VCS Very Critical Service Flange Insulation Gasket Kit

What is VCS Very Critical Service Flange Insulation Gasket Kit?

The FIK 600-VCS VCS very critical service flange insulation gasket kit is a significant reliability gasket used for both insulation and typical sealing uses in Very Critical Services. The central big gasket is made of Insulation materials such as G10 with Metallic SS316L core. It has a proven reputation of dependability in aggressive sealing situations. The VCS very critical service flange insulation gasket kit is suitable in all services as much as and as well as ANSI 2500# and API 15,000 PSI. The VCS High Pressure Flange insulation Gasket Kit is ideal for service where the cost of gasket malfunction can not be accepted.

VCS very critical service flange insulation gasket kit delivers the greatest safety and consistency in the most challenging, hazardous conditions on the planet. By using the high quality materials and professional design for sealing, our critical service falnge insulation gasket kits give you with the dependability you need when failing is completely unacceptable.

One key point about the VCS very critical service flange insulation gasket kit not like other types only used for raised flange or full face flange, the gasket can be used for raised Flange, full face flange and ring type joint flange. The gasket we make can be used for all ANSI, ASME B16.5, and AWWA size.

Components of VCS Very Critical Service Flange Insulation Gasket Kit

Central Big Gasket Retainer

The big gasket retainer is usually a G10 gasket bonded with SS316 metal core, and sometimes the metal core can be SS304 or super duplex S31803. Because of its exclusive pressure triggered sealing system, the gasket demands far less bolt stress to seal than other gasket. The VCS insulation gasket inner diameter is just coordinated to the flange bore to remove turbulent flow and flange face corrosion. The seal components are generally replaceable in the reusable gasket retainer.

PTFE (Teflon) Spring Energized Seal

The VCS very critical service flange insulation gasket kit includes a PTFE (Teflon) spring energized seal, or perhaps rubber elastomeric o-ring, seated in an insulating laminate of the big central gasket retianer and which is certainly permanently bonded to the high strength big central gasket.

Isolation Washers

The isolation washer materials can be G10, G11, Mylar, Nomex, Mica or other materials.

Metallic Washers

The metallic washers of VCS flange insulation gasket kit can be zinc plated carbon steel washer, XPS, HCS and Stainless steel such as SS 316, SS 304

Isolation Sleeves

The Isolation washers of VCS flange insulation gasket kit can be Mylar, G10, G11, G7, Mica

Applications of VCS Very Critical Service Flange Insulation Gasket Kit

VCS very critical service flange insulation gasket kit can be used for cathodic protection, Insulation between dissimilar metals to prevent galvanic erosion, wellhead isolation from inter-connected flow lines. And as its excellent sealing results, it can be used to seal and isolate valve associations, Christmas Tree connections, Pump connections, Compressor connections, Tanks and heat exchangers with sacrificial anodes to increase anode life. It can Mate mismatched ring joint to raised face flanges. Remove fluid trap corrosion between RTJ flanges where high concentrations of CO2, H2S, other extreme hydrocarbon media exist and turbulence and flow-induced erosion between ring-joint (RTJ) flanges.

Why We Use VCS Very Critical Service Flange Insulation Gasket Kit?

The reason for why we use vcs very critical service flange insulation gasket kit is as it has many benefits and advantages. It has very high dependability sealing and also insulation for all critical services, it may seal and also insulate at all pressures up through ANSI 2500# and API 15,000 psi. It could bear severe service problems, which include large bending moments, vibrations, temp, along with pressure cycling, additionally, it can withstands corrosive environments, including large concentrations of CO2, H2S, outlet water, and many more. It owns outstanding isolating properties for cathodic security, galvanic corrosion, and various other pipe system isolation requirements. Stress activated for dependable sealing and reducing costly leakages.

The gasket is exactly sized to your bore to secure flange encounters as well as reduces turbulent flow at flanged associations to minimize media-induced corrosion and also flow-induced erosion. It could reduces microbially induced erosion in addition to obtunds galvanic corrosion in dissimilar metal flanges. Its sleeves and also washers always consist of high strength double washers and full-length sleeves for maximum certainty against brief circuits. The Spring energized PTFE seal gives radial load and encapsulation in the seal groove to eliminate cold flow. It can be used to match any flange specifications (ANSI, API, BS, DIN, AS, others)

It is easy to set up, make up in addition to remove the rigid construction helps facilitate installment. And it just requires small necessary bolt loads, much less makeup pressure is required resulting in less flange and bolt stress. It is Self-aligning and centering gasket kits and no unique tools necessary when install.
