S.H PPH Female Thread Connector | S5 1.25MPa Chemical-Grade Hot-Melt Socket to Female Thread Straight Joint (20mm - 63mm)

Xieyu S.H Premium PPH Socket to Female Thread Connectors (S5 / 1.25MPa)

Transition your rigid chemical pipelines seamlessly to threaded instruments, valves, and metal fittings with our premium Xieyu S.H PPH socket to female thread connectors, available at Atradesen.com. Manufactured by Xieyu (S.H / HIEH), a globally recognized leader in high-performance industrial thermoplastic systems, these heavy-duty PPH (Polypropylene Homopolymer) straight joints are engineered to withstand continuous operating pressures up to 1.25 MPa (181 PSI) and temperatures from -20°C to 100°C.

Featuring standard parallel socket depths and a heavy-duty outer reinforcement collar, this female thread connector series is highly compatible with industrial chemical pipelines, acid pickling loops, electroplating lines, waste gas scrubbers, waste acid recovery, and wastewater treatment.

Seamless Socket-to-Female Thread Transitions

In industrial process lines, transitioning from a solid, hot-melt welded pipeline to threaded components—such as pressure gauges, flow meters, metallic adapters, or plastic male-threaded valves—typically requires complex manifold configurations. Our specialized one-piece female thread connector resolves this challenge. One end is a standard smooth socket designed to slip-weld directly onto rigid PPH pipes, while the other end features standard parallel G-threads. The threaded portion is designed with a heavily thickened wall structure to absorb mechanical stress and prevent splitting during high-torque tightening.

High-Integrity PPH Material Qualities

• Chemical & Abrasive Wear Resistance: Molded from high-purity Homopolymer Polypropylene, these S5-rated connectors offer superior chemical resistance to highly corrosive media, organic solvents, strong alkalis, and mineral acids.
• Safe & Potable Certified: PPH is entirely non-toxic, lead-free, and odorless, making these straight joints completely safe for drinking water pipelines, pharmaceutical loops, and food processing lines.
• Easy Molecular Fusion: The smooth, precision-machined internal socket ends are designed for hot-melt socket fusion welding, forming a unified, leak-proof molecular system.

⚠️ Sizing & Installation Guidelines

Nominal pipe dimensions are based on standard outer diameters. Please measure your pipe outer diameter (OD) and plan your socket depth precisely using our dimensional guide:

• Size Specification Layout: The size format (e.g., 20mm x 1/2" to 63mm x 2") represents the outer diameter (OD) of the pipe x the matching nominal thread size:
  • 20mm x 1/2": Socket ID fits 20mm OD pipe; thread matches standard 1/2" male fittings.
  • 25mm x 3/4": Socket ID fits 25mm OD pipe; thread matches standard 3/4" male fittings.
  • 32mm x 1": Socket ID fits 32mm OD pipe; thread matches standard 1" male fittings.
  • 40mm x 1-1/4": Socket ID fits 40mm OD pipe; thread matches standard 1-1/4" male fittings.
  • 50mm x 1-1/2": Socket ID fits 50mm OD pipe; thread matches standard 1-1/2" male fittings.
  • 63mm x 2": Socket ID fits 63mm OD pipe; thread matches standard 2" male fittings.
• Connection Methods:
  • Socket End: Requires standard hot-melt socket fusion welding using professional heating equipment to melt the joints together, securing a completely seamless, leak-proof molecular system. Alternatively, they can be welded using PPH plastic welding rods.
  • Threaded End: Standard G/BSP/PT parallel threads. Always wrap additional PTFE thread seal tape (Teflon tape) clockwise around the mating male thread to secure a watertight mechanical joint.

Frequently Asked Questions (FAQ)

Q: What is the main benefit of using a socket-to-female threaded connector?

A: In chemical piping networks, most process equipment (like dosing pumps, sensors, and metal pipes) features standard male threads. Since rigid PPH pipes require socket fusion welding, this connector serves as the vital bridging transition. It welds permanently onto your PPH line and provides a threaded outlet, allowing direct, reliable assembly without extra joints or reducing sleeves.

Q: Is PPH material fully safe for food processing and potable water?

A: Yes. PPH Homopolymer contains only pure propylene molecules with no toxic chemical additives. It does not release heavy metals or plasticizers, making it fully safe for domestic drinking water loops, pharmaceutical lines, and industrial food processing manifolds.
