New Vam Connection Thread

NEW VAM thread

Anti-wear and anti-adhesion technology, through the selection of materials and the improvement of surface treatment technology, the problem of thread bonding has been basically solved. The casing is shackled three times and the oil pipe is shackled ten times without bonding; By optimizing the structure to make the joint stress distribution more reasonable, colleagues have developed some steels that are resistant to acid gas corrosion (such as 9cr, 13cr, etc.) for steel pipe production, which greatly improves the corrosion resistance of the street; Mainly through the design of the shoulder structure, it is easier to perform wound operations; 6. The design of the integrated joints meets the application of some small gap cementing, workover and secondary development and production technologies; 7. High temperature resistance, developed Some joints can meet the thermal cycle production needs of high temperature gas injection wells at 350 ° C
