Key Features

Optimized Rectangular Material Flow: Specifically engineered for square flanges and rectangular chutes. The smooth internal geometric transition effectively prevents bulk powder accumulation and material bridging in heavy gravity drop feeds.

100% Fully Tailored Profiles: No standard mold limitations. We manufacture custom rectangular sleeves and transitional square-to-round shapes precisely matching your non-standard equipment dimensions.

Explosion Safety (ATEX Environment): Optional PUAS Anti-Static selection provides a certified surface resistance less than 10^8 Ohm, safely discharging static electricity in combustible flour, sugar, and organic dust zones.

Extreme Wear & Vibration Resistance: Features an high tensile rating up to 40 MPa to absorb severe mechanical oscillations from vibrating feeders and industrial shaker screens without tearing.

Technical Specs

Material Option PU10 (Standard TPU): Thickness 1.0mm | Temp Range -20°C to +110°C | Tensile Strength 40 MPa | Surface Resistance 10^12 Ohm | Best for Pressure & Vacuum Resistant lines.

Material Option PUAS (Anti-Static PU): Thickness 1.0mm | Temp Range -20°C to +110°C | Tensile Strength 15 MPa | Surface Resistance less than 10^8 Ohm | Best for Flammable and explosive powders.

Material Option PUHT (Heat-Resistant): Thickness 1.0mm | Temp Range -20°C to +150°C | Tensile Strength 40 MPa | Surface Resistance 10^12 Ohm | Best for high-temperature powder discharges.

FAQ

Q: Can SOSHH supply square/rectangular connectors as an alternative to S or B fitting gaps?

A: Yes. While traditional systems have size limitations for non-circular geometries, our factory specializes in premium square expertise. We provide fully customized square-to-square and square-to-round transitional flexible joints with faster delivery and no expensive tooling fees.

Q: Do you provide a certified anti-static version for hazardous chemical or flour handling?

A: Yes. For ATEX compliance, choose our PUAS Antistatic Polyurethane material. It guarantees a surface resistance less than 10^8 Ohm, completely preventing catastrophic dust explosions in bulk solids handling facilities.
