Particularity of carbon steel cap

  The direction of weld seam is only radial and circumferential when stitching. After Carbon Steel Pipe Fitting Caps may cancel this request. The splicing distance should be greater than 3 and not less than 100mm (the welding heat affected zone is a high stress zone, and the chemical composition in the zone will be burnt. Therefore, to avoid the high stress zone, the area is related to the thickness. According to the practical experience, the stress attenuation length is greater than 3, and not less than 100mm. But refrigeration equipment is difficult to achieve this requirement, has its particularity.
