What is the greatest depth ever drilled for PVC Pipe
I was asked by a consultant yesterday how far could the put 250mm pvc , typical engineers, what tensile strength, has it been done before, collapse pressure and the std one
Does it meet As1477?
Does it?
The answer is no to the AS1477 question, as soon as we cut, slot, thread or change the pipe in any form then it cannot meet As1477 standard.
As a qualified driller with many years of experience under your belt, you know what works and what doesn’t. You don’t need a bunch of technical information that can be hard to understand. Continue reading “What is the greatest depth ever drilled for PVC Pipe” »
Case Study 37 – Horizontal Drains
We have a call from Drillers World in New South Wales asking if we could slot 100 & 65 class 18 UPVC pipe to a specification that meets the specification for the RTA, this calls for the slotting and supplying of Upvc pipe to meet RTA D&C R40 specification. The design pattern of slotting the pipe calls for a slot that is 1/3 of the pipes circumference; this is impractical due to the diameter of the blades needed to perform this slotting operation.
What we decided to do so the pipe could be slotted efficiently was to submit a different pattern that would produce the same open area and not make any difference to the performance needed on site. The benefits of changing the slot pattern is the job could be produced more efficiently lowering the costs, we could meet the deadline needed and the pipe had a considerable stronger support weight.
