Spiral pin - Import export

SPIROL’s heavy duty & fatigue resistant Coiled Spring Pins are available in diameters ranging from 1.5mm (.062") up to 20mm (.750"). Standard materials include high carbon steel, 302/304 nickel (austenitic) stainless steel, and 420 chrome (martensitic) stainless steel. Diameters larger than 12mm (.500") are available in 6150 alloy steel. SPIROL invented the Coiled Spring Pin in 1948. Coiled Pins are available in light duty, standard duty and heavy duty to match the required strength and flexibility for each application. A pin too strong for the applied load will not flex and may damage the hole. A pin that is too flexible may fatigue prematurely within the assembly. The Coiled Pin with the optimal balance of strength, flexibility and diameter will result in the prolonged useful life of the assembly.

Liquid gas hose per DIN EN 1762 (LPG), however with embedded spiral for smallest bending radiuses and very easy handling. For propane, butane and other liquid gasses per DIN 51622. Also suitable to transport gaseous media. For information on temperature and media resistances please see our Simon resistances chart. Construction: Black, electrically conductive special tube Tension and pressure-resistant fabric inlays Embedded copper wire Concealed steel spiral Pin-pricked, weather-resistant, electrically conductive, abrasion-resistant cover Interior and exterior smooth, fabric patterned Supplied by the roll or cut to length. Available as drum-windable or simple loading or drainage hose, also without spiral. Other versions and dimensions on request.
