One-Minute Overview

Centering Ring CS SWG: SS304.304L /FG, CS with the matched insulating set for ASME B16.20 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. Centering Ring CS SWG uses SS304.304L /FG, CS with the matched insulating set for ASME B16.20 flanges at 150LB. Qishine specifies it where a dependable dielectric break matters as much as leak tightness.

Name: Centering Ring CS SWG
Material: SS304.304L /FG, CS
Standard: ASME B16.20
Size: 6 Inch
Pressure: 150LB
Type: with inner and centering ring
Note: Full dimensions and bolt pattern are confirmed per inquiry.

Begin with the ASME B16.20 geometry and the 150LB rating, since they fix the gasket footprint and the bolt circle. Match SS304.304L /FG, CS 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 SS304.304L /FG, CS element seals the face while the matched insulating set 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 B16.20 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. How long will production take?

Standard sizes are typically ready within 30 days, and in-stock items ship immediately. Larger or custom orders get a confirmed date per order, because the schedule depends on quantity, material, the bolt pattern you specify, and how busy production is at the moment you order.
