Use a complete dimension set
Provide outside diameter, bore, thickness, bolt-hole count, hole diameter and bolt-circle diameter. Include matching pipe outside diameter and required tolerances.
LEKE PIPING / PRODUCTS
Plate flanges are flat ring-type flanges. Specify the standard or drawing, bore, thickness, facing and bolt pattern.

PRODUCT DETAILS
We can also make custom sizes, thicknesses and other dimensions to your drawing. Send your specifications with your RFQ so we can confirm the details.
| Parameter | Details to confirm |
|---|---|
| Geometry | Flat ring construction |
| Dimensions | Outside diameter, bore, thickness, bolt-hole count, hole diameter and bolt-circle diameter |
| Reference | Standard and edition, flange type and pressure designation, or approved drawing revision |
| Material | Material specification, grade and required material certificates |
Product dimensions, material grades and documentation are confirmed against your enquiry and applicable project requirements.
Primary dimensional reference: The specified plate-flange standard or approved drawing. Confirm the product type, edition and applicable size before order.
SELECTION & ENQUIRY
Provide outside diameter, bore, thickness, bolt-hole count, hole diameter and bolt-circle diameter. Include matching pipe outside diameter and required tolerances.
Provide the standard and edition, flange type and pressure designation, or the approved drawing revision. Confirm the facing and dimensions of the mating connection.
Mark non-standard dimensions, machining tolerances and facing finish on the drawing. Include inspection criteria for review before manufacture.
TECHNICAL REFERENCES
Plate-flange standard / approved drawing
Use the specified plate-flange standard or approved drawing. Check the flange type, size, pressure designation, material and facing against its scope before ordering.

COMMON QUESTIONS
Send the complete dimensional drawing, material and quantity for a manufacturing review.
No. Thickness alone does not establish the required specification or allowable service. Provide the governing design documents, material and complete dimensions.
Identify the required face geometry and finish from the approved drawing or specification. Include mating connection requirements where they affect the review; do not leave the facing to be inferred from a photo.
Include the outside diameter, bore, thickness, bolt-hole diameter and bolt-circle dimensions, as well as facing details and the mating flange information.
Specify the actual material designation and required documentation rather than using a generic description such as steel. Confirm manufacturing and supply scope with the enquiry.
