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 has 4 production units and more than 50 employees, which undertake large-diameter thick wall right angle rectangular tubes, seamless rectangular tubes, special-shaped tubes, hot-rolled rectangular tubes, square tube specifications of 10 * 10mm-1200 * 1200mm, rectangular tube specifications of 10 * 15mm-1200 * 1500mm, wall thickness of 0.5mm-50 mm, in accordance with the standard GB / t3091-2015、JIS G3466、EN10210、EN10219、AS1163、IS1161、ASTM A500、ASTM A501, and any specification and material in this range (such as Q235 / q355 / Q390 / Q420 / Q460 /S235J0H/S235J2H/S235JRH/S275/S325/S355/S420/S460/STKR 490/STKR 400/SS400/C250/C350/C450 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 special 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 yuantai derun group welcomes customers to actively consult various special-shaped pipe orders to challenge all kinds of impossibility!
