation and durability, Skirting plate (edge guard plate), installation of connectors and other accessories can be added around. The reinforcement mesh is suitable for the reinforcement mesh manufactured in the factory and welded with cold-rolled ribbed reinforcement or cold-rolled smooth round reinforcement. The welded reinforcement mesh for reinforced concrete is a good and efficient material for concrete distribution. Flat steel with different specifications can be used for edge wrapping, Or wrap edges with angle steel, channel steel, square tube, etc; Handles and hinges can also be installed on the reinforcement mesh that needs to be moved or opened frequently.

Next, let&#;s introduce the operation steps of roll adjustment during roll change. First of all, we must replace the specification and model of the welded pipe manufacturer. Generally, replace the complete set of rolls. The adjustment process of the rolls is as follows: first, draw an axis from the channel of the generator set to the import and export with stainless steel wire for adjustment, so that the holes of each frame plate are on the same axis, and the bottom line of forming ethics meets the technical standards.
