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.
Chain plate mesh belt The chain plate belt is very strong, driven by the stainless steel chain, stainless steel plate production, suitable for high density transportation in small, in the conveying process of stable operation, convenient installation and replacement, long service life. For medium and heavy load transportation. Steel plate bending forming hinge, pivot hinge and the chain will use both ends together. The chain can be used to fix the washer or cotter pin, cotter pin use convenient disassembly, convenient maintenance. The chain plate roughly divided: 1, according to the material: steel chain plate conveyor belt, galvanized plate chain conveyor belt, 201 stainless steel chain plate conveyor belt, 304 stainless steel chain plate conveyor and other stainless steel chain plate conveyor based on.2 shape: flat plate chain conveyor belt, with transverse baffle plate chain conveyor belt, with a side chain plate conveyor, chain plate conveyor belt (punching hole, long hole), with a convex chain plate conveyor belt.3, according to the form of transportation: direct transmission chain plate conveyor belt, turning chain plate conveyor belt. 4, the hinge chain plate conveyor belt, chip conveyor chain plate conveyor belt, steel chain plate conveyer belt. 5, double pitch chain chain plate belt, precision roller chain and chain plate conveyor belt.
