The procurement problem

Check fit and access before ordering

Twenty flanges in nineteen emails

A maintenance list usually mixes sizes, faces and locations. When each item arrives separately, the unit system, the tags and the drawing revision drift apart.

Bolt access is a design question

Whether the gasket area and bolts must remain inspectable changes the structure. We record that requirement per item rather than assuming it applies to the whole schedule.

Clearance decides removability

Available axial and radial space around a flange pair is often the limiting factor. A schedule that captures clearance is far more useful than a list of nominal sizes alone.

Fit and service access

Prepare your equipment details

Build one item schedule

One row per flange or flange pair with a tag, nominal size and face type, quantity by size, available clearance, location and a note of any inspection point that must stay visible.

Add evidence in phases

Start with the schedule. Attach drawings or scaled photos as they become available, and keep the revision identifier on each file.

Specify how the cover comes off

Mark the space needed for bolt work and where the closure can be reached. Include adjacent insulation dimensions and the required direction of removal.

RFQ STEP 3

Attach the drawing or photos

PDF, JPG or PNG, up to 5 files and 10 MB each. If you do not have a final drawing, a short description and one photo with a scale reference are enough to start.

Steam trap caveat: If your project includes steam traps, whether a trap should be insulated depends on the trap type and the manufacturer’s guidance. We do not recommend covering all trap types.

MULTI-ITEM PROJECTS

Landing page FAQ

Questions buyers ask before submitting.

Can one RFQ cover different flange sizes?

Yes. A consolidated item schedule is the preferred format. Use one unit system, a tag per line and a quantity by size.

Must every drawing be attached at the first step?

No. The first inquiry only needs an email address, a product direction and a short requirement or one attachment. Further technical detail can be added later.

Do you publish prices or a minimum order quantity?

No. Both are subject to quotation and technical review. No MOQ or price exists on this site.

Do you promise a quotation turnaround time?

Timing depends on fit, materials, quantity and supplier confirmation. Include your shutdown or required dispatch date so it can be reviewed with the specification.

Are the gallery illustrations real products?

No. They are original concept illustrations labelled as such, not photographs, samples or stocked items.
