Naylor Denlok Manufacturing Process
1) Locally-quarried raw materials are accurately blended before being ground to a fine form to enable subsequent extrusion.
2) Clay raw material is mixed with water to give plasticity for extrusion. High-pressure extrusion ensures that a strong dense pipe body is produced.
Close attention to drying to remove moisture is undertaken prior to firing under accurate temperature control.
3) Use of special highly-insulated kilns is employed for attaining accurate firing.
The special qualities of vitrification of the pipe body are attained at a firing temperature in excess of 1050 deg c.
4) After the firing and subsequent grading processes the pipe ends are accurately machined with computer-controlled diamond profile cutters.
Accurate production of parallel ends is also achieved.
6) Intermediate inspection takes place as well as pipe ends being pressure tested to ensure integrity of pipe material. The joint components are then applied and materials are packed for shipment.
Delivery and Site Handling
Pipes are despatched in unit packs that are made up using timber spacer boards and frameworks to ensure that there is no pipe-to-pipe contact.
Unit packs can be handled by forklift to facilitate offloading and site storage. If packs are to be offloaded using lifting slings then advice of this method of handling must be notified to us for loading purposes.
Close attention to packing for transportation and overseas shipment is part of the Naylor delivery service.
It is a major recommendation that all unit packs must be kept assembled with all protection intact until ths pipe is ready for us.
All Denlok pipes and elastomer components are resistant to heat, ozone and ultra voilet light.
