جدول Ruisongbuild 40 & 80 بولي كلوريد الفينيل 90 Degree Elbow ASTM D2466 1/4 Bend

Description

Ruisongbuild ASTM PVC 90° Elbows: The Industry Standard for 1/4 Bends

The 90-degree elbow is the essential component for changing direction in any rigid piping network. At Ruisongbuild, our ASTM standard PVC 90° elbows (commonly called Quarter Bends in the US) are injection-molded for superior wall thickness uniformity and burst strength. Designed for the North American Iron Pipe Size (IPS) system, these fittings offer a seamless, permanent solvent-welded joint for a wide array of pressurized and gravity-fed applications.

المواصفات الفنية & Engineering Standards

• مادة: High-Impact Unplasticized PVC (يو بي في سي).

• Manufacturing Standards: ASTM D2466 (جدول 40) / ASTM D2467 (جدول 80).

• Dimensions: IPS (Iron Pipe Size) system, measured in Inches.

• Common Names: 90 Elbow, 90° Bend, 1/4 Bend, Quarter Bend.

• Connection Type: Slip x Slip (Socket x Socket).

• Pressure Ratings: Varies by pipe size and Schedule (Sch 80 offers higher PSI).

• Color Identification: White (Sch 40) & Industrial Gray (Sch 80).

Why Ruisongbuild 90° Elbows Excel?

• True Interference Fit: Our sockets are designed with a precision-engineered taper, ensuring a snug fit that facilitates a perfect chemical weld with ASTM pipes.

• Superior Material Purity: 100% lead-free and non-toxic, meeting all health requirements for potable (drinking) water and delicate aquaculture environments.

• Maximum Flow Rate: The internal radius is optimized to minimize turbulence and maintain consistent system pressure throughout the turn.

• Rugged Durability: Resistant to UV degradation (White Sch 40) and highly aggressive chemicals (Gray Sch 80), ensuring a 50+ year service life.

Primary Applications

• Residential & Commercial Plumbing: Drinking water mains and household plumbing.

• Swimming Pools & Hot Tubs: High-flow circulation systems (typically White Sch 40).

• Industrial Process Piping: Corrosive fluid transport and plant infrastructure (typically Gray Sch 80).

• Irrigation Systems: Mainlines and lateral grids for landscaping and agriculture.

Comparison: جدول 40 vs. جدول 80 Elbows

• Sch 40 (White): Standard wall thickness. Best for home use, irrigation, and pools. Most cost-effective.

• Sch 80 (Gray): Extra-thick wall. Best for industrial high-pressure pumping and chemical lines. Higher cost but maximum safety.

Frequently Asked Questions

Q1: What is a “1/4 Bend” in PVC fittings?
A: In North America, a 1/4 bend is simply another name for a 90-degree elbow. It refers to the turn being one-quarter of a full 360-degree circle.

Q2: Can I connect an ASTM 90° elbow to a Metric (DIN) pipe?
A: لا. ASTM fittings use the imperial system (inches), while DIN fittings use the metric system (millimeters). A 2-inch ASTM elbow will not fit a 50mm or 63mm DIN pipe. You must stay within the same standard for a secure fit.

Q3: Are these 90-degree elbows safe for potable water?
A: Yes. Ruisongbuild ASTM PVC fittings are lead-free, non-toxic, and safe for drinking water distribution, aquaculture, and hydroponic systems.

Q4: Do I need to use primer before gluing the elbow?
A: Yes. For a permanent, leak-proof bond, we highly recommend using a PVC primer followed by solvent cement. The primer cleans and pre-softens the surface, ensuring a true chemical weld.

Q5: What is a “Slip x Slip” connection?
A: A “Slip” connection is a smooth socket that slides over the end of the pipe. It is the standard connection for PVC systems that are permanently joined using solvent cement.
