GreenWell coated premium connection ТМК UP PF certified under ISO 13679 CAL IV
TMK, one of the world's leading producers of tubular products for the oil and gas industry, has run ISO 13679:2002 CAL IV tests on the premium connection ТМК UP PF with lubricant-free coating GreenWell.
The tests were conducted at TMK's R&D centre in Houston and were observed by Texas International Engineering Consultants as an independent third party. All samples successfully passed abrasion resistance, gas tightness and ultimate load tests. The successful ISO 13679:2002 CAL IV tests of TMK's pipe products testify to their quality that allows oil and gas companies use them for both onshore and offshore drilling and production projects in challenging environments.
TMK introduced the GreenWell lubricant-free coating technology last year. Polymer coating is a cutting-edge alternative to standard lubricants for threaded connections that ensures gas tightness of pipe connections along with compliance with environmental regulations and safer operating conditions.
