PVC pipes and fittings in Saudi Arabia are uPVC and CPVC pipe systems for drainage, sewers, soil and waste stacks, cold water pressure lines and hot water, regulated under SASO’s pipes regulation. This page covers each PVC product and its standard, the SASO certificate and SABER steps, metric sizing, how heat and sunlight affect PVC, Saudi and imported brands, and what drives price and delivery.

PVC pipes and fittings in Saudi Arabia are uPVC and CPVC pipe systems for building drainage, sewers, cold water under pressure and, in CPVC, hot water, and they fall under SASO's pipes regulation, which lists "solid PVC pipes" among its customs items. Within the Saudi pipes and fittings category, this page focuses on PVC alone: the product types, how Saudi heat and sun change them, what the SASO certificate route means for a PVC order, and how buyers in Riyadh, Jeddah and Dammam compare suppliers. Regulatory points were checked in October 2026.
Saudi projects buy uPVC for gravity drainage and sewers, uPVC soil and waste stacks inside buildings, uPVC pressure pipe for cold water and irrigation, CPVC for hot and cold water, and PVC conduit for cables. The standard and class differ for each, so the RFQ has to say which one.
| Product | Where it goes in Saudi Arabia | What to specify |
|---|---|---|
| uPVC non-pressure underground drainage and sewer | Building drainage to the municipal network, housing schemes, industrial city sewers | ISO 21138-2 (smooth outside) or ISO 21138-3 (corrugated outside) structured-wall pipe, both listed in the SASO annex; or solid-wall pipe; stiffness class |
| uPVC soil, waste and vent | Stacks and branches in residential towers, hospitals, hotels and schools | ISO 3633 for systems inside buildings; low and high temperature discharge |
| uPVC pressure pipe | Cold water distribution, farm irrigation mains, pressure drainage | ISO 1452-2 (GSO ISO 1452-2 in the Gulf); pressure class; solvent or rubber ring joints |
| CPVC | Hot and cold water in buildings | SASO-ISO-15877-2, listed in the SASO annex; application class |
| PVC conduit | Cable protection in buildings | Conduit system standard; the SASO annex lists SASO-IEC-60423 for conduit diameters |
For hot water risers many Saudi designers use PP-R pipes for hot and cold water instead of CPVC, and buried pressure water lines above small sizes increasingly move to polyethylene pressure pipe. City mains and large sewers are often ductile iron pipe or GRP pipe. Farms that run PVC sub-mains usually buy them with the drip irrigation system, and conduit goes with the electrical cables package.
PVC pipe and fittings for water, sewage and cable use in Saudi buildings fall under SASO's Technical Regulation for Building Materials Part 5, so each product needs a certificate of conformity or the Saudi Quality Mark before it is sold, and fire water pipe is excluded.
| Requirement in the regulation | What it means for a PVC order | Authority |
|---|---|---|
| Certificate of conformity under the Type 3 model, or the Saudi Quality Mark or equivalent | The certificate must cover the exact product, size range and factory | SASO, through SABER |
| Customs item 3917, which includes solid PVC pipes | Imported PVC pipe is checked against SABER at clearance | SASO and ZATCA customs |
| Annex standards such as SASO-ISO-21138 and SASO-ISO-15877-2 | Test reports should name the standard the certificate was issued against | SASO |
| SI units and the metric nominal diameter series; soft conversion from inch sizes is not accepted | Order metric sizes; inch-based imports may not certify | SASO |
| Plant environmental management (ISO 14001 accepted) | Ask for the factory ISO 14001 certificate | SASO |
| Packing, stacking and transport on trucks suited to long pipe | Delivery terms should state truck type and stacking | SASO |
The annex we read lists drainage and CPVC standards for plastics but does not name ISO 1452 for pressure PVC-U, and SASO states that the products and customs codes on SABER are the current version. For pressure uPVC, check on SABER which standard the conformity body applies to your HS code before you accept an offer. Compliance with the regulation does not replace the Saudi Building Code. Our guide to SASO and SABER certificates walks through product and shipment certificates step by step.
uPVC loses pressure capacity as water temperature rises, and sunlight cuts its impact strength, so selection and storage both matter in the Kingdom's climate, from Riyadh's dry summers to the humid Red Sea and Gulf coasts.
ISO 1452-2 frames uPVC pressure pipe for cold water up to 25 °C, extends to 45 °C for water and waste water with a derating curve, and leaves higher temperatures to agreement with the maker. Water held in Saudi roof tanks or carried in exposed lines can pass 25 °C in summer, so state the design temperature and let the supplier choose the class, or switch to CPVC or PP-R for hot lines.
The Uni-Bell PVC Pipe Association found that sunlight fades PVC and yellows only the outer 0.001 to 0.002 inch, that impact strength is the property that falls, and that tensile strength and stiffness are unaffected. It recommends an opaque, light-coloured cover with ventilation. On Saudi sites keep pipe on shaded racks, handle sun-exposed pipe gently in cool morning hours when it is less brittle, and protect any exposed run. Make solvent joints out of direct sun, because heat speeds evaporation of the cement, and respect the system maker's curing time before the pressure test.
Saudi factories cover most uPVC drainage and pressure sizes, and distributors import European, Turkish and Indian systems, mainly for CPVC and named-brand projects. For imports, the importer of record holds the SASO certificate.
Before awarding, ask for the SABER certificate number and its scope, test reports against the annex standard, the ISO 14001 certificate, confirmation that sizes are metric, and solvent cement data from the same system. Use the manufacturer or an authorised distributor for project volumes and keep stockists for maintenance lots. The supplier sourcing guide for Saudi Arabia and the UAE has a fuller checklist, and you can post a PVC pipe requirement with sizes, class and delivery city to get several offers.
Resin price, wall thickness and certificate status drive most of the difference between offers.
