Metric welded pipe: it is used as seamless pipe in standard. The welded steel pipe expressed by outer diameter * wall thickness mm is welded by hot and cold strip welding of general carbon steel， high-quality carbon steel or Puneng low alloy steel， or it is made by cold drawing after hot strip welding. Metric welded pipe is generally used as structural parts， such as transmission shaft， or to transport fluid. The thin wall is used to produce furniture and lamps. It is necessary to ensure the strength and zigzag test of steel pipe.
0The two ends of the steel produced by the seamless pipe manufacturer shall be cut into right angles， and the burrs on the surface shall be removed，Products Show which is the raw material used by the seamless pipe manufacturer. The embryo prototube embryo needs to be cut by a cutting machine to form an embryo material with a length of about one meter，CubaAlloy pipe gh1016How is the application concept which is sent to the furnace for heating through the conveyor belt. The billet is sent to the furnace. After internal heating， the temperature is about degrees， and the fuel used is often ethyne. Temperature control in the furnace is a very key factor.
cHavana Dry processing technology: after passivation treatment， parts shall be dried with air compression or hot gas， or drying treatment or air drying can be selected.
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.
Wminister Sulfur is a harmful impurity in steel. Steel with high sulfur content is easy to embrittle during pressure processing at high temperature，Products Show which is usually called thermal embrittlement

Platform reinforcement mesh is a widely used reinforcement mesh product， such as industrial maintenance platform， berm， etc. this kind of reinforcement mesh is widely used in industry， municipal administration， electric power，Products Show coal mine and other fields， and has the strongest resistance to surface impact，CubaAlloy pipe gh1016How is the application concept especially the reinforcement mesh with a cross bar spacing of mm has a strong ability to resist lateral impact.
External 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， but can greatly increase the section bearing capacity.
rBecause alloy pipe is a very unique pipe fitting， we must use appropriate methods to carry out installation in the case of installation， so as to ensure the performance index of the data. Generally when installing alloy pipes， we will use some flanges and elbows to fix them， so as to ensure that the raw materials can be fixed very well. Therefore， when we carry out use，Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd so as to ensure the actual effect of alloy pipe assembly. If there are instrument panel components that must be assembled on the pipeline， they must be installed together.
IThe correct and reasonable use of galvanized pipe can play a better role. The product can be widely used in the market because of its obvious performance advantages. Both strength and toughness are worth our choice. Let&#;s see what the specific uses are and what the acceptance standards are?
Paverage methodThe 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.
cSGalvanized pipe: the zinc layer of cold galvanized pipe is an electroplating layer， and the zinc layer is separated from the steel pipe substrate. The zinc layer is very thin. The zinc layer is simply attached to the steel pipe substrate and is easy to fall off. Therefore， its corrosion resistance is poor. In new homes， it is forbidden to use cold galvanized pipes as water supply pipes.
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.
Polished stainless steel pipes shall be subject to internal inspection and strict manual selection by the steel pipe quality inspector through metal detector (or hydrostatic test) and qualified products shall be packaged and delivered.
High quality and low pricekThe 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， and specifications and procedures were formulated.
EThe import and export order of I-beam is generally based on the specifications required in use after determining the corresponding carbon structure steel (or low alloy steel) steel grade. Except for the specification number， I-beam has no specific composition and performance series.
Silicon; it can improve the hardness of steel， but the plasticity and toughness decrease. Electrical steel contains a certain amount of silicon， weaken and eliminate the adverse effects of sulfur， and improve the hardenability of steel. High alloy steel (high manganese steel) with high manganese content has good wear resistance and other physical properties
Seamless pipe is a long steel with hollow section and no joints around it. There are more than production plants under more than companies in more than countries producing seamless pipes， including more than plants under more than companies in countries.
