Interpipe international vertically integrated pipe and wheel company has completed CAL IV certification of own Ukrainian Premium Joint (UPJ-M) gas tight coupled and threaded connection for OCTG pipes (Oil Country Tubular Goods) meeting ISO 13679 standard of CAL IV level, the company said. At the same time, as gas and oil are more often produced in the complex geological conditions, the wells become not only obliquely directed, but also horizontal, which results in the toughened requirements to the pipes. Threaded connections play the key role in the reliable operation of pipes in a well.
The obtained certification confirms the correspondence of the Interpipe UPJ-M threaded connection to the highest level of CAL IV requirements (CAL – connection application level). Qualification tests were held in Italy.
Connection type CAL IV is a mandatory requirement in many oil and gas projects in the Middle East, Asia-Pacific, Latin and Central Americas and the CIS. The presence of this connection will allow the company to meet the technical requirements of previously inaccessible projects.
