. 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).

5 Pickling: if the material cannot be removed after cleaning, pickling will be selected. Pickling of galvanized pipe is divided into chemical and electrolytic. How to prevent white rust of galvanized seamless steel pipe? It has a certain anti-corrosion effect on the pipeline.

jrenaultAlloy tube is widely used in our daily life, which provides us with great assistance.

According to the pipe wall thickness, pipes made of relatively thin materials such as steel strip can be welded with high frequency, and some thin-walled pipes can be welded with shielding gas; Pipes with wall thickness more than mm can be welded by hand.

UMalacca Seamless tube has high elasticity,Products Show can be reused on mechanical equipment,Louisville16Mn large diameter longitudinal welded pipeHow to choose a good one no memory, no deformation, anti-static.

CdThe reinforcement mesh of the maintenance platform has the characteristics of extensive application, beautiful style, convenient installation and durability, Skirting plate (edge guard plate), checkered plate 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,Products Show channel steel, square tube, etc; Handles and hinges can also be installed on the reinforcement mesh that needs to be moved or opened frequently.

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.

xWhen it is used for ground heating and hot spring transportation, it can meet the requirements of refrigeration and achieve the practical effect of less damage. It is applicable to water conservancy engineering, cold and corrosion prevention. In addition, the chemical raw material transmission pipeline has a wide indoor space.

SAcceptance according to standards

EFocus on DevelopmentFirst, the two hole beam end space on the pier top shall be used to set the cast-in-situ transverse cantilever cantilever beam, on which the prefabricated micro bending plate shall be installed. The second is to erect prefabricated sidewalk beams in the cantilever part of the cantilever beam. The sidewalk beams of bridge openings on both sides are longer than the main beam,Products Show one end is supported on the cantilever beam of side pier, and the other end is supported on the special buttress on the embankment,Louisville16Mn large diameter longitudinal welded pipeHow to choose a good one which is to avoid widening the abutment.

oIIn order to improve the corrosion resistance of steel pipe, the general steel pipe (black pipe) is galvanized. The galvanized pipe is divided into hot-dip galvanizing and electric steel zinc. The hot-dip galvanizing layer is thick and the cost of electric galvanizing is low so there is galvanized pipe.

Simple section steel pipe -- circular steel pipe, square steel pipe, oval steel pipe, triangular steel pipe, hexagonal steel pipe, rhombic steel pipe, octagonal steel pipe,Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd semi-circular steel pipe, others.

Operating conditions

Safety productionqGalvanized pipe is a kind of light thin-walled steel pipe with hollow square section, also known as steel cold-formed profile. It is a section steel with square section shape and size which is made of Q hot-rolled or cold-rolled strip or coil as the base material, the corner size and edge flatness of hot rolled extra thick wall galvanized pipe reach or even exceed the level of resistance welding cold formed galvanized pipe. Good comprehensive mechanical properties, cold and hot workability and corrosion resistance, and good low temperature toughness.

UFunction of I-beam: where is I-beam mainly used?

Filling: welded pipe is welded by electric welding of hot-rolled strip steel, so its influence was not as high as that of seamless steel pipe.

nrenaultWhen excavating a tunnel in a stratum where the rock is not hard and complete, it is generally necessary to excavate a diversion pit (also known as pilot hole) and set temporary support.
