Buying PVC SCH 40 Wholesale — FAQ
What does PVC SCH 40 mean and where is it used?
Schedule 40 is a wall-thickness class for PVC pipe — thicker than SCH 20, thinner than SCH 80. This line is pressure-rated SCH 40 (ASTM D1785) for cold-water conveyance: residential plumbing, commercial buildings, hotels, pools and spas, and industrial cold-water service at ambient temperature. It is not for hot water and not for compressed gas — those are different specs (CPVC for hot water, dedicated industrial spec for gas).
What is the working pressure across the 1/2" to 6" range?
Working pressure runs from 600 PSI at 1/2" down to 180 PSI at 6". The pattern is consistent — larger diameter, lower working pressure — because the wall thickness scales with the diameter rather than holding constant. Full table: 1/2" 600, 3/4" 480, 1" 450, 1-1/4" 370, 1-1/2" 330, 2" 280, 3" 260, 4" 220, 6" 180. Pipe ships in 6-meter lengths across the line.
What does ASTM D1785 cover?
ASTM D1785 is the international specification for pressure-rated PVC pipe at SCH 40, SCH 80, and SCH 120 walls — the same standard plumbing supply houses already buy against. The production and testing protocols cover dimensions, hydrostatic burst, drop impact, flattening, and pipe-stiffness checks; lots are produced and inspected to those targets. Plant also runs ISO 9001 (quality), ISO 14001 (environmental), and ISO 45001 (health and safety) systems, with BASC for secure trade.
Why injection-molded fittings instead of formed fittings?
Injection-molding produces a fitting in a single shot under controlled wall thickness and dimensional tolerance — no welds, no formed seams, no thinned sections in the bend radius. For pressure service that matters: the failure point on a formed fitting is usually the seam, and injection-molded fittings remove that variable. The trade-off is tooling cost up-front, which is why injection-molded fittings cover the high-volume sizes; very large or very specialized configurations stay fabricated.
Can this pipe carry hot water?
No. SCH 40 pressure PVC is rated for cold water at ambient temperature only — typically up to about 73°F (23°C) at full rated pressure, with the pressure rating dropping sharply as temperature rises. Hot-water lines use CPVC, PEX, or copper. The brochure language — "pressurized cold water at ambient temperature" — is the spec, not marketing.
What solvent cement do you recommend for the joints?
For SCH 40 PVC joints the brochure references Weld-On 705 PVC cement with C-49 cleaner; for CPVC service the 713 cement applies. Standard practice is to deburr and chamfer the cut, clean the surfaces with the dedicated cleaner, apply cement to both the pipe end and the fitting socket, push together with a quarter-turn, and hold. Cure times and pressure-test windows are on the cement label and vary by diameter and temperature.
What sizes do you stock and what is the minimum order?
Full 1/2" to 6" pipe range and the fittings catalog are available on order — coverage is by the container, not retail single-stick. Fittings include 90° and 45° elbows, tees and crosses, reducers, couplings, MPT and FPT adapters, caps, bushings, eccentric reducers, and compact ball valves through 2". The honest framing on minimum: if the math works for a dedicated PVC SCH 40 container, we book it that way; if not, we mix with plastic pallets, insulated bins, or safety-line products to get to a clean landed cost. Send the SKU mix and destination — we put the configuration together.
Is this line for the United States, LATAM, or both?
Both. Voltiera ships SCH 40 pipe and fittings on the LATAM and Caribbean routes and into the United States on the wholesale-by-container model. ASTM D1785 is the same standard plumbing supply houses already buy against, so the spec lands without translation. Pool and spa supply is a steady use case in Florida; cold-water plumbing is the volume application everywhere.
