Convoluted Tubing – Extra Flexible Tubing
特曲管非常灵活，特别适用于弯曲半径更小，需要增加压力处理或抗压的应用场合。
Convoluted tubing is very flexible and is ideal for applications where a tighter bend radius, increased pressure handling or crush resistance is needed.
Parker manufactures one of the largest selections of convoluted tubing. Product offerings include MIL Spec Convoluted Tubing for electrical conduit (SAE AS81914), Wire Wrapped Convoluted Tubing to achieve a tighter bend radius, Low Profile Convoluted with a larger inside diameter for increased flow and a Heavy Wall Convoluted that is produced with a thicker wall to reinforce the strength of the tube. The added material in heavy wall convoluted withstands flanging and flaring, allowing the tubing to actually pass through the inside of the fitting so it can be flared over the face of the fitting. This eliminates the problem of bacterial entrapment and adds the benefit of unrestricted flow by providing 100% PTFE coverage on all wetted surfaces. Convoluted tubing's helical constructions are molded into the tubing and will not pull out as the tube is extended. Like other fluoropolymers, Parker convoluted tubing resist corrosive liquids and gases, and has a non-stick surface with low permeability. All of these products can be manufactured with a conductive I.D. or as a fully conductive tube to dissipate static build-up and they are available as bulk tubing or as a cut tube with added cuffs to create an attachable end for adding fittings or flanges.
