    • The invention relates to a process for checking a hollow body section, wherein the section, after being filled with a fluid, is subjected to a bursting test to demonstrate its brittle fracture resistance. After the open ends of the section are closed, the required bursting pressure is applied by the dynamic movement toward each other of two elements that reach in a sealing manner through the open ends. The dynamic movement of the two elements is achieved by accelerating a weight toward one of the two elements such that the weight impacts the one of the two elements at an impact velocity, causing the dynamic movement.

    • In a process for producing welded steel pipes, a pipe is molded cold from a TM-rolled sheet, welded together and sized to the desired diameter, whereby the sheet includes steel with (in wt. %) 0.02 to 0.20% carbon, 0.05 to 0.50% silicon, 0.50 to 2.50% manganese, 0.003 to 0.06% aluminum, the remainder being iron with potentially other production-related impurities. After welding and sizing, the pipe is subjected to a heat treatment process at a temperature of 100-300° C. and for a holding time that is suited to the thickness of the pipe wall, with subsequent cooling with air or by forced cooling. The resulting pipe is resistant to aging and has sufficiently integral deformation reserve against fracturing with the same high degree of strength, without exceeding the upper limit for the ratio of yield strength to tensile stress according to the current industry standards for conventional steels.
    • 在焊接钢管的制造方法中,将管子从TM轧制板冷成型,焊接在一起并定尺寸至所需的直径,由此该钢板包括含有(以重量%计)的0.02至0.20%的碳,0.05至 0.50%的硅,0.50〜2.50%的锰,0.003〜0.06%的铝,其余的是具有潜在的与生产有关的杂质的铁。 在焊接和上浆之后,将管道在100-300℃的温度下进行热处理,并且对于适合于管壁厚度的保持时间,随后用空气冷却或通过强制冷却进行热处理。 所得到的管材耐老化,具有足够的变形储备,具有相同的高强度的压裂,而不超过根据现有工业标准对常规钢的屈服强度与拉伸应力的比的上限。
