Corroflon

PTFE-lined hose for chemical and process fluid transfer

A fluoroplastic hose with a flexible convoluted PTFE liner. Corroflon has shallow convolutions which minimise the restriction in flow rates, with external wire reinforcement to ensure full vacuum and kink resistance in process applications.

Features and benefits

  • Natural or anti-static patented PTFE liner
  • The shallow convoluted liner design delivers exceptional flexibility while minimising restriction in flow rate
  • Vacuum and kink resistant
  • High temperature and pressure capability
  • Chemical resistant
  • PTFE-lined and non-lined end fittings
  • Range of braid, cover and external protection options available

Purpose

 

For use in applications where the temperature of the process fluid entering the hose assembly must be regulated as it passes through the hose. This is usually required to prevent solidification or an increase in the fluid viscosity. Electrical heating is often preferred to steam heating because it is more convenient, more controllable and usually more readily available. ‘Zone 1 hazardous area’ requirements can be met.

 

Description

 

The heating element comprises a self-regulating element spirally wrapped around the hose assembly. Self-regulating elements may require a sensor and controller if a specific maintain temperature is required. Please consult Aflex Hose for clarification. The power leads and (if applicable) temperature sensor leads emerge from the hose assembly at one end, through glands and conduits. The thermal insulation is foam rubber, closed-cell fire resistant silicone foam rubber for temperatures above 80˚C. The outer cover may be a polypropylene braid or SS wire braid with a EPDM rubber cover.

 

Design

 

Each hose is custom designed and built to suit the requirements of the particular application. Application details must be supplied by filling in an “ETH Hose Questionnaire”, available from Aflex Hose. Generally, for hazardous areas, the self-regulating type of heating element is employed, with or without a temperature sensor and control, and flameproof glands and conduit are also required. The watts per metre of the heating element, the pitch of the spiral on the hose, and the thickness of the thermal insulation are all calculated in accordance with established formulae to give the required maintained temperature for the process fluid passing through.

 

Specifications

 

As for Corroflon GP, SS in Specifications and Properties, except that the minimum bend radius is tripled and the outside diameter and weight are significantly increased in line with the particular design. The maximum length of a CH/ETH hose is 10m (33ft).

 

Limitations

 

1” PTFE lined PN10 flange spigots on heated hoses can only have a maximum flare diameter of 50mm, not 63mm. If the hose is “hanging”, straight or at 90˚, under its own weight, special construction is required, so advise Aflex Hose accordingly. Minimum ETH Hose assembly length, when collars are used 1mtr.
