PHE Gaskets: Reliable Sealing for Plate Heat Exchangers
Plate Heat Exchangers (PHEs) rely heavily on high-performance gaskets to keep fluids separated, maintain pressure stability, and ensure heat transfer efficiency. At Xiamen Jinshun Sealing Technology Co., Ltd., we design and manufacture custom PHE gaskets engineered for long service life, high temperatures, aggressive chemicals, and demanding industrial environments.
Whether your application involves chilled water, steam, corrosive fluids, food processing, or petrochemical media, we provide precisely molded PHE gaskets that enhance heat exchanger reliability and lower maintenance costs.
Why Choose Our PHE Gaskets?
1. High-Temperature Resistance
Our gasket materials handle a broad temperature range, from -200°C up to 260°C, depending on the selected polymer.
2. Chemical Compatibility for Diverse Media
We supply NBR, EPDM, FKM, PTFE, HNBR, silicone, and customized compounds formulated for acids, alkalis, oils, and coolants.
3. Proven Durability
Most PHE gaskets offer a service life of 2–5 years, depending on operating conditions.
4. Full OEM/ODM Support
We reverse-engineer gaskets from samples, drawings, or damaged parts. Large-scale production for global brands is available.
5. Competitive Factory Pricing
Direct manufacturing in Xiamen reduces lead times and produces cost-effective sealing solutions for international distributors.
Types of Heat Exchanger Gaskets We Produce
We manufacture gasket solutions for plate-type, tube-type, and shell-and-tube heat exchangers, including:
1. Soft Gaskets (Non-Asbestos / NBR / EPDM / FKM)
Soft gaskets made from materials such as NA1081 (Kevlar + NBR) deliver excellent sealing performance for steam, oils, water, hydrocarbons, and mild chemicals.
2. Jacketed Gaskets
A metal-jacketed outer shell with a softer filler core. Ideal for high-temperature or large-diameter flanges and heat exchangers in power plants and steel mills.
3. Corrugated Core Gaskets
Our corrugated gaskets combine flexible graphite and a corrugated stainless-steel core, delivering a strong seal under low bolt loads and maintaining performance through thermal cycling.
Material Options & Properties for PHE Gaskets
Below is a comparison table to help you select the right material for your application:
Material Performance Table
| Material | Chemical Resistance | Common Media | Temperature Range |
|---|---|---|---|
| NBR | Fair (avoid strong oxidizers) | Water, mineral oils, air | -30°C ~ 120°C |
| EPDM | Excellent for water/steam (avoid oils) | Hot water, steam, refrigerants | -40°C ~ 150°C |
| FKM / Viton | Outstanding resistance to oils & solvents | Oils, fuels, acids/bases | -20°C ~ 200°C |
| PTFE | Near-inert, best chemical resistance | Strong acids, bases, solvents | -200°C ~ 260°C |
| HNBR | Superior oil & high-pressure performance | Hydraulic oil | -30°C ~ 160°C |
| Silicone (VMQ) | Excellent low-temperature flexibility | Ultra-low-temperature media | -50°C ~ 200°C |
Recommended Material Based on Working Medium
| Medium | Recommended Rubber | Service Life | Cost Level |
|---|---|---|---|
| Water / Steam (≤120°C) | EPDM | 3–5 years | ⭐⭐ |
