Installing the pipe structure means the complexity of some elements.
4Galvanized 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.
oGiguaniDue to the relatively high and narrow section size of ordinary I-beam and light I-beam， the moment of inertia of the two main sleeves of the section is quite different， which makes it very limited in the scope of application. The use of I-beam shall be selected according to the requirements of design drawings.
Acceptance according to standards
OPanamaWelded pipes with large or thick diameter are usually made of steel blank immediately， while small welded pipes and thick wall welded pipes must only be welded immediately according to nylon tape. After simple grinding and polishing， metal wire drawing is OK.
WoGalvanized pipes shall be stored in dustproofto keep clean and new . As a professional manufacturer of galvanized pipe，Products Show we have produced galvanized pipe products for many years. Welcome friends who need to buy.
Seamless tube has high elasticity，San José serras LajasCombien coûte la tonne d'acier I?Production stable et ordonnée can be reused on mechanical equipment， no deformation， anti-static.
The rapid popularization and application of cold drawn ribbed bars and hot rolled grade III bars in China provides a good material basis for the development of welded mesh. The formal implementation of welding net product standards and application procedures has played a positive role in product quality and accelerating popularization and application.
lClassification introduction
AWelded pipes with large or thick diameter are usually made of steel blank immediately， while small welded pipes and thick wall welded pipes must only be welded immediately according to nylon tape. After simple grinding and polishing， metal wire drawing is OK.
LRespect for customers 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. Galvanized pipe is widely used in architecture. This product must have been seen by everyone. However there are many types of it. When you buy it， you should also find out which one you need. The reason why it is favored by everyone in the market is inseparable from its advantages. Next， Xiaobian will lead you to see the advantages of galvanized pipe.
qTThe smooth of steel pipe is mainly through tension reducing， which is a continuous rolling process of hollow base metal without center and tip. Under the condition of ensuring the capillary welding quality，Products Show the whole welded pipe is heated to more than ℃ by the welded pipe tension reduction process， and then rolled to finished pipes with various outer diameters and wall thicknesses by the tension reduction machine ( times in total). The fluid pipes produced by developed countries in the world have adopted the welded pipe smooth process in a large number of boiler pipes. With the development of society， Domestic hot welded pipe has gradually formed a situation to replace smooth pipe.
First， the wall thickness of high-quality and smooth steel is particularly thick. Because the thicker the wall thickness of the product， the higher the economy and practicability. The thinner the wall thickness， the greater the processing cost and opportunity， and the higher the resource cost. Secondly， the process of smooth steel also determines its limitations. Generally， smooth steel has low precision， uneven wall thickness，Products Show low brightness inside and outside the pipe， high length cost，San José serras LajasCombien coûte la tonne d'acier I?Production stable et ordonnée pockmarks in the internal appearance， and black spots are not easy to remove. Again， the inspection and shaping need to be processed offline. Therefore it has its advantages in high pressure， high strength and mechanical structure materials. In the process of use， we will gradually find out. In fact， seamless pipe has also entered the market in recent years. With the growth of market demand， the advantages of seamless pipe have also been stimulated. But there are also many fakes and fake products on the market. Be careful when you choose.
Pipe installation:
safety requirements aExternal steel bonding reinforcement method is a more traditional reinforcement method. The utility model uses an adhesive to paste the steel plate or reinforcement mesh on the cracked part of the wall to achieve the purpose of reinforcement. The commonly used adhesive is usually epoxy resin. This method is simple and fast in construction and has little impact on production and life. Basically， the bearing capacity of the wall can be greatly improved without changing the shape and internal use space of the components. It is mainly applicable to the reinforcement of walls that do not allow to increase the section size of original components，Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd but can greatly increase the section bearing capacity.
X Hot hole breaking cold rolling method. This method is dominated by expansion and expands vertical sliding and skew rolling. The former one is mainly cold rolling by relatively limited mandrel mill， cold rolling by few station mandrel mill， the advantages of high efficiency， low metal material consumption， small types， multi specifications and high precision. Therefore， it is widely used
Classification by wall thickness
rGiguaniThey do not need to protect them from mechanical damage.
wUIn building construction engineering， 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.
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.
