Interpipe has certified its premium tight gas threaded joints UPJ-M for the correspondence to ISO 13679 CAL IV.
“The certificate confirms the correspondence of the joints to the highest level of requirements. The tests have been carried out in Italy”, the company said in a statement.
The UPJ-M joints can be used in the most extreme conditions, while the corrosion-resistant steel allows their use in environment with high contents of carbon dioxide and hydrogen sulfide.
CAL IV joints are the obligatory requirement in many oil and gas projects in the Near East, Asia-Pacific Region, Latin and Central America and CIS. (Ukrainian metal)
