This JIS B2220 polished bolted hub flange enquiry starts with the hub and its connection to the pipe. Select the required component profile and accepted material package before matching the mating flange. A hub-shaped photograph alone cannot establish the supplied flange type or rating.

Define the hub profile and pipe attachment

Provide a drawing showing the hub height, bore, neck-to-body geometry, flange thickness and outside diameter. Specify the intended pipe attachment and any preparation needed for that connection. Do not select a welding, socket, slip-on or threaded arrangement from a generic hub-flange name alone.

Identify any NPT or BSPT feature by the actual threaded component and end specification. The bolted mating joint should have its own facing, gasket contact geometry, bolt circle, hole count, hole diameters and tolerances. Repeated inch ranges cannot replace the complete interface drawing.

Select material, nominal size and JIS scope

Polypropylene and PP choices require confirmation of the supplied material designation and any separate backing or support parts. Request product condition and inspection traceability for the accepted configuration. Size None is not a nominal-size selection, so state the required size explicitly in the enquiry.

Agree the applicable JIS B2220 edition, flange type, material and rating designation. Class 150 wording does not establish a JIS equivalence. Set the accepted pressure-temperature basis for the delivered assembly; low-pressure terminology supplies no numerical operating limit.

Review the supported connection in service

Define the polished finish and production requirements without inferring corrosion resistance or sealing capability from appearance. For the intended water, drainage, fire-protection, gas or petroleum project, provide the medium, numerical duty, cycling and imposed loads. Assess pipe attachment, mating parts, gasket, fasteners, support and assembly together. Confirm PPF-PH applicability, requested customization and the stated three-year warranty terms with the quotation.
