Galvanized pipe has excellent corrosion resistance. Compared with traditional steel， its application life is longer. Secondly this kind of pipe has strong resistance to baking. In case of critical situation， it will not lead to the collapse of building structure in a short time. In addition， this kind of pipe also has a practical advantage， that is， it is more convenient and lighter when carrying out the construction and installation. The operators save time and labor when carrying out the construction，Products Show and the operation efficiency has been greatly strengthened. In this regard，Belize 18 price of I-beamCorrosion failureysis it is not difficult to understand why the galvanized pipe is so favored by various construction units.
3 General carbon steel wire sleeve (GB / t- is a steel pipe used to protect wires in electrical installation projects such as industrial and civil buildings and installation of machinery and equipment.

Application of galvanized pipe
CMoncrovaIf the steel pipe is not welded well， that is， if it is not welded， the welding conditions of steel mesh skeleton composite pipe shall be provided.
DvIn our daily life and work， we can often see a lot of steel products. At the same time， 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. Lets discuss the application scope of this kind of pipe today.
Steel mesh guardrail (steel mesh fence) steel mesh guardrail refers to the guardrail made of steel mesh. It is stronger and more durable than the guardrail made of electric welding mesh，Products Show hook mesh， etc.， but its cost is much higher， and it is rarely used under normal circumstances
According to the shape of the product， special flour welding or ordinary thread connection shall be used.

M Multi channel cold rolling (cold rolling) process. Cold rolling of steel pipe is carried out on multi roll mill. Stainless steel pipes are rolled with round holes composed of variable cross-section circular grooves and fixed taper.
FWelcome calls The chemical composition of cold-rolled ribbed strip is the same as that of hot-rolled smooth round strip. It is rolled at room temperature with hot-rolled smooth disc strip， which is called cold rolling. Due to the reorganization of steel crystal structure by cold rolling process， ll， ll， etc.) is obtained， which has poor ductility and cannot be welded. If there are double-sided ribs and three-sided ribs，Products Show the specification allows LL to be used as stirrup. The design value of strength is limited to n / mm?.
mCGalvanized pipe can be seen from its name. It is a square pipe type. Many materials can form galvanized pipe body. It is used for what purpose and where. Most galvanized pipes are steel pipes. After unpacking， leveling，Belize 18 price of I-beamCorrosion failureysis they form round pipes， which are rolled into square pipes， and then cut into the required length. Generally， there are galvanized pipes in each package. In terms of spot most of them are in large specifications， decorative galvanized pipes， architectural galvanized pipes， mechanical galvanized pipes， etc.
Check whether the manufacturers qualification，Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd business license， organization code certificate， tax registration certificate， production and operation license and other qualification materials are complete. Look at the case， investigate the suppliers performance and the projects served in the past. Whether there is a self built logistics fleet or not， choosing a service provider with a self built logistics fleet can reduce the transportation cost， and more importantly， ensure the timeliness of delivery. After sales service， whether there is a sound and reliable after-sales service guarantee system， and timely solve quality problems in arrival acceptance and subsequent use. Check whether the quality assurance materials such as product quality certificate， material specification and warranty are complete. Check the appearance of the welded pipe， the surface is smooth and flat， the weld is dense， without burr， oil stain， corrosion， extrusion deformation and flat cross section. Use a micrometer to check whether the outer diameter and wall thickness of the welded pipe meet the requirements， and the standard wall thickness deviation shall not exceed % - %. NDT shall be carried out for welded pipe with flaw detector. Conduct bending tensile strength test according to the requirements， bend the welded pipe for degrees， and there is no crack at the bend.
Pipelines of various specifications and models are complete.

Because of this characteristic seamless pipe is widely used in oil transportation， natural gas， natural gas， water and some solid materials transportation. Smooth steel pipe has strong bending advantages compared with other steel pipes. And the smooth steel pipe is also light in weight. It is a very economical single-sided steel.

uM According to the purpose， the welded pipe has general purpose and high temperature and high pressure. The pipe used in the latter is often special alloy steel. The problem of shrinkage cracks in the welding process and the mechanical properties of the pipe in the heat affected zone must be considered and solved， and the mechanical properties of the pipe in the heat affected zone will not be greatly changed due to the influence of welding operation.
Galvanized pipe: the hot-dip galvanized pipe base plate and molten electroplating solution are combined physically and chemically to form a dense corrosion-resistant structure of zinc iron alloy layer. The alloy layer is integrated with the pure zinc layer and the steel pipe substrate. Therefore， it has strong corrosion resistance.
