Like Bioflex Ultra, Corroline+ hose is designed to fulfil all the requirements for use as a chemical hose or industrial hose, but with the added benefit that it has been reinforced to withstand the most severe conditions of physical abuse. Corroline+ is as crush proof and kinkproof as a flexible hose can be, because it is recognised that applications exist in chemical and general process fluid plants where such usage conditions apply.

Introduction

Corroline+ hose was designed and developed to provide customers with a universal chemical hose product which combined all the requirements they had requested for chemical plant applications, particularly the need for improved flexibility and kink resistance.

Corroline+ hose provides a superior alternative to the wide variety of alternative Chemical Hose products currently available.

HOSE CONSTRUCTION

Corroline+ is built around a unique PTFE hose liner design, which has a slightly rippled smooth bore inside, but convoluted outside to generate excellent flexibility combined with “hoop strength”. Grade GP hose has a natural (clear) PTFE liner tube and Grade AS hose has an antistatic (Black) PTFE liner tube.
A stainless helical wire is wound in to the external convolutions, which adds to the kink resistance, crush resistance and the resistance of the hose to both pressure and vacuum.
This reinforced PTFE Liner construction is strong enough to withstand vacuum to -0.9bar and kinking without the need for either internal convolutions or the need to bond the liner to an outer cover, making it an ideal hose liner design, and a significant improvement upon standard products currently available.
The PTFE liner is then further reinforced with a 304 SS wire braid. A smooth finish black antistatic EPDM rubber cover is extruded over the braid, which includes a helical reinforcement wire encapsulated in the rubber cover which renders the hose kinkproof. The rubber cover has a mirror smooth surface finish to aid cleaning, and the antistatic rubber is specially compounded to make the hose ‘fireproof’.

Corroline+ Hose – The best Flexible Hose for Chemical Plant Applications.

PROPERTIES

Pressure and Temperature Limitations

Maximum Working Pressures – as listed above apply from -40°C (-40°F) up to the maximum operating temperature of 150°C (302°F).
Burst Pressures – The hose burst pressures are equal to or more than the maximum working pressures × 4.
Vacuum Limitations:
Usable at vacuum to -0.9bar up to 150˚C/302˚F.
Flexibility:
Much less force to bend than any other smooth bore PTFE lined hose product.
Kinkproof
Much more resistant to kinking than any other smooth bore PTFE lined hose product, and much more kink resistant than the previous Corroline product.
Fire resistance
Corroline+ hose is Fireproof to BS5173 Section 103.13 Parts 6.2 and 6.3, and Corroline+ hose assemblies can be upgraded to Fireproof by applying DBK 300 at each end. All assemblies comply with the flammability requirement as set out in EN 16643.
‘Rolling U’ Flex Life Test
More than 100 × the flex life to failure compared with all other types of smooth bore PTFE, FEP and PFA lined rubber covered hose products.
Flow rates
More than 2 times the flow rates for convoluted bore hose designs. Consult Aflex Hose for specific flow rate information.
Gas permeability
Reduced gas permeability compared with other PTFE lined hose designs, due to the heavy compression applied to the PTFE during processing, which reduces porosity.

SPECIFICATIONS AND PROPERTIES

*The 1/2” and 3/4” size hoses do not include the helical wire embedded in the rubber
** Longer lengths may be available, to special order.
