DESCRIPTION OF PRODUCTS
Metal spiral wound gasket is widely used as a sealing gasket at present.
It is the best elastic gasket in semi-metal sealing gasket. It is made of V-shaped or W-shaped thin steel belt and various fillers alternately wound and can withstand The use of high temperature, high pressure and conditions suitable for ultra-low temperature or vacuum conditions can solve the problem of chemical corrosion of various gaskets by changing the material combination of the gasket.
The structural density can be made according to the different locking force requirements to strengthen The main body and accurate positioning, winding gasket with metal inner ring and outer ring, using internal and external steel ring to control the maximum compression, the gasket surface contact surface of the flange sealing surface requirements are not high.
APPLICATION
* Suitable for uneven load, easy relaxation of joint force, periodic change of temperature and pressure, impact or vibration.
* Is the valve, pump, heat exchanger, tower, manhole, hand hole and other flange connections of the static seal original,
* Widely used in petrochemical, machinery, power, metallurgy, shipbuilding, medicine, atomic energy and aerospace and other departments.

CHARECTERISTIC
1.The applicable working condition range is wide. Can resist high temperature, high pressure, and adapt to the use condition of ultra-low temperature or vacuum. By changing the material combination of the gasket, the chemical corrosion problem of the various media to the gasket can be solved.
2.The stress compensation ability is strong. The sealing performance is stable and reliable at the station with frequent temperature and pressure fluctuation.
3.The sealing performance is excellent.
4.The surface accuracy requirement for flange sealing contact with the gasket is not high. 5.The installation is convenient, and the pre-tightening pressure of the gasket is low.
Chunhuan Group (Zhenjiang Chunhuan Sealing Group Co., Ltd.), established in 1985, is a leading manufacturer of fluoroplastic products, chemical semiconductor linings, and new energy sealing gaskets. The company primarily focuses on the research, development, and production of fluoroplastic series sealing products (for hydrogen energy and nuclear power applications) and chemical semiconductor linings. With subsidiaries in South Korea and Shanghai, the group has also established a joint venture with South Korea's Houcheng Group for semiconductor lining equipment. Main production: PTFE products, metal seals series, steel lining anti-corrosion series, engineering plastics series,rubber products series,it is the leading enterprise in the national fluoroplastics industry. The company supplies more than 300 varieties of PTFE composite modified materials,ranging from standard composite modified materials (bronze,glass fiber,carbon,graphite,etc.) to customized solutions to meet different production needs of customers.The company provides flexible quantity and fast delivery service. The engineers have 35 years working experience in the field of PTFE,serving customers in more than 30 countries.
1. Q: What engineering plastic materials do you mainly produce?
A: We specialize in high-performance engineering plastic products such as PTFE (Polytetrafluoroethylene), PEEK (Polyetheretherketone), Nylon, and UHMW-PE (Ultra-High Molecular Weight Polyethylene).
2. Q: What are the key advantages of PTFE material?
A: PTFE offers excellent chemical resistance, high and low temperature stability (-200°C to +260°C), an extremely low friction coefficient, and outstanding insulation properties.
3. Q: Can you provide customized sealing components?
A: Yes, we support customization of seals (e.g., O-rings, gaskets, sealing rings) in various shapes, sizes, and materials based on customer drawings or technical requirements.
