  • Flowserve decoking hoses feature ANSI RTJ flanges on both ends.
  • Flanges are butt-welded to a built-in coupling body that is completely enclosed within hose wall and securely anchored to fabric and wire reinforcement. Hose has unrestricted full flow the entire length.
  • A swivel flange on one end facilitates installation by allowing the hose to freely rotate without disengaging the RTJ flange bolting.
  • Hoses are built to API 7K specifications. Factory-certified visual and hydrostatic test reports with supporting graphs are furnished with each hose.


Size Range: Available in 4,000 psi and 5,000 psi working pressure designs
