Steel Pipe Cap 168.3*7.11 Thermal insulation and energy saving
Avoid splicing at the r of the disc cap for thinning and high stress.
The weld direction requirements are only radial and circular. This may be removed by large pipe caps. Splsplicing shall be greater than 3 δ, and not less than 100mm (the weld heat impact area is a high stress area with chemical burns in the area. So avoid the high stress area, which is related to the thickness. From practical experience, the stress attenuation length is greater than 3 δ, and not less than 100mm). But the refrigeration equipment is difficult to meet this requirement, which has its particularity.
