Discount Nylon Piping Supplier & Factory

Nylon 6 / MC Nylon absorbs ambient humidity up to 6–7% at total water saturation, which results in a linear dimensional expansion of approximately 0.2% to 0.3% per 1% of water uptake. For high-precision hydraulic sleeves operating submerged in water, we recommend either increasing machining clearance allowances, specifying oil-filled formulations, or switching to POM (Polyacetal) or UHMWPE, which exhibit water absorption rates below 0.2%.

Burst and continuous operating pressure ratings are governed by Barlow’s formula: P = (2 * S * t) / D, where S is allowable design hoop stress (typically 20-25 MPa at room temperature with safety factor), t is wall thickness, and D is outside diameter. While heavy-walled thick cast tubes easily withstand 50+ bar in hydraulic actuator sleeves, small pneumatic tubes handle up to 25 bar. For extreme hydraulic pressures, fiber-wound or metal-braided nylon reinforcements are suggested.

Yes. Through our specialized centrifugal and static mold fabrication methods, we can produce customized outer diameters ranging from 30mm up to 1200mm, with wall thicknesses starting from 5mm upwards. We also offer precision finish CNC hollow-turning for custom non-standard bores and high concentricity requirements.

Cast Nylon (PA6) has superior tensile resilience, high shock absorption, and greater resistance to abrasive foreign particles, making it ideal for large equipment sheaves and heavy-duty sliding sleeves. POM offers superior dimensional stability in wet environments and lower initial static break-away friction. Choose Cast Nylon for heavy abrasive loads and POM for precision moisture-tight components.

Employ sharp, polished high-speed steel (HSS) or uncoated fine-grain tungsten carbide tools with generous positive rake angles (15° to 30°) and clearance angles (10° to 15°). Because nylon has low thermal conductivity, high continuous feed rates with flood soluble oil coolants or air jets are mandatory to prevent localized friction heat from softening or gumming the polymer.
