Cheng Hsin Creation - Sealing Solutions for Petrochemical Industry
Chemical Resistant Extreme Material Applications
Selected high-specification perfluoroelastomer (FFKM) and special composite materials with excellent chemical compatibility, long-term resistance to corrosion by strong acids, alkalis and organic solvents, extending the life of seals to more than 2 times that of traditional materials.
Highly Reliable Damage Reduction Solution
Through precise material matching and structural optimization, it solves the problem of stress relaxation under high temperature and high pressure, and significantly reduces unplanned downtime, saving you hundreds of thousands of dollars per hour in downtime losses.
One-Stop Customization and Diagnostics
Our team of experts visit the site to diagnose the cause of seal failure and provide customized specifications and preventive maintenance recommendations that simplify spare parts inventory management and put maintenance budgets back under control.
Mechanical sealing system
Designed for critical equipment in the petrochemical industry such as pumps, mixers and compressors, it meets API 682 standards. They are available in temperatures from -100°C to 450°C and pressures up to 200 bar.
Double or tandem sealing structure with tungsten carbide, silicon carbide, special alloy and FFKM seals to effectively deal with highly corrosive and high-pressure fluids to achieve ultra-low leakage standards.
High Pressure Flange Gasket
Used for flange connections in pressure vessels, heat exchangers and piping systems, especially in high-temperature steam, acid-alkali, flammable and explosive chemical environments. Temperature range -200°C to 800°C, pressure up to 250 bar.
The main use of spiral wound gaskets (filled with expanded graphite or PTFE), metal toothed gaskets and corrugated gaskets provide excellent seal recovery and fire safety.
Elastomer O-Rings and Seals
Widely used on valves, pipe fittings and service holes to ensure the integrity of critical sealing points.
For extreme chemical media (e.g., strong acids, alkalis, ketones, aromatic hydrocarbons) and high temperature (up to 320°C) applications in petrochemical processes, we have selected high-performance materials such as perfluoroelastomer (FFKM), fluoroelastomer (FKM), and highly hydrogenated nitrile butadiene rubber (HNBR), which provide excellent chemical compatibility and long service life.
Valve stem packing system
Stem seals for gate, globe and control valves are designed to prevent leakage of volatile organic compounds (VOCs) and meet low leakage standards such as TA-Luft or ISO 15848-1.
Suitable for high temperatures (up to 600°C), high pressures (up to 400 bar) and highly corrosive environments. Reliable dynamic sealing solutions using expanded graphite rings, PTFE composite packings or aramid fiber braided packings.
An international oil company's Taiwan refinery was facing frequent leaks from crude oil pumps, with unscheduled downtime due to seal failures exceeding 72 hours per month, which was seriously affecting production efficiency.
After our detailed on-site evaluation and failure analysis, we found that the original seal design was not suitable for the high-temperature crude oil characteristics of the plant. We redesigned the sealing system by adopting a double-face mechanical seal configuration, selecting high-temperature resistant tungsten carbide material, and upgrading the cooling and flushing system.
Implement the results:
- Reduced seal failure rate 92%
- Extended MTBF from 3 months to 18 months
- Reduced annual maintenance costs by NT$6.8 million
- Reduced carbon emissions by about 150 tons of CO2 equivalent
