Versatile Right Angle Rectangular Steel Pipe - Your Reliable OEM, ODM, and Wholesale Solution

In the following usage scenarios of square rectangular tubes, such as mechanical guides, agricultural machinery skeletons, square rectangular tubes for steel and wood furniture, and square rectangular tubes for curtain wall construction, high-precision square rectangular tubes are required due to the need for tolerance fit. Among them, the most important aspect of concern for these customers is the flatness of square rectangular tubes. Therefore, Yuantai Derun Group has specially developed rectangular steel pipes with right angles. At present, the production of square rectangular 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.

The forming technology of right angle/sharp angle square rectangular pipes adopts progressive roller extrusion technology to manufacture 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 steel pipes.

The size range of right angle rectangular steel pipes is: side length 15mmx30mm~1200mmx800mm, wall thickness 0.5mm~60mm;

Mechanical guide rails, agricultural machinery framework, steel and wood furniture, curtain wall construction, large steel structures, mechanical equipment, etc.

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.

Tianjin Yuantai Technology Development Co., Ltd. has 4 production units and more than 50 employees, which undertake large-diameter thick wall rectangular tubes, seamless rectangular tubes, special-shaped tubes, hot-rolled rectangular tubes, square tube specifications of 80 * 80mm-1200 * 1200mm, rectangular tube specifications of 50 * 100mm-1200 * 1500mm, wall thickness of 2.75mm-50 mm, in accordance with the standard GB / t3091-2015, and any specification and material in this range (such as Q235 / q355 / Q390 / Q420 / Q460 / high-strength steel / weathering steel, etc.) can be customized. The outgoing process of hot-rolled right angle pipe is particularly advanced. Two technical methods of on-line hot rolling four corners and overall heating are adopted, which has the advantages of power saving and high efficiency.

Inspection of round pipe (raw material) - feeding - hydraulic propulsion - roll extrusion (round square change) - Inspection of steel pipe (overall dimension, flatness, perpendicularity and R angle) - blanking (inspection of steel pipe straightness and twist) - shaping of mouth end (there will be deformation area at the head end during steel pipe deformation) - sawing and trimming - Inspection and spraying standard - Warehousing

At the "China Building Science Conference and green smart building Expo", the first exhibition of the National Convention and Exhibition Center (Tianjin) held on June 24, 2021, Tianjin yuantaiderun group provided square tube (200) for the construction of the national exhibition × seven hundred × 8mm，200 × seven hundred × 10mm，200 × seven hundred × 12mm，200 × seven hundred × 16mm，200 × eight hundred × 8mm，200 × eight hundred × 10mm，200 × eight hundred × 12mm，200 × eight hundred × 16mm) is mainly used for column structure and supporting structure. The umbrella shaped steel structure of the main body of the main entrance landing Hall of the exhibition hall is made of "yuantaiderun" brand structural steel pipe products.

As we all know, square pipe is a kind of light-weight thin-walled steel pipe with hollow square section, also known as steel cold-formed profile. In addition to wall thickness thickening, the corner size and edge flatness of hot-rolled extra thick wall square pipe reach or even exceed the level of resistance welding cold-formed square pipe. Tianjin yuantaiderun group welcomes customers to actively consult various special-shaped pipe orders to challenge all kinds of impossibility!
