TWI accreditation

Lee Dervan and Mark Richardson, fabrication technicians at Simpson Thomson Filtration (STF) which manufactures Niplast Tanks, successfully completed the assessment following a two-day hot gas and extrusion welding qualification programme to BS EN 13067, for welding polypropylene and polyethylene. The team’s acknowledged skills in welding thermoplastic sheet and pipe offer customers guaranteed quality assurance and further confidence in the manufacture of Niplast Storage Tanks.

During discussion with TWI, STF identified the delivery of hot gas and extrusion welding, and butt fusion and socket fusion as areas for skill consolidation and recognition.  STF also saw a benefit in qualifying all of their skilled fabrication technicians to BS EN 13067 ‘Approval Testing of Plastic Welders’, which could offer a lever into new market opportunities where welding certification is required.
