Connections are machined in full compliance with API 5CT and API 7-1 standards.

These connections are cut with standard materials like AISI 4140/L80 or AISI 4145. We can also supply these cuts with special materials based on customer needs.

Inspections include gauging, hardness survey, dimensional inspection, and NDT performed internally. Third-party inspection can be arranged on request. 

We can phosphate coat or blast prepare the external surface for the recommended paint system. All connections carry thread protectors as required by the governing specifications. 

We repair/refurbish ours and other OEM API 5CT / API 7-1 crossover/pup joints at our facility or in situ (depending upon volume). 

We manufacture API 7-1 products like rotary shoulder connections, saver sub, lift sub, bit sub, circulating sub, side-entry sub, blanking sub, crossover sub, rotary sub, pump-in sub and pup joint with thread profiles like internal flush (IF)/ full hole (FH)/ regular (REG) 

We manufacture API 5CT products like casing/tubing connections, crossover sub, saver sub, lift sub, blanking sub, and pup joint with thread profiles like long round thread casing (LTC), short round thread casing (STC), buttress thread casing (BTC), external upset tubing (EU), non-upset tubing (NUE), line pipe (LP) and national pipe thread taper (NPT) thread profiles.
