Sincerely hope we become long-term partners - Steel pipe & Fittings:

API 5CT Casing and tubing accessory

 

one-piece tubular section used in a pipe string to provide mechanical and pressure integrity within the pipe string and facilitate the performance of some other function required of that pipe string

 

EXAMPLES Crossover connectors, swages, nipples, flow couplings, blast joints, etc.

 

NOTE Accessories exclude the other tubular products specifically defined in this International Standard or products included in other ISO (API) specifications.

 

4.1.6

 

connection

 

threaded assembly of tubular components

 

4.1.7

 

controlled cooling

 

cooling from an elevated temperature in a pre-determined manner to avoid hardening, cracking or internal damage, or to produce a desired microstructure or mechanical properties

 

4.1.8 coupling

 

internally threaded cylinder for joining two lengths of threaded pipe

4.1.12

 

electric-welded pipe

 

pipe having one longitudinal seam formed by electric-resistance or electric-induction welding, without the addition of filler metal, wherein the edges to be welded are mechanically pressed together and the heat for welding is generated by the resistance to flow of electric current

 

4.1.13

 

handling tight

 

sufficiently tight that the coupling cannot be removed except by the use of a wrench

 

4.1.14

 

heat

 

metal produced by a single cycle of a batch melting process
