Float collars and float shoe The float collars and float shoe are used to guide the casing to be put into the hole. It can adjust the floating power of the casing when the casing been laid in. That can certify the qualification of the cementing. The float collars and float shoe manufactured by our company use the spring driving back-pressure valve type. It has a high reliability. The structures are similar between float collar and float shoe. The lower end of the float collar is the pin connection which is connected with the casing. The upper end which is used for filling the cement has acinqfoil hole which can avoid the twist. The material of the float shoe body is the alloy steel . The upper end of the float shoe is connected with casing and its lower end is connected with the semilunar cement head. You can use the guide casing to lead it into the drilling hole. There is a back-pressure valve in the float shoe. You can use the oil well cement to fill the area between the float shoe and the body. The back-pressure can be cut by back-pressure valve. The upper hole and the lower hole will be open when the products after done . After the pressure of the circulating mud press the valve head into the lower place, the three collar valve on the valve tail will fall down automatically. The valve will press the valve seat tightly at the function of spring after the cement injection. And it will as a one-way valve function in the working. At that time, you could inject the mud into the pump from the upper end to the lower end, but the liquid of the well won`t be back in the casing below the valve or the outside circulation area of the casing.

Gate valves(ball screw operation) The ball-screw operation gate valve was developed for large-bore applications, to provide manual operation at full working pressure with remakably low opening torque.The design eliminates the need for gear-type torque multipliers, and results in quicker, safer operations. The ball-screw operation gate valve shares the basic features of the "ls"series:a slab gate, patented seat seal, non-elastomeric stem seals, and metal-to-metal sealing.However, the ball-screw operation gate valve has a lower balancing stem and unique ball screw mechanism Size:3-1/16", 4-1/16", 5-1/8", 7-1/16" Wp:10, 000psi, 15, 000psi Temperature:l u, pu Mat's:aa-ff psl:1-4 pr:1-2 Honorary certificate Our products have been iso9001 certified and attained api 6a, 6d, api 7, 7k, and api 16a&16c approvals of american pertroleum insitute.All products are fully designed and manufactured in accordance with api, ansi, gb(national standards)and sy(industry standards)standards.

2 " API safety relief valve 1) Safety valves are overpressure protection devices for protecting personnel and equipment, and usually installed in HP operation line for cementing/fracturing pumps, pressure vessels and other equipment under HP and high displacement. 2) The preset pressure value ranging 5000psi to 15000psi(35MPa to 105MPa) is adjusted through the top nut. When pumping pressure or operating pressure exceed the preset value, the safety valves will automatically open for pressure release. While the pressure is less than the preset value, they will be automatically closed. 3) The model of safety valve available: AQF02-105, AQF02-42,rated: 6000psi(42MPa)-15000psi(105MPa). Construction, connecting mode and size are same as SPM equivalent products; The butterfly spring inside can realize opening/closing of valves, therefore safety valves can protect people and equipment without shutting down relevant equipment. They are more reliable than shear type safety valves.
