Mixed pass system. According to the characteristics of rolling mills and products, in order to give full play to the advantages of their respective systems and overcome their disadvantages, that is, the combination of more than two systems. For example, straight leg cross rolling pass system is adopted for finished hole and front hole of finished product, and bent leg cross rolling system is adopted for other passes; or direct rolling system is adopted for rough rolling hole and straight rolling system is adopted for the last ~ finish rolling holes Leg oblique tie hole, etc.Requirements of alloy tubes for low and medium pressure boilershamburger, Quality requirementsKey technical characteristics of alloy pipeBattaramulla,Alloy pipes can be used for heating (cooling) projects.Its heat sealing effect is remarkable. It can be directly buried immediately, which can not only save resources but also reduce consumption, not occupy the natural environment, but also purify the environment. The transportation of gas can meet the requirements of long-distance transportation, prevent actual operation and maintenance, meet the requirements of thermal insulation and cold protection, reduce heating equipment, unique and convenient installation, and reduce the construction cycle time of the project. On the whole, it is more convenient to use. It can also be used for the transportation of floor heating and hot springs. Direct rolling pass system. The direct rolling pass system refers to the pass system in which the two open legs of the I-beam pass are on the same side of the roll axis at the same time and the waist is parallel to the roll axis.

Alloy pipes can be used for heating (cooling) projects. The vertical of the processed reinforcement bar shall be divided into small sections as required.→ compared with the concrete structure, the I-steel structure can increase the service area by %,hamburger13crmo4-5 alloy pipe, reduce the self weight of the structure by % - %, and reduce the structural design internal force.safety requirements ,I-beam is mainly used in building structure,hamburger45 large diameter seamless pipe, curtain wall engineering mechanical equipment and vehicle manufacturing.Plan option : Martensitic chromium alloy pipe,The crack mainly occurs at -mm from the edge of the alloy pipe. The shape is several parallel vertical cracks of different sizes. The regularity is that the thicker the specification and model of the alloy pipe is The wider the width, the more serious the disadvantages.

H-beam is a widely used profile in steel structure buildings. It is different from I-beam. The first is the flange, and the second is that the inner surface of the flange has no inclination, and the upper and lower surfaces are parallel. The section characteristics of H-beam are obviously better than those of traditional I-beam, channel steel and angle steel.recommend,hamburger12Cr1MoV alloy pipe manufacturer,With the development of steel structure buildings, only I-beam is not enough, that is, thickened I-beam, the reporter saw that a pump truck with an arm of meters was standing under the bridge spraying cement on the bridge deck, and more than a dozen workers were nervously carrying out leveling work.X-ray or ultrasonic testing shall be carried out for repair welding of alloy pipe, yibai%sx ray or ultrasonic testing shall be carried out. For the spiral welding of alloy pipes for the transportation of water, wastewater, gas, heating steam and other general liquids, X-ray or ultrasonic testing sampling inspection (%) shall be carried out.hamburger,What is nitriding of alloy pipe Small longitudinal crackAll the cracks occur at -mm away from the edge below the alloy pipe, and the macroeconomic orientation is vertical to the cold rolling orientation, showing a 'high mountain' shape.
