According to the section shape, the steel pipe is divided into:

9Galvanized 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.

oChatham KentNitriding: also known as nitriding, it is the process of penetrating nitrogen atoms into the surface layer of steel. At present, gas nitriding is widely used in the production of alloy steel pipe.

It has a thick and dense pure zinc layer covered on the steel surface, which can prevent the steel substrate from touching with any corrosion solution and maintain the steel substrate from corrosion. In general atmosphere,Products Show the surface of zinc layer forms a thin and dense zinc oxide layer,ريجيناDN32 المجلفن الأنابيبنطاق قابل للتطبيق which is difficult to dissolve in water, so it plays a certain maintenance effect on steel matrix. If zinc oxide and other components in the atmosphere form insoluble zinc salts, the anti-corrosion effect is more ideal.

XPabiannis 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.

Xn . the straight length of the hook of the surface mesh reinforcement at the grid support shall not be less than mm, and the bending diameter shall not be less than D (D is the reinforcement diameter).

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.

wPass design

FThe 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.

Ptechnical service The zinc layer obtained by electroplating is relatively pure, which corrodes slowly in acid alkali and other fog, and can effectively maintain the steel matrix;

pK It has iron zinc alloy layer and compact combination, which shows unique corrosion resistance in marine salt spray atmosphere and industrial atmosphere;

In order to ensure the welding quality of welded pipe, the forming roll,Products Show guide roll, extrusion forming roll and sizing roll must be adjusted once, and then the most important thing is to adjust the closing plate hole, guide roll and extrusion forming roll of the forming roll. Among them,ريجيناDN32 المجلفن الأنابيبنطاق قابل للتطبيق reducing the edge widening, controlling the edge springback of the finished rolled pipe, and ensuring that the weld is vertical without screwing into the extrusion roll.

Acceptance according to standards

oChatham Kent Welded steel mesh,Products Show is especially suitable for large-area concrete engineering.

wYFirst, we can clean the outer surface of the welded pipe with solvent or emulsion. This method is very effective for cleaning the oil stain, dust and other organic matters on the surface of the welded pipe.
