Seamless Pipe Cap VS Welded Pipe Cap

Both seamless pipe cap and welded pipe cap are commonly used, so do you know what are their differences?

1. Produce process.
2. Surface: Welded cap have a welded joint at the surface, while seamless pip cap does not.
3. Marking: For example, a ASTM A234 WP9 CL1 pipe cap, the grades marking will be “ASTM A234 WP9 CL1” if it is seamless, if welded, it will be marked as “ASTM A234 WP9 CL1W”.
4. Application: Seamless pipe fittings can bear higher pressure than welded pipe fittings, so seamless cap always applied in high pressure applications while welded cap is mainly for medium and low pressure applications.
