Mounting hole diameter0.2 inPipe Class125
This polypropylene bolted flange enquiry references DN25 and DN32. Confirm the actual nominal size before ordering: both selectable variants currently use None for pipe size, with Polypropylene or PP material labels. An accepted selected-product drawing is needed to establish the delivered flange.
Match the bore and complete bolting pattern
Specify nominal size, dimensional standard, outside diameter, bore, thickness, bolt-circle diameter, hole quantity and diameter, facing geometry and tolerances. The mounting-hole entry does not provide a complete drilling pattern or identify the flow bore. Match the actual mating flange through the full drawing.
Define the pipe attachment and included components explicitly. Bolted connectivity alone does not establish socket dimensions, thread, welding arrangement or backing-ring supply. Confirm gasket, fasteners and joint acceptance with the selected assembly rather than assuming accessories are included.
Verify the selected polypropylene construction
Request the exact resin or compound grade, product material specification, traceability and required compliance documents. Polypropylene and PP labels do not define reinforcement, moulding condition or certification. Model PPF-PH identifies the enquiry without supplying those technical details.
The photographs include metallic-looking flange examples and a connected disc/ring example. Their appearance cannot confirm the actual polymer product or justify substituting another material. Request the selected-product drawing and confirmation image. Mould requires actual production evidence, while Smooth gives no measured roughness, coating or cleanliness guarantee.
Document the class and complete operating duty
Class 125 requires its governing standard, selected material and temperature basis; it is not a universal 125-psi guarantee. Assess medium composition, temperature, pressure cycles and the complete flange joint against accepted documentation. Enquire with the chosen size, drilling/facing drawing, polymer documentation, attachment details, joint components and actual duty for quotation.
