Scope of work:
Design and build hydraulic ring main (fixed steel welded tube) for the distribution of hydraulic fluid from the hydraulic power units on the ground floor to all hydraulic valve stands and their distribution pipe work to the hydraulic actuators, from ground level to 17 metre level on boilers one and two.
All pipe work complied with BS EN 13480 pipe category 'O' was fully welded using socket weld 3000 lb fittings, Tungsten Inert Gas with Argon purge. The system was pressure tested to 200 Bar and then flushed to NAS Class < 3.
Identification of Pipelines
All hydraulic pipe work was identified using the following colour coding to BS 1710/BS 4800:
The entire pipe is to be painted in the base coat colour and the paint is to be applied using one coat of the appropriate primer followed by two coats of alkyd gloss. Identification banding shall be 100mm wide, and applied at intervals not greater than 2m apart. Banding shall also be placed before and after every bend or offset, at both sides of valves, service appliances, bulkheads, wall penetrations and at any other place where identification is deemed necessary.
All quality control paper work was submitted and approved on handover of the system to the client.
Additional Work:
Turner Hydraulic Group were also commissioned to flush the gas oil pipe work within the plant as an additional undertaking.

Identification of Pipelines
All hydraulic pipe work was identified using the following colour coding to BS 1710/BS 4800:
- Hydraulic fluids that are oil based (including water glycol and invert emulsion). Basic identification colour is to be brown colour code 06 C 39, with salmon pink banding colour code 04 C 33.
- Hydraulic systems utilising HFA fluids (>80% water). Basic identification colour is to be green colour code 12045, with salmon pink banding colour code 04 C 33.
