The utility model has the advantages that the axial force of the roll is small, the axial movement is small, and the working slope is not required,When selecting I-beam in structural design, reasonable I-beam shall be selected according to its mechanical properties,LantianQuotation of I-beam cold bending machine, chemical properties, Completion of pipeline trench ground; Bricklaying of pipe shaft is completed.So why is the alloy pipe easy to rust after being pickled and passivated by the software?Homa Bay,Introduction to product knowledge of alloy pipe:The wear resistance, fracture toughness, impact toughness and bending strength under different process conditions were compared and then the heat treatment process of GCrMo was determined. Development and application of ZYS- bearing damping and antirust oil. Bearing is a new type of multial damping and antirust oil. It takes refined mineral oil as the base oil and is equipped with various additives such as antirust and antifriction. Through comparison test, matching test with lubricating grease and user test, it is proved that ZYS- bearing damping and antirust oil has outstanding damping effect and good antirust lubrication performance.I-beam has the dual properties of high hardness and toughness materials. Compared with other engineering wear-resistant materials in China such as various alloy steel plates, cast wear-resistant plates, rubber, polyurethane,Lantian27SiMn large diameter seamless pipe,Lantian273 welded pipe 1m heavy, etc., it has irreplaceable comprehensive excellent properties.

Alloy pipes can be used for heating (cooling) projects.Identification method of galvanized pipeAt the same height, light I-beam has narrower legs, thinner waist and lighter weight than ordinary I-beam. No. - is large I-beam, and No. - is medium I-beam. Imported I-beam shall be marked with actual specifications, dimensions and relevant standards.OK or not?,The specification of I-beam is expressed in cm of waist width. For example, the waist width of No. I-beam is cm. The types of I-beam include hot-rolled ordinary I-beam Light I-beam and wide parallel leg I-beam (H-beam). The waist width of hot-rolled ordinary I-beam in China is ~ mm, expressed as No. ~ No., and the inclination of inner side wall of leg is : The pass system of rolled I-beam includes direct rolling pass system, I-beam can also adopt special rolling method.Alloy pipes can be used for heating (cooling) projects. Small longitudinal crack

When we carry out different projects, we must use different raw materials, which can ensure the quality of the project. In many kinds of data alloy pipe is widely used. In many projects, we will apply it, so it is very popular in the field. When people carry out the construction of alloy pipe project, there are many things that must be paid special attention to. Let&#;s take you to know:Recommendation and consultation,Alloy pipe can be divided into round steel pipe and special-shaped steel according to different cross-sectional area. Because the circular area is large on the premise of the same side length, a large amount of liquid can be transported with an annular tube. In addition, when the circular cross section bears the internal or external axial working pressure, the bearing force is more symmetrical. Therefore, most seamless steel pipes are round steel pipes.Acceptance according to standards Remove defective pipes within the allowable length.Lantian,At present, there is still a big gap in the production technology of C-section steel between China and foreign countries.Key technical characteristics of alloy pipeWhat is the purpose of flat steel
