General Description

The ingredients used in low toxic PVC compounds which are converted into products for food contact by our compounders, are selected from widely accepted lists issued by organisations such as UK BPP/BIBRA Code of Practice, German BGVV Recommendations and the US Code of Federal Regulations. The directives issued from time to time by The European Commission, on acceptable additives to be used with plastic materials, are being regularly monitored,. When appropriate, Copely will take whatever steps are required to comply with new recommendations when they are issued.

The regulations specifically ensure that the compounds are cadmium free. (Copely were perhaps the first to have a cadmium free specification some 10 years ago).

Our Quality System fully conforms to BS EN ISO 9002 certification and DQS (Deutsche Gesellshaft zur Zertifizierung Qualitatssiche Rungssytemen MBH).

In addition to the above we have a specialist material for the conveyance of beer, cool fluids and semi-fluid foodstuffs - for further information please contact our Sales Office.

(It should be noted that as the application detail is outside the control of Copely Developments, it is the responsibility of the end user to demonstrate the compatibility of the hose with whatever food product is to be conveyed. Statutory instrument No. 1523 requires that there is no deterioration of organoleptic characteristics of the food when in contact with the hose. Such requirements can be met by carrying out appropriate migration tests.)

braiding angle

Braiding and Braid Angles

The angle of application of the reinforcing fibres, irrespective of the denier, is critical in the achievement of a 'balanced' pressure hose. Copely manufacture hose with a target angle of 54° 44' (54.73°) being the optimum angle. Variations to the angles are generally for economic reasons, but major variations will have a marked effect on the performance and longevity of the product.

Relationship between Temperature and Working Pressure of CR Reinforced Hoses

The Pressure/Temperature graph provides a guide to the reduced pressure capability expected from the hose when operating at elevated temperatures.

If the temperature is exceeded extreme caution should be exercised and strict account taken of all operating parameters.

Example:-
From the graph
if-- WP @ 20ºC = 12 bar (100%)
then-- WP @ 50ºC = 12 x 55%
= 6.6 bar

Relationship of Bend Radius to Hose Diameter

The graph gives a general guide to the limit of bend capability of the hose. Tighter radii are possible but caution should be exercised if it is used, as this may lead to some flow restriction.


Safety Factors

When selecting a hose for an application it is important that an adequate safety factor is allowed. This will vary according to the type of service envisaged and below is an extract from ISO 7751:1997 to assist an installer in providing a proven level of safety.

Type of Service

Safety Factor
(Ratio of min. BP to Design WP)
Water hose, max. WP 10 bar 3.0
Hose for all other liquids, solids suspended in liquid or air and water hose, WP over 10 bar 4.0
Hose for compressed air and other gases 4.0
Hose for liquid media that change into a gaseous state when subjected to a reduction in pressure. ie released to atmosphere 5.0
Jetting hose 2.5
