FREE CIBSE Accredited CPD

HASL offer FREE CIBSE Accredited CPD: Compensating for thermal expansion, building movement and noise in pipework systems.

This technical seminar provides an insight into the often misunderstood subjects of thermal expansion, building movement and vibration control in piping systems.

Ignoring pipe expansion or building movements can lead to leaks, structural problems, safety issues and additional costs. The seminar shows from first principles how to identify potential problems, the most cost effective ways of compensating for movements utilising both natural flexibility and expansion joints. Correct guiding and anchoring of pipework is critical to the performance of the whole system and the CPD will give practical tips and rules of thumb.

Finally, the seminar will cover the correct selection and application of rubber flexible connections to eliminate noise and vibration transmitted through pipework and media generated by rotating equipment.

This can be arranged either in your office or on site.  If you are interested in a CPD please contact:  [email protected]
