Although OPVC (equal to PVC-O) exists already for 4 decades, it is only the last 10
years beneficial for production due to better-developed technologies and widespread
acceptance by different standards and norms. The rise of the environmental question
to produce with lower material use, lower energy use and better carbon footprint,
makes OPVC the solution for pipe in the coming years, especially pipes used for
water transportation, potable water as well as waste water.
The advantages of OPVC compared to non-polymer solutions in pipe are fabulous.
Not only the carbon footprint of OPVC is by far much better than traditional solutions
like Ductile Iron, but also corrosion, a major problem in Ductile Iron piping, is history
with OPVC. All other advantages of OPVC are listed and discussed. Newest
information makes that OPVC, for water pipe installations, is even a better solution
than PO solutions like PE100.
To produce OPVC, 4 different technologies are known. There are two off-line
solutions and two in-line solutions developed in the last 40 years. The 4 different
solutions are described and compared to each other.
OPVC is the sustainable and reliable solution with chances to be developed widely.

World wide the MLFC pipe market is growing especially the PVC MLFC pipe market. Standards are established first in Europe, Australia, then the America’s, Japan and recently Asian countries are recently following. The main driver using MLFC pipe is reducing the costs of pipe by using less (virgin) material with a...

PVC-O is the accepted pipe solution for the future. Worldwide, more and more countries go in the direction of PVC-O. The main applications for PVC-O at this moment are potable water, wastewater, irrigation and gas.
PVC-O is produced for many years from the 80’s until 2007 the sizes were in majority small (mainly...
Producing PVC is a competitive market. Unless special products are produced like larger sizes or OPVC, the competiveness is important. Therefore the real issue becomes the saving of cost in producing pipe from PVC. There are many ways of saving costs and that issue must be considered in production companies making...

The acoustic properties of polypropylene, polyethylene and PVC which are widely used in
the automotive, construction and pipe industries were measured. The acoustical parameter
selected for this study is ‘sound transmission loss’. Acoustic tests were conducted using a
Bruel & Kjaer acoustic tube with four microphones...
CSA Z662 is the Standard for the use of plastic pipe in Canadian oil and gas pipeline systems. This paper will give an overview of the recently approved revisions to CSA Z662-11 “Oil and Gas Pipeline Systems”, which will be published next year. These revisions include the following : - RCP Requirements for PE pipe, -...
