One-Minute Overview

1 Inch G10 Insulation Gasket is built for a leak-tight ANSI B16.5 face at 150# with a G10+PTFE sealing element.
the matched insulating set come as a matched set, so the insulating stack stays concentric under bolt load.
The 1 Inch bore and gasket OD are checked against the flange drawing before cutting.
Final thickness and bolt circle are confirmed per inquiry.

Leak tightness on an isolated flange depends on even compression, not just on the gasket material. 1 Inch G10 Insulation Gasket combines a G10+PTFE element with the matched insulating set for ANSI B16.5 flanges rated 150#. The assembly is sized for 1 Inch so the sealing face and the insulating hardware work as one stack.

Name: 1 Inch G10 Insulation Gasket
Material: G10+PTFE
Standard: ANSI B16.5
Size: 1 Inch
Pressure: 150#
Brand: Qishine
Usage: B16.5 flange
Note: Full dimensions and bolt pattern are confirmed per inquiry.

Confirm the facing type, the 150# class and the ANSI B16.5 bolt circle first, because they determine how much compressive area is available. Then check that the G10+PTFE element suits the medium and that the 1 Inch bore leaves the pipe clear; an undersized bore creates turbulence and erodes the gasket edge.

Degrease both faces and remove all old gasket material before setting the element concentric with the bore. Bring bolts up in three cross-pattern passes, pausing between passes so the G10+PTFE element creeps evenly. Fit sleeves square under the washers, then recheck torque after the first thermal cycle when gasket relaxation is greatest.

FAQ

Q1. What causes an isolated flange to leak after start-up?

Uneven bolt load, a damaged ANSI B16.5 face or a sleeve seated at an angle are the usual causes. Creep of the G10+PTFE element after the first heat-up also relaxes the joint, which is why a torque recheck is specified.

Q2. How is the 1 Inch bore verified before the gasket is cut?

Compare the pipe ID and the ANSI B16.5 flange drawing with the proposed bore. The opening must clear the pipe without leaving an unsupported gasket ring that could extrude at 150#.

Q3. Why must the whole insulating stack come from one kit?

Mixing the matched insulating set from different sources changes stack height and compression. A matched set keeps every bolt equally isolated and lets the G10+PTFE element compress uniformly across the face.

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.
