Description

Leinseal® Sealing gasket is a designed for electrical flange insulation in general application. It is suitable for raised face or flat face flanges up to class ANSI 1500#. Leinseal is available in both type F (ring type) and type E (full face), with kits, it is excellent for general applications where electrical flange insulation and corrosio n control are required.

Leinseal® gasket consist of a retainer with two special designed seal grooves on both sides and sit with two rectangular elastomeric sealing elements (Quad ring), this design guarantees the high sealing reliable under the low bolt load.

Applications:

Low pressure : up to 1500# for raised face and flat face flanges
Most of water, gas, oil and hydrocarbon service
H2S /Co2 service
High pH service
Low bolt load required service

Advantages and Benefits

Extreme high-reliability sealing and insulating solution for low pressure services
Seals and insulates at low pressures classed up to ANSI1500# service
Designed to withstand corrosive environments, including high concentrations of CO2 , H2S, produced water, etc.
Outstanding insulation properties for cathodic protection
Pressure-activated seals provide high confidence sealing and eliminate costly leaks
Gasket is sized to the bore to protect flange faces from media-induced corrosion and flow induced erosion
Prevents turbulent flow at flanged connections
Mitigates galvanic corrosion in dissimilar metal flanges
Available to match any flange specification (ANSI,API,MSSP,BS,DIN,AS,others)
Easy installation, make up and removal
