In addition， galvanized steel is more expensive than ordinary steel pipes， so installing them requires a lot of financial costs.
3 The development of steel mesh has met the soft and hard conditions.

Speed up the construction progress: weld the mesh with reinforcement to allow the rapid construction of the project. The required laying of welded steel bars is provided， so concrete can be poured， steel cutting， stitching，Products Show etc.，Saint - VincentCombien coûte 20 poutres I par mètreMéthode expérimentale and the arrangement can be strengthened. ？ saving construction time? The construction progress is greatly accelerated and the construction period is shortened.
DKanta 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.
GdGenerally what are the customers requirements and standards during acceptance? When the galvanized pipe is accepted， you can judge whether it is qualified from the appearance， or whether there are problems such as missing plating or bubbles on the outer wall of the whole square pipe. Only by solving these problems in time can it be judged as qualified and better used.
Classification by section shape
Galvanized pipes are used in construction， machinery manufacturing， steel construction and other projects， shipbuilding， steel structure engineering， power engineering，Products Show power plant， agricultural and chemical machinery， glass curtain wall， automobile chassis， boiler construction， highway railing， house construction pressure vessel， oil storage tank， bridge， power plant equipment，Products Show Hoisting and transportation machinery and other welded structural parts with high load.
u→ I-beam can be processed into T-beam， and honeycomb beam can be combined to form various section forms，Saint - VincentCombien coûte 20 poutres I par mètreMéthode expérimentale which greatly meets the needs of engineering design and manufacturing.
TWelded pipe refers to the steel pipe with joints on the surface， which is welded after the steel strip or steel plate is bent and deformed into circular， square and other shapes. The blank used for welded pipe is steel plate or steel strip. How can the steel strip or steel plate be welded together， and what are the welding skills?
DManagement Department The weight of seamless pipe is light， and its weight is only one fifth of that of anti steel.
zK Sulfur is a harmful impurity in steel. Steel with high sulfur content is easy to embrittle during pressure processing at high temperature， which is usually called thermal embrittlement
First， 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，Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd one end is supported on the cantilever beam of side pier， and the other end is supported on the special buttress on the embankment， which is to avoid widening the abutment.
Installation of galvanized pipe and precautions
Production departmenthThe 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， channel steel， square tube， etc; Handles and hinges can also be installed on the reinforcement mesh that needs to be moved or opened frequently.
QThe utility model has the advantages that the axial force of the roll is small， the axial movement is small and the working slope is not required，
Galvanized 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， cold bending and high-frequency welding. In addition to wall thickness thickening， 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， weldability cold and hot workability and corrosion resistance， and good low temperature toughness.
