The processing technology of turning seals is different from that of traditional molded seals. The raw materials for turning hydraulic seals are blank barrels formed by high-pressure extrusion of raw materials after heating and melting, and then the hydraulic seals are turned by special turning CNC seal processing equipment that programs various seal data through software. Turning hydraulic seals ...

In oil production, fracturing technology is one of the important measures to improve oil production and reserves. In order to achieve the purpose of increasing production, every oil well in the oilfield needs to be fractured, and some oil wells even need to be fractured many times. Generally, 4-5 fracturing trucks operate in the downhole oil layer to form a fracture, and the oil flows to the fract...

The T-seal is developed to replace the existing O-ring in the long-life hydraulic and pneumatic system, because the O-ring rolls in the sealing groove, which is easy to cause screw failure. Their ability to fit into existing grooves means they can be retrofitted without rework or major modifications to existing hardware designs, simplifying field changes and new equipment manufacturing. The T-seal...
