Core technological advantages, German precision craftsmanship strength

1. Multidimensional displacement compensationIntegrated axial, lateral, and angular triple compensation functions can efficiently absorb the displacement caused by pipeline thermal expansion and contraction, equipment operation vibration, and eliminate safety hazards such as pipeline cracking and medium leakage caused by stress concentration from the root, ensuring long-term stable operation of the pipeline system.

2. All media compatibility and adaptationThe NBR lining can withstand new media such as ethanol and biofuels, while the CR outer coating has strong weather resistance and ozone resistance. It is suitable for both traditional petroleum based products and new energy fuel transportation needs, greatly extending the service life of outdoor products.

3. Full dimensional security complianceBuilt in power dissipation structure, with resistance controlled within the range of 1k Ω~1M Ω, effectively avoiding safety risks caused by static electricity accumulation; The rotatable flange design enables quick installation at any angle, and the product fully complies with strict industry standards such as DNV-GL and classification societies, meeting safety requirements in the fields of ships and oil and gas.

4. Whole process quality controlStrictly following German precision manufacturing standards, each product undergoes dual testing of pressure and fatigue before leaving the factory to ensure stable pressure and zero leakage sealing, reducing maintenance costs and production downtime losses from the source.

Scientific selection guide for precise matching of needs

Core principles of selection

1. Matching of working condition mediaConventional petroleum based products, fuels, and gas transportation are selected using the basic SERV-G series; For low-temperature scenarios in cold regions, priority should be given to the SERV-G LT model; For scenarios with fire prevention requirements, choose the SERV-GS model; Suitable for high temperature, high humidity, and frequent equipment start-up and shutdown conditions, with the RV-GS HNBR model.

2. Temperature and pressure parameter matchingStrictly compare the parameters of each model, match the actual medium temperature and working pressure, and ensure that the short-term operating temperature of the medium does not exceed+100 ℃ to avoid material aging and performance degradation caused by overheating.

3. Flange material matchingThe basic model comes standard with DIN PN10/16 carbon steel flanges, which can be customized with stainless steel or aluminum alloy flanges according to the pipeline material and the corrosiveness of the conveying medium to ensure the sealing and compatibility of pipeline connections.
