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.
V 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.
O ring seal
Mainly used for static seal and reciprocating motion seal. For rotary motion seals, limited to low speed rotary seals.
Y ring seal
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.

In the realm of water supply systems, the choice between materials can significantly impact the efficiency, durability, and overall performance of the infrastructure. This article delves into the comparative analysis of PE (Polyethylene) and PVC (Polyvinyl Chloride) water supply pipes, elucidating the distinctive features that set them apart.
Silicone duckbill valves, often referred to as one-way check valves or non-return valves, which are designed to allow the flow of fluids in one direction while preventing backflow. Their unique construction consists of a flexible, elastomeric material – typically silicone – shaped like a duck's bill.
Unlocking the Strength: Understanding the Pressure Tolerance of Ductile Iron Pipe In the realm of modern engineering and infrastructure, the strength and durability of materials are paramount. One such material that has been the backbone of water and sewage systems for decades is ductile iron pipe. But have you ever wondered, "How much pressure can ductile iron pipe hold?" In this comprehensive guide, we will delve deep into the world of ductile iron pipes, exploring their pressure tolerance, applications, and the factors that influence their performance.
Plastic pollution and environmental concerns have led to a growing emphasis on sustainability and recycling within the beverage and packaging industry. One promising innovation in this realm is the use of rPET (recycled polyethylene terephthalate) bottles.
In the world of engineering and machinery, high-pressure seals play a pivotal role in ensuring the efficient and safe operation of various systems. These seals are responsible for containing fluids or gases under intense pressure, preventing leaks, and maintaining the integrity of the equipment. The choice of material for high-pressure seals is crucial,
