Direct answer: Pressure Ratings

Pressure Ratings is an ALFA thermoplastic piping product family page. Use it to confirm the referenced standard family, intended service (pressure, gravity, conduit, or hot service), and the documentation needed for submittals—then request sizes/classes against your BOQ.

Selection & procurement checklist

Check	Why it matters
Governing standard on the datasheet/BOQ	Prevents mixing DIN/ASTM/NEMA dimension systems
Pressure class / Schedule / SN	Must match operating pressure or burial load
Jointing system	Solvent weld vs seal ring changes install method and test timing
Media & temperature	Derate or change compound when temperature rises
Fittings & transitions	Metal interfaces need compatible flanges/adapters

Engineering considerations

Do not size from diameter alone. Confirm hydraulic losses, surge, support spacing, UV exposure for above-ground runs, and chemical compatibility. Where numbers are required for design, use the project specification and published dimensional tables—request current ALFA submittals rather than assuming catalog memory.

Standards context

This page may reference international standard families commonly used in Saudi project specifications (for example DIN, ASTM, or NEMA-related conduit standards). ALFA supplies to the standard stated on the order and submittal package—do not infer unstated certifications from this narrative.

Frequently asked questions

What information is needed to quote Pressure Ratings?

Standard, size/pressure class, jointing system, quantities/lengths, fittings list, delivery location, and any submittal/test requirements from the specification.

Can I substitute one pipe standard for another at the same nominal size?

Not without review. Dimensions, pressure classes, and test methods differ across standard families.

How do I contact ALFA for supply?

Use the RFQ form or contact +966 50 183 5126 / sales@alfaalarabia.co. Manufacturing is based at 3rd Industrial City, Jeddah, Kingdom of Saudi Arabia (Aramco Vendor #10116102).
