One-Minute Overview

Klingersil C4430 Sheet Gasket: Klingersil C4430 with G10 sleeves, washers and ZPS for ASME B16.5 flanges.
Specified for 6 Inch and 150LB service, it seals the joint and holds the dielectric separation.
The insulating sleeve stack keeps every bolt from touching the flange metal.
Bore, thickness and bolt circle are confirmed per inquiry.

A flange isolation assembly performs two functions in one joint: it seals the face and interrupts the metallic path that carries stray currents between pipe sections. Klingersil C4430 Sheet Gasket uses Klingersil C4430 with G10 sleeves, washers and ZPS for ASME B16.5 flanges at 150LB. Qishine specifies it where a dependable dielectric break matters as much as leak tightness.

Name: Klingersil C4430 Sheet Gasket
Material: Klingersil C4430
Compound: aramid fibre with a nitrile binder
Standard: ASME B16.5
Size: 6 Inch
Pressure: 150LB
Complete with: G10 sleeves and washers with ZPS
Note: Full dimensions and bolt pattern are confirmed per inquiry.

Begin with the ASME B16.5 geometry and the 150LB rating, since they fix the gasket footprint and the bolt circle. Match Klingersil C4430 to the process medium and confirm that the 6 Inch bore clears the pipe ID; the insulating stack must retain its dielectric strength under full bolt load.

Clean both flange faces, centre the gasket on the bore and bring the bolts up in a star pattern so compression stays even. Sleeves must cover the full grip length and seat square under the washers; a short or cocked sleeve can crush and short the bolt to the flange. Recheck torque after the first heat-up, then verify that protection current stays on the intended side of the joint.

FAQ

Q1. How does the kit stop current crossing the flange?

The Klingersil C4430 element seals the face while G10 sleeves and washers with ZPS isolate each bolt from the flange metal. With the metallic path broken, cathodic protection current remains on the protected side and galvanic corrosion between dissimilar metals is held in check.

Q2. What should be inspected on the flange face before fitting?

Check the ASME B16.5 faces for pitting, warping and old gasket debris, then verify the bore clears the pipe. A flat, clean face lets the element compress evenly; a scored face concentrates bolt load and invites a leak at 150LB.

Q3. Does the insulating sleeve change the tightening procedure?

Tighten in a cross pattern in several passes to the torque set by the flange and bolt grade. Sleeves and washers must seat square, so confirm the full stack-up and recheck torque after the first thermal cycle.

Q4. What's the minimum I can order?

Standard flange insulation gasket kits start at one set, and standard gaskets, studs, washers and sleeves start at one piece. Kits made to your drawing or for a non-standard bolt pattern are quoted individually, because the minimum really depends on the material and the tooling involved.
