C-type ultra-high pressure and extra-large clearance sealing element is composed of sealing ring, sector supporting block and supporting Angle. It is mainly used for the pressure test of steel tube by water pressure testing machine. Type C sealing element has larger sealing clearance than type D (see our company’s previous sample for details), and the sealing ring of the same specification can be applied to a wider range of steel pipe specifications. This product is suitable for water pressure test of casing pipe, oil pipe, natural gas conveying pipe, etc.
NM type internal expansion sealing element is composed of sealing ring, sector supporting block and supporting Angle. It is mainly used for the pressure test of steel tube by water pressure testing machine. As the NM type internal expansion sealing element seals the steel tube from the inner diameter, the sealing ring expands outward to contact with the inner wall of the tube and seals during the pressure test, so its pressure test head is smaller than that of type D or type C, and the manufacturing cost is low. This product is suitable for hydraulic test of casing pipe, oil pipe, natural gas pipe and so on.
PYG skeleton type plane sealing element is a y-shaped plane sealing ring, specially designed for plane sealing of water filling test head and exhaust test head of steel tube hydraulic testing machine. During installation, the two planes should be in close contact, and pay attention to the installation direction of the sealing ring.
Y-type skeleton seal ring is composed of a y-type seal ring with a section and a reinforced PTFE gasket, which is used in the water-filling mold and exhaust mold of the water pressure testing machine for steel tubes. Its function is the same as the rectangular slip-ring combined seal ring in the design of conventional hydraulic press. The processing of sealing groove and the installation of sealing ring are simpler and more convenient than the rectangular slip-ring combined seal ring.
The utility model relates to an elastic rubber seal ring with axial action, which is used as a non-pressure seal for a rotating shaft. The sealing lip has the better activity and the adaptability, may compensate the big tolerance and the Angle deviation, may prevent the internal grease or the oil liquid leakage outward, also may prevent the outside splashing water or the dust invasion.
Mainly used for static seal and reciprocating motion seal. For rotary motion seals, limited to low speed rotary seals.
Widely used in reciprocating dynamic sealing device.
In addition, there is spring tension (spring energy storage) seal ring, is added in PTFE sealing material a spring, O spring, V spring, U spring.
