SS Serious Sliding Sleeve SS系列滑套
General Description: SS Serious Sliding Sleeve is an open-close controlling device for tubing and casing pass.The open and close of core axes of sliding sleeve is realized by standard slickline operation.It is a device for zonal production of oil and gas well.
SS系列滑套是一种油、套通道的开关控制工具。它是通过标准 的钢丝作业来实现对滑套芯轴的打开与关闭，是一种油、气井 完井中分层开采的工具。
SS Serious Sliding Sleeve SS系列滑套
Features: 1.it has large flow cross-section;the flow area is not smaller than the tubing flow area, so the flow resistance is reduced. 2.the balance port is designed for the sliding core axes in order to equalize tubing and casing pressure while it opens and closes,and the sealing element is so protected from been damaged. 3. there are locking structures at opening, equalizing and closing position; 4.Body material can be 4140、4130 or 13Cr. 5. standard locking and sealing structure are designed at the top; 6. it is general design and suitable for standard slickline operation. 7. it has two openning direction for customer choosing. 8. the upper and bottom thread can adjusted according to customer requirement.
