Introduction to rectangular tubes: 1. Consumption and manufacturing methods: ① The operating temperature of ordinary boiler tubes is below 450 ℃, and domestic tubes are mainly made of 10 # and 20 # carbon bonded steel hot-rolled tubes or cold drawn tubes. ② High pressure boiler tubes are often in high temperature and high pressure conditions when they are used. Under the action of high-temperature flue gas and water vapor, the tubes will be oxidized and corroded. The steel pipe is required to have high durability

What is seamless rectangular tube? Seamless rectangular tube is a kind of long steel with hollow section and no seam around. The steel pipe has a hollow section, and is widely used as a pipeline to escort fluids, such as oil, natural gas, gas, water and some solid materials. Compared with solid steels such as round steel, steel pipes are lighter when their bending and torsional strength are the same, and they are a kind of steel with economic section,

Concept and classification of rectangular tube: rectangular tube is a kind of light thin-walled steel tube with hollow square section, also known as steel cold-formed section. It is a shape steel with square section and overall dimension made of Q235 hot-rolled or cold-rolled strip or coil as the base material after cold bending and forming and then high-frequency welding. Hot rolled extra thick wall square tube is in the condition of wall thickness increase, and its corner size and edge straightness are up to

Identification method of rectangular tube: 1. Fake and inferior rectangular tubes are easy to fold. Folding is a variety of broken lines formed by the appearance of rectangular tubes, and this defect often runs through the longitudinal direction of the whole product. The reason for folding is that the fake and inferior manufacturers pursue efficiency, and the reduction is too large to produce ears. The folding will occur during the next rolling. The folded products will crack after bending, and the strength of steel will drop greatly. 2. Pseudo

Precautions for rectangular pipe: Q345 seamless rectangular pipe has a very high utilization rate, but the ordinary construction party conducts a visual inspection on pipes, pipe fittings, rubber rings, etc. before construction, and abandons the use of any problems found. 1. Clearing Q345 seamless rectangular pipe orifice: clean all sundries in the socket. 2. Clearing rubber ring and upper rubber ring: clean and wipe the adhesive on the rubber ring

Difference between rectangular pipe and rectangular steel pipe: rectangular pipe is a kind of hollow long steel, also known as flat pipe, flat square pipe or square flat pipe (literally). A large number of pipes are used to escort fluids, such as oil, natural gas, water, gas, steam, etc. In addition, when the bending and torsional strength are the same, the weight is light, so they are also commonly used to manufacture mechanical parts and engineering structures. It is also commonly used for consumption
