Product details
Description：
(1)Absolute pressure control rupture disk, independent of formation pressure, opening pressure is more accurate;
(2)The overall tightness of the casing can be tested by holding the wellhead to high pressure;
(3)Unique delay valve design, reliable opening;
(4)The flow area of the fracturing port is consistent with the equivalent flow area of the casing diameter, and the fracturing construction is easier;
(5)The sliding sleeve is provided with a locking mechanism, once opened, permanently locked, to avoid the risk of sliding sleeve closure caused by pressure fluctuations during fracturing and production;
(6)Conventional cementing operations do not require special cementing plugs and pressure pads.
