How is rectangular steel tubing made?Characteristics and USES of rectangular tube

- Jun 04, 2019-

          Rectangular tube is a kind of hollow strip of steel, also known as flat tube, flat square tube or square flat tube (as the name implies).A large number of pipelines used to transport fluid, such as oil, natural gas, water, gas, steam, in addition, bending resistance, torsional strength at the same time, the weight of light, so also widely used in the manufacture of mechanical parts and engineering structures.Also commonly used for the production of conventional weapons, barrels, shells, etc.

1. Product description of rectangular tube

        Rectangular tube is a hollow square section of light - walled steel pipe, also known as steel cooling bending section.It is Q235 hot or cold rolled strip steel or coil plate as the base material after cold bending processing and forming by high-frequency welding made of square section shape size of section steel.In addition to the thickening of the wall, the dimensions of the corner and the flatness of the edge of the hot rolled extra-thick square pipe are up to or even beyond the level of the resistance welded cold-formed square pipe.

2. rectangular pipe use

       Construction, machinery manufacturing, steel construction projects, shipbuilding, solar power bracket, steel structure engineering, electrical engineering, power plant, agricultural and chemical machinery, glass curtain wall, automobile chassis, airport, etc.

         The utilization rate of seamless moment pipe Q345 is very high, but the general construction side before the construction, the appearance of the pipe, pipe fitting, rubber ring, etc. do a check, found that there are problems to give up the use.

(1) Clean the seamless moment pipe mouth of Q345: scrub and clean all the sundries inside the socket mouth.

(2) clear the apron ring, on the apron ring: clean the adhesive material on the apron ring, turn the apron into "plum shaped" or figure 8 into the socket groove, and press along the entire apron with your hand, or use a rubber hammer to smash, to ensure that all parts of the apron is not twisted, evenly stuck in the groove.

(3) apply lubricant on the outer surface of the socket and the apron: apply the lubricant evenly on the inner surface of the apron installed at the socket and on the outer surface of the socket.

(4) Lower pipe: the seamless moment pipe Q345 shall be lowered to the bottom of the groove according to the requirements of the lower pipe, usually using the manual pipe lowering method or the mechanical pipe lowering method.

(5) Installation of machine and equipment: install the prepared machine and equipment in place, and pay attention not to re-contaminate the cleaned Q345 seamless rectangular pipe.

(6) pusher Q345 seamless torque tube to insert the socket: when installed, in order to insert the pin into more manpower and smoothly in the socket. Port into the socket and the interface of the pressure in the socket of aprons, connect the wire rope and chain, for tension chain; until all the pins inserted into the socket in place, between socket and the socket should stay about 2 mm gap, and ensure the socket around outside along the distance to the aprons.

           In the process of installation, the fixed pipe and moving pipe axis should be in a straight line, otherwise it is easy to push out the rubber ring, affecting the quality and speed of installation.Installation of Q345 seamless moment tube should be flat, Q345 seamless moment tube should be in a straight line, in case of inclination Angle, be careful.Align the interface connecting Q345 seamless moment tube with the socket. If the insertion resistance is too large, do not force the insertion to prevent the rubber ring from twisting.Rubber ring lubricating oil should be used with vegetable oil;Cold winter, the rubber ring can be preheated with hot water to reduce hardness and quickly install.
