Peak Pressure and Blow Out

Leak rate on internal pressure applied.
According to Global oil major’s type acceptance test, this test verifies sta-
ble sealing performance without leakage and breakage when internal pres- sure increases beyond 60 bar with minimum gasket seating stress main- tained. This test shall meet related industries requirement

Steam Service

Based on excellent gas permeability, it provides stable sealability in steam applications compared with conventional CNAF. Normally drastic change of thermal or pressure cycling is highly effected on sealability, but high dense inner structure of Eco Friendly Gasket Sheet enhances longer and lower life cycle cost for customers.

Durability

Actual field test performed at a chemical plant to confirm excellent durability above specified condition and leakage has not detected at steam line for 1,000 days.

Insulation Properties

In accordance with authorized institute, Eco Friendly Gasket Sheet demonstrates out- standing results in electrical isolation performance. Compare to testing result against conventional CNAF and reinforced PTFE materials, Eco Friendly Gasket Sheet has the highest level of electrical isolation performance in ambient and water dipping condition.

Stress Relief

With superior heat resistance of Eco Friendly Gasket Sheet, above test result demonstrates excellent sealability in critical conditions (high temperature & pressure but reducing seating stress). This strength has shown stable seal- ing advantage on relief bolting stress at high temperature condition.

Low Seating Stress

With special UMCS*, Eco Friendly Gasket Sheet shows outstanding stability at low seating stress where achieving standard torque is not possible in ac- tual assembling construction fields.

Deformation

Simultaneously applied condition of high seating stress 120MPa and 200°C, Eco
Friendly Gasket Sheet has strong physical properties and less deformation while test- ing verification of gasket thickness, surface change and breakage.

Removability

Eco Friendly Gasket Sheet has designed to considering low maintenance costs. Per-formance testing under the condition of 120MPa and 200°C. Eco Friendly Gasket
Sheet has shown excellent and easy removability with no adhesion on the flange sur- faces. This contributes to cost saving and flange protection.

Productivity

Specially designed by UMCS* process contributes to re-markable improvement in high productivity and excellent die-cutting ability as against conventional CNAF*.
