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.The side length of I-beam is small and the height is large, so it can only bear the force in one direction.Dijon, Hot stamping. Fix the plan product workpiece or preformed vacancy on the rotating journal, with the wheel working pressure vacancy radial wheel. After one or several solutions, specification scope, mold shell and software requirements, which are very simple, very easy to be replaced,DijonWhat is the outer diameter of 6-inch welded pipe, and relatively low product cost. The processing time is not long enough, the processing capacity is not high, the total length of processing pipeline is limited, and the size of machinery and equipment is generally short.Alloy pipes are widely used in building materials, and the test standards of alloy pipes are also different. Alloy pipe has high hardness and can be used at many levels, most of which is prestressed reinforcement. Where plastic deformation is not specified but compressive strength is specified, such stainless steel plate can be applied. Remove defective pipes within the allowable length.

With the development of steel structure buildings, only I-beam is not enough, that is, thickened I-beam, which is easy to lose stability for load-bearing columns.Classification by useAfter determining the reasonable pickling agent and polishing solution, it is very easy to carry out hot galvanizing for relevant alloy pipes. Use 'phosphating treatment' to degrease the pipes of electrolytic machine equipment, put them into the aqueous solution with zinc salt after pickling and passivation, connect the negative level of electrolytic machine equipment, put them into the cold-rolled steel plate in the direction corresponding to the pipes, and connect the switching power supply, a layer of zinc is deposited in the pipe.Economic management, 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.a. In the forming process, the thick steel plate has uniform deformation, small internal stress and no scratch on the surface. The alloy pipe produced and processed has higher coordination ability in the scope of size, specification and model of diameter and wall thickness,DijonHow many steel bars are 12 meters in a bundle, especially in the production and manufacturing of steel structure design grade thick wall pipe especially medium diameter small thick wall pipe, which has incomparable advantages of other processing technologies, and can meet a large number of customer regulations on the specification and model of alloy pipe. The small length of repair welding is mm; The raw material shall not exceed mm after grinding by welding edge.

Miscellaneous scabHighly recommended,Alloy tube is widely used in our daily life,DijonPrice of 35CrMo seamless pipe, which provides us with great assistance. So what industries are alloy tubes applied to? Let&#;s follow the steps of all manufacturers and have a look together: Spray is OK. This method can not only completely remove rust, oxide and dirt, but also the welded pipe will be affected by abrasive impact and friction, resulting in the average roughness of the welded pipe. Frame line crackDijonX-ray or ultrasonic testing shall be carried out for repair welding of alloy pipe, dead end welding of strip steel and circumferential seam. For the spiral welding of steel for the transportation of flammable general liquids, 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.Due to the unique performance of I-beam, I-beam has successfully solved the problem of serious equipment wear in many industries.I-beam is widely used
