Process Plant Reinforced Plastic Extraction Systems


Simdean have specialised in the design, fabrication and installation of all types of corrosion resistant all plastic fume extraction systems for many years including small laboratories to turnkey major installations for chemical and industrial plants worldwide.
Systems are designed and manufactured in accordance with the application requirements for a safe and long life system. Some recognised standards include;
SMACNA Thermoplastic duct construction manual
LGC 1614 Ductwork specification
BB88 Fume Cupboards in Schools Section 6 Extraction Systems
BS 7258: Part2: Section 3.2 fume exhaust systems
HVCA DW 151 Specification for Plastic Ductwork
A range of recommendations from the raw material manufacturers.
BS4994-1987 where the process system is large and produces internal pressures.
Materials of construction are dependant on the application and temperature of the process also the fact that the ductwork is installed external or internal to the building and the need for a guard against Ultra Violet Degradation from sunlight etc. With the above in mind the duct system can be fabricated from uPVC, PP, PE, PVDF, Halor and glass reinforced polyester (GRP) throughout or as a cladding to the thermoplastic for added strength usually where the temperatures of the fume are elevated.
Simdean has for many years been an approved fabricator of the material known as CELMAR which is Polypropylene/Glass fibre laminate.
