  The Stainless Steel Caps is welded on the pipe end or on the outer thread of the pipe end to cover the pipes of the pipe,Used to seal the pipe.

  ANSI Seamless Pipe Fitting Stainless Steel Cap can avoid splicing, which will reduce the thickness and stress.

  Welding direction is only allowed to be radial and circumferential when splicing. Future Stainless Steel Caps may cancel this requirement. The distance required for splicing shall be greater than 3 100mm, and the heat affected zone is a high stress zone, and the chemical composition of the zone will be burned. Therefore, to avoid high stress area, the area is related to thickness. According to practical experience, the stress attenuation length is greater than 3 100mm and is not less than 0. But refrigeration equipment is difficult to achieve this requirement, and has its particularity.

  After splicing, the welded joints should be examined by 100% or ultrasonic waves. The qualification level will follow the case. The final weld inspection level and proportion are the same as that of the equipment shell, which is high waste.
