Overview of square steel pipes with right angles
The R angle of a right angle square tube is different from a regular circular arc square tube. A right angle square tube is a type of right angle square tube with an R angle not greater than one time the wall thickness. Right angle square tube: When the wall thickness is not greater than 3mm, the R angle is not greater than 1mm; When the wall thickness is 3-8mm, the R angle should not exceed 2mm; When the wall thickness is above 8mm, R is not greater than 3mm as a sharp corner square tube. The square tube process of Yuantai Derun has become very mature in China.
2、 The research and development purpose of square steel pipes with right angles
In real industrial production and life, mechanical guide rails, agricultural machinery skeletons, square pipes for steel and wood furniture, and square pipes for curtain wall construction require high-precision square pipes due to the need for tolerance fit. Among these customers, the flatness of square pipes is the most important aspect. At present, the production of Yuantai Derun right angle square pipes mainly adopts cold drawing and continuous bending of steel plates, and the flatness of ordinary finished steel pipes cannot meet the needs of customers.
3、 Forming Technology of Right Angle Square Tube
Yuantai Derun Steel Pipe Manufacturing Group adopts progressive roll extrusion square technology to process and manufacture right angle square pipes, improving the machining accuracy of work rolls and continuously adjusting the assembly spacing of roll systems, thereby accurately controlling the plane size of finished right angle steel pipes.
1. The square tube is processed and manufactured using progressive roll extrusion technology, and the plane rebound of square tubes of different materials and specifications is collected for variance analysis and experimental design, and the plane rebound curve of square tubes is drawn. (Note: ① Welded right angle square pipes can be made of hot-rolled strip steel, which can be formed by cold bending, or round pipes can be formed into square pipes and then heat treated; ② Seamless right angle square pipes can be made of hot-rolled seamless pipes, which can be directly formed by hot rolling or formed by cold bending.)
2. Based on the theory and practice of roll flattening, design and manufacture rolls with different final rolling convexity required to meet the strength requirements of different materials for production.
3. Strictly control the machining accuracy of the work roll and improve the flatness control accuracy of the finished square tube.
4. By continuously adjusting the assembly spacing of the roller system, it ensures the parallelism of the product relative to the two planes.
who we are?
Tianjin Yuantai Derun group has 18 wholly-owned subsidiaries, of which Tianjin Yuantai Technology Development Co., Ltd. was founded in 2014 to produce super large diameter and super thick wall rectangular tubes, which are scarce in the market. This kind of non-standard pipe is made of longitudinal submerged arc welded pipe or seamless steel pipe as raw material, and the raw material is extruded twice to form a square rectangular pipe meeting the quality requirements. Moreover, Tianjin Yuantai Technology Development Co., Ltd. can also produce various specifications of special-shaped tubes such as right angle tubes, octagonal tubes and trapezoidal tubes, and undertake tempering and annealing processes. With the support of professional technicians and equipment, our next goal is to develop straight out special-shaped tubes.
Produce for our Project

As is well known, right angle square pipes are a special type of square steel pipe with a hollow square cross-section, also known as cold formed steel. In addition to wall thickening, the corner size and edge flatness of hot-rolled extra thick wall square tubes reach or even exceed the level of Electric resistance welding cold-formed square tubes. Tianjin Yuantai Derun Group welcomes customers to actively inquire about various orders for square tubes, challenging various impossibilities! Contact Us
