Walled precision light pipe, Jining precision light pipe, pipe industry virtues

 Pipe straightness: seamless steel pipe, straight seam steel pipe reproduction process will lead to the tube with varying degrees of curved steel cold rolled precision light in the vertical, and some can be seen with the naked eye bright cold drawn precision steel tubes, which are substandard products. Regular manufacturers have dedicated their straightness measuring instrument, the factory does not allow unqualified. The numbers indicate the degree of curve is called out of steel pipe bending and straightness, for this standard, general fluid pipes do not ask, but is used in machining, the request will be high, especially thick rubber roller precision light pipe, axis. Seamless steel pipe production process there is a three-roll straightening process, can basically meet the requirements of customers for straightness. There are two general linear calculation: a. Local curvature: a meter with a long ruler against the maximum bend steel, measuring its chord. Is the local curvature values. II. The total curvature of the total length of pipe: with a string tension from both ends of the tube, precision light pipe, pipe bend test its maximum chord, and then converted into a length (m) the percentage of full-length is the length of the curved pipe degrees. Small-caliber precision light pipe welding distortion correction How? Here are some correction method of small-caliber precision light pipe welding deformation: the small-caliber precision light pipe welding distortion correction often used mechanical methods. For deformed thin shell structure and rules from long butt weld caused by welding and steel wheels rolling on both sides, get a good correction. Use of local heating compressive plastic deformation so long weldment after cooling contraction Flame straightening, with highly mobile, the advantages of simple equipment, has been widely adopted. Small-caliber precision light pipe welding deformation size and weld size, number and arrangement of related. First, reasonably determine the number of welds from the design, the small diameter precision light pipe groove shape and dimensions, and location of the weld properly arranged, is very important to reduce distortion. In the process using a high energy density welding process parameters of the method and a small heat input, such as multi-layer welding to reduce the longitudinal weld, flexural and transverse shrinkage and deformation of the resulting instability is advantageous. However, for multi-layer welding angular distortion disadvantage. Using reasonable assembly, welding sequence, anti-deformation and rigid fixation can reduce small-caliber precision light pipe welding deformation.
