specialist chemical manufacturer re-orders niplast tanks after 13 years

Specialist water treatment chemical manufacturer Houseman Limited, has taken delivery of five new chemical storage tanks from Niplast for its new £3m manufacturing facility at Wythenshawe, near Manchester. The new tanks provide bulk storage for Houseman's main raw liquid chemicals and are being used alongside two Niplast tanks supplied in 1983, which have themselves been relocated and re-commissioned.

Because of the trouble-free service provided by the original Niplast tanks, the company was invited to tender for the new vessels. The order was placed in May, valued at c.£40,000.

Each tank provides a working capacity of 20,000 litres, taking deliveries from pressurised road tankers. The differing characteristics of the raw chemicals required each tank to be individually designed, taking account of delivery temperatures, specific gravities, material compatibility, melting points and so on.

Accordingly, four tanks have been manufactured from polypropylene and one from high density polyethylene. Of the five, three have been fitted with frost protection systems, comprising immersion type heaters, rockwool lagging and cladding in the appropriate thermoplastic.

All five tanks share the same main dimensions; 2.5m internal diameter and an overall vertical height of 5.5m. Typically each tank is fitted with level indication, overflow, vent, holding down chairs and sundry flanged connections to suit Houseman’s processes.
