Keep the combustion supporting gas and use it reasonably to avoid fracture of the welding interface. Problems in the welding of steel wire mesh skeleton composite pipe are common， which should be prevented or solved.
6Galvanized 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.

FGuidole The zinc coating is thick， the crystallization is detailed， and the corrosion resistance is excellent;
FeThe electric welding reinforcement mesh can reduce the damage and consumption to the reinforcement processing process. According to statistics， after deducting the steel consumption increased by unit lapping， it can also save about % of the steel. After it is transported to the site according to the construction degree of the project， it can be hoisted to the working face. There is no need to set a reinforcement processing site on the site， which saves the site and increases the management level of the site. At the same time， it can also solve the problems of noise pollution caused by straightening reinforcement.
The advantage of the reinforcement mesh system is ecological. It is filled with natural stone materials. There is a gap between the stone materials to allow plants to grow in it. It can also plant plants on it. It has the dual effects of engineering slope protection and plant slope protection. The Ecological Grid mat is a combination with a height of cm ~ cm， mostly a multi grid box separated by spacer mesh.
Steel transfers heat excellently; Can withstand high temperature; Strong and strong materials; Probably a long time ago. In addition，Products Show and the second is that the inner surface of the flange has no inclination， and the upper and lower surfaces are parallel. The section characteristics of H-beam are obviously better than those of traditional I-beam， channel steel and angle steel.
CIn our daily life and work， among many steel products， the figure of galvanized pipe is particularly prominent. This is because this kind of pipe will be applied to many engineering construction we often see in our life. There are also countless products processed with this kind of pipe. For example， in the field of mechanical equipment processing we often see， the application of galvanized pipe is more frequent. Let&#;s discuss the application scope of this kind of pipe today.

sGPackaging: Welding nets are generally packaged in paper (mostly gray white， yellow， etc.)， some similar to welding wire diameter welding nets， agriculture， construction， transportation， mining and other industries. Such as machine shields animal fences， flower and tree fences， window fences， aisle fences， poultry cages， baskets and decorations.
When the end span plate is connected with the concrete beam for structural reinforcement， the length of the surface mesh reinforcement extending into the beam shall not be less than d. When the beam width is small， the extended reinforcement shall be bent . When the perimeter of the floor is poured integrally with the concrete beam or wall， the length of the surface mesh reinforcement extending into the beam shall not be less than the anchorage length of the small reinforcement required by the standard (without transverse reinforcement) when the beam width is small， the extended reinforcement shall be bent.
Galvanized pipes are designed to maintain high enough corrosion resistance.
Variable costxLongitudinal welded pipe has the advantages of simple production process， high production efficiency， low cost and rapid development. The strength of spiral welded pipe is generally higher than that of straight welded pipe. It can produce welded pipe with larger pipe diameter with narrow blank， and welded pipe with different pipe diameter with blank of the same width. However， compared with the straight seam pipe with the same length， and the production speed is low. Welded pipes with large or thick diameter are generally made of steel blank directly， wire drawing is OK. Welded pipe is welded with strip steel， so it is not as high as seamless pipe in its original position. Welded pipe process: uncoiling of raw materials - leveling - end shearing and welding - looper - forming - Welding - removal of internal and external weld beads - pre correction - induction heat treatment - sizing and straightening - eddy current testing - cutting - hydraulic inspection - Pickling - Inspection (strict control) - Packaging - delivery.
UThe side length of I-beam is small and the height is large， so it can only bear the force in one direction.
The reinforcement on both sides of the inverted beam extends into the beam respectively， and the anchorage length of the reinforcement is the same as that of the reinforcement， without hook.
lWest BayIn order to strengthen the "muscles and bones" of the bridge， the construction party specially paved two layers of reinforcement mesh before pouring cement.
cB Spiral welded steel pipe (sy- for pile is made of hot-rolled steel strip coil as pipe blank， often warm spiral forming， double-sided submerged arc welding or high-frequency welding. It is used for foundation pile of civil building structure， wharf， bridge， etc.
After hot-dip galvanizing of steel structure， it is equivalent to one-time annealing treatment， which can effectively improve the mechanicalof steel matrix， eliminate the stress during steel forming and welding， and is conducive to turning of steel structure.
