SS - STAINLESS STEEL BRAID

PURPOSE
Stainless Steel braided hose can be used in applications involving high temperatures and working pressures. High tensile AISI 304L stainless steel wire is used, to give maximum pressure resistance and external protection to the hose.

PB - POLYPROPYLENE BRAID

PURPOSE
Polypropylene braided hose is often preferred to SS in applications involving frequent handling and movement of the hose. PB braid is lighter in weight, and any broken strands will not cut the operator’s hands. In addition, PB braid is not prone to 'chloride stress corrosion', and has generally good chemical resistance.

To ensure *Electrical Continuity* between end fittings, 2 strands of Monel wire earthing strips are criss-crossed on to the liner, underneath the Polypropylene Braid. These are folded back underneath the ferrule at both end fittings, to make an electrical contact.

NOTE: Prolonged exposure to sunlight eventually results in UV degradation of PB braid.

RC - RUBBER COVER

PURPOSE
RC Grade hose is the general purpose product, used in a wide variety of applications. A Black, Antistatic EPDM rubber to extruded over the SS braided product, to protect the SS braid with a tough, abrasion resistant rubber cover. The rubber cover hose has a smooth finish, to make it easy to wipe clean.

A yellow 'CORROLINE' stripe is printed on to the cover. Other texts and coloured stripes are available to special order.

RC Grade hose assemblies are 'FIRE RESISTANT' to BS5173 Section 103.13 Parts 6.2 and 6.3. if Hose Assemblies are further required to be 'FIRE PROOF' this can be achieved by adding double rubber cover end protection to give extra fire protection at the ends of the assembly.

*SPECIAL NOTE*

*ELECTRICAL CONTINUITY*
*Electrical continuity requires that the hose assembly supplied is electrically continuous, or conductive, between metal end fittings at each end of the hose. This can apply whether the hose is GP or AS grade.

The requirements for electrical continuity are specified in the German Document BRG132, and the Specification EN ISO 12115, tested to EN ISO 8031 Clause 3.7, which requires that for hose assemblies with a resistance between fittings of ≤10² ohms, a letter 'M' can be applied, or ≤10⁶ ohms, a letter 'Ω' can be applied.

Corroline Hose Assemblies are all electrically continuous with a resistance of <20 ohms, and therefore meet the requirements of both 'M' and 'Ω', but are not stamped unless requested.
