Float Valve & Float Sub
API standard drill pipe Float valve is one of necessary tool for drilling, it consists of float valve sub and float valve, the main function are to prevent drill cuttings come into mud when connecting each joint and the bit bore block caused by back flow of silt.
-
Engineered with precision and designed to regulate fluid flow, our high-quality float valves ensure optimal performance and dependable sealing. Crafted from durable materials, these valves offer superior resistance to corrosion, abrasion, and harsh operating conditions. With their innovative design and advanced functionality, float valves play a vital role in preventing backflow, maintaining pressure control, and enhancing safety in oilfield operations. Trust in our float valve solutions to optimize fluid control, increase efficiency, and achieve smooth-running operations in your oilfield projects.
1.1 Plunger-type float valves:
The Model F is a plunger-type float valve that provides a positive instantaneous shut off, providing constant fluid control while drilling. The Model F is a reliable and economical selection under standard drilling operations.1.2 Flapper-type float valves:
The Model G is a flapper-type float valve that, when opened, offers an unobstructed bore through the float valve. The uniquely designed flapper closes rapidly to prevent shavings from entering the drill string when circulation stops and also assists primary BOP equipment in maintaining internal pressure control. The valve will fully open when the first joint is raised from the hole, preventing pulling wet joints. -

Top Drive Saver Sub
Top drive subs are a pin-by-pin sub that is made up to the top drive, they serve as the sacrificial element between the drill string and the top drive. This saves on costly repair to the top drive by allowing multiple connections to be made up and broke out using the sub rather than the top drive itself.¥ 0.00Details
-
Wear Sub
During drilling operation, serious wear often takes place between drill pipes and casings. The wear sub is typically placed above the drill bit. It is designed to withstand the abrasive forces encountered during drilling, such as formations with high rock hardness or high levels of drill bit vibration.¥ 0.00Details
-
Torque Reduction Sub
Torque reduction sub is to reduce the excessive torque generated by drilling in short radius horizontal section and large angle well section. According to its structural components, the torque reduction sub is divided into: mandrel body, upper and lower sliding bearings, slip spiral inner sleeve, straight rib outer sleeve, stop collar etc.¥ 0.00Details
-
Crossover Sub
Crossover sub is a short sub assembly used to enable two components with different thread types or sizes to be connected. Also it can be used to protect other tooling in drill stem (called saver sub) or be used to deliver outgoing air to the bit face just above the bit (called bit sub).¥ 0.00Details
