Stainless Steel 304 Seamless Pipe Cap–ASME B16.9

Product Description

Pipe fittings welded on the pipe end or installed on the external thread of the pipe end to cover the pipe

Stainless steel pipe cap is also called plug or head. The pipe cap includes the design of convex pipe cap, conical shell, reducing section, flat cap and tight mouth.

Attention

During splicing, only radial and circumferential weld directions are allowed. This requirement may be canceled in the future for large pipecaps. The splicing distance shall be more than 3 t shall not be less than 100mm (the welding heat affected zone is a high stress zoneand the chemical composition in this zone wil be burned. Thereore. t is necessary to avoid the high stress zone. which is related to thethickness. According to practical experience, the stress attenuation length is greater than 3 6,And not less than 100mm).

However.refrigeration equipment is dificult to meet this requirement, which has its particularity.100% radiographic or ulrasonic testing shall be carried out on the splicing weld of the formed head after splicing, and the qualification leveshal follow the equipment shel. The inspection level and proportion of the final formed weld are the same as that of the equipment shel.which is high waste.

For example,if the equipment shell is 20% tested, ll is gualifed. The but weld and final weld of the bukhead are also qualified as ll, and
the welding joint coefficient is 0.85.
if the equipment shel is 100% tested, Il is qualified. The but weld and the final weld of the bukhead are also l qualified, and the weldingjoint coefficient is 1
Therefore, although the bulkhead splicing is 100% tested, the qualification level is different, which follows the equipment shel.But pay attention to the process and manufacturing process:
The correct method is: blanking (scribing) - small plates assembled into large plates - forming - NDT
If the inspection is not conducted before forming, it is wrong to ensure that it is stll qualified after forming. That is to say, NDT refers to the final NDT.
