Slip-On Flanges

Product overview

Hua Chuang supplies slip-on flanges for industrial pipe connections. Compare the specified flange type with the project drawing before requesting a quotation; slip-on and weld neck flanges should not be substituted solely because their nominal size is the same.

Purchase specification For a slip-on flange quotation, state the standard and edition, DN or NPS, PN or Class, facing, material grade and mating pipe outside diameter. Supply a drawing where bore, hub or installation dimensions are controlled by the project. Ask the project engineer to confirm the connection and installation requirements.

Inspection, documents and packing State the required material documents, inspection scope, marking and packing in your RFQ. These items, any proposed alternatives and the delivery schedule should be confirmed in the written quotation and order. Do not assume optional tests or documents are included.

Preparing your enquiry Send an itemized quantity, destination country or port, requested delivery date and the drawing or bill of materials if available. For mixed orders, give each line its own specification so products and quantities remain traceable.

Frequently asked question What should I send when replacing an existing slip-on flange? Send the original specification or drawing, visible markings and measured mating dimensions. A photograph helps identify the item, but does not replace the material and dimensional requirements.

Specify the mating flange, nominal size, drilling pattern and facing together. A matching nominal size alone does not establish interchangeability between different flange standards. For weld neck flanges, include the pipe bore and wall thickness; for threaded designs, identify the thread standard. Select the gasket and bolting as part of the complete joint.

Technical specifications

Confirm the material grade, dimensions, pressure class and standard together against the approved drawing before ordering. Schedule denotes wall thickness, not a pressure rating.
