Float Collar is run in a casing assembly, usually several joints above the Float Shoe. It serves as an extra back pressure valve sealing against pressures from blow while running the assembly and after the cementing job. Internal latch and valve are readily drillable. Its capability of back-pressure is over 25MPa.
Float Collar, the float shoe also has aback-pressure valve to prevent back flow. It permits cement to run through side ports when the nose of the shoe is on the bottom. Inner valve and bottom guides are all made of drillable material. Its capability of back-pressure is over 25MPa.
The Float Collar and Float Shoe is 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.
Ultra clear float glass also called low iron float glass, is produced by less amount of iron in the molten glass formula(usually from 90-110ppm). This type is more transparent than regular glass and it doesn\'t have that greenish tint. The less iron content can increase the light transparency. ultra clear glass is the best choice for architects and designers when need color-matching.

JHG tinted glass is produced by metal oxides to the float glass. The colour may be transferred in the series of blue, green, grey, bronze flexibly. The performance of visible light, privacy and solar heat transmission will be changed arrording the colour change. Different tinted glass offers varied application possibility-from interior partitions, to home appliance, to furniture, to facades and auto field. Reflective glass is float glass with a metallic coating that cuts off solar heat.The coating film may provide mirror effect, preventing visibility from outside and preserving privacy. JHG mainly offer 2 kinds of reflective glass. Hard reflective glass (on line) includes blue, green, grey, bronze, pink, silver colour, Soft reflective glass (off line) includes golden, silver, purple colur.

Float glass is the standard clear glass that is widely used in buildings. It is produced by floating molten glass on a bed of molten metal, resulting in a smooth and uniform surface. Float glass is transparent and allows ample natural light to enter indoor spaces, making it a popular choice for windows and glass facades. Its clarity and simplicity complement various architectural styles

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.
