Beijing Jianke Huifeng Technology Co., Ltd. is a technology-based manufacturing enterprise specializing in the research, production, and sales of sealing rings, sealing components, combined sealing rings, ultra-high pressure sealing rings, V-shaped sealing rings, foot-shaped sealing components, NM internal expansion sealing components, imported sealing components, ultra-high pressure sealing components, and other products.

1. The C-type ultra-high pressure large gap sealing element consists of a sealing ring, a fan-shaped support block, and a support angle. It is mainly used for pressure testing of steel pipes in hydraulic testing machines. The C-type sealing element has a larger sealing gap than the D-type (see previous samples from our company), allowing a wider range of steel pipe specifications to be applicable with the same specification sealing ring. This product is suitable for hydraulic testing of casing, oil pipes, natural gas transportation, and other steel pipes, and can also be used for leak detection of steel pipes, pipe joints, welds, and ultra-high pressure valve sealing.

2. The NM-type internal expansion sealing element consists of a sealing ring, a fan-shaped support block, and a support angle. It is mainly used for pressure testing of steel pipes in hydraulic testing machines. Since the NM-type internal expansion sealing element seals the steel pipe from the inner diameter, during pressure testing, the sealing ring expands outward to contact and seal the inner wall of the pipe, making its pressure testing head smaller and more cost-effective than the D-type or C-type. This product is suitable for hydraulic testing of casing, oil pipes, natural gas transportation, and other steel pipes.

3. The PYG-type skeleton flat sealing element is a flat sealing ring with a Y-shaped cross-section, specifically designed for the flat sealing of water filling pressure testing heads and exhaust pressure testing heads in steel pipe hydraulic testing machines. It requires tight contact between the two flat surfaces during installation, and attention should be paid to the installation direction of the sealing ring.

4. The Y-type skeleton sealing ring consists of a Y-shaped sealing ring and a reinforced polytetrafluoroethylene (PTFE) gasket, used in the water filling molds and exhaust molds of steel pipe hydraulic testing machines. Its function is the same as that of the conventional right-angle sliding ring combination sealing ring in hydraulic machine design, and the processing of sealing grooves and installation of sealing rings are simpler and more convenient than the right-angle sliding ring combination sealing.

 

V-type sealing ring

is an axially acting elastic rubber sealing ring used for non-pressure sealing of rotating shafts. The sealing lip has good mobility and adaptability, compensating for larger tolerances and angular deviations, preventing internal grease or oil from leaking out, and also preventing external splashes or dust from entering.

 

O-type sealing ring

is mainly used for static sealing and reciprocating motion sealing. When used for rotating motion sealing, it is limited to low-speed rotating sealing devices.

 

Y-type sealing ring

is widely used in reciprocating sealing devices.

Additionally, there are spring tension (spring energy storage) sealing rings, which incorporate a spring into the PTFE sealing material, including O-type springs, V-type springs, and U-type springs.

Beijing Jianke Huifeng Technology Co., Ltd. is a technology-based manufacturing enterprise specializing in the research, production, and sales of sealing rings, sealing elements, combination sealing rings, ultra-high pressure sealing rings, V-type sealing rings, foot-type sealing elements, NM internal expansion sealing elements, imported sealing elements, ultra-high pressure sealing elements, and other products. The company has established cooperative relationships with more than ten well-known hydraulic testing machine design units in China, providing matching design and production of various new sealing products. The company's products have won two national patents and have passed the ISO9001:2000 national quality management system certification.
