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 minimum on extra investment. By introducing larger diameters and increased production (up to 1800 kg/hour) in MLFC pipe technology, especially the last 6 years, technologies have developed very fast, solving issues appearing in the years before. MLFC seems to be developed to a next step and the question is, what kind of material can be used in the middle layer. Big programs like Vinyl 2010 and Vinyl plus have created in Europe a large demand for recycled material to be used in the middle layer, but in Europe, due to legislation, more industries tend to use recycled material resulting in high price levels for recycled materials. The main issue not to start in certain countries (and companies) MLFC technology is the materials handling and the “complex “ way of solving this problem. Also in this field, al lot of dedicated solutions are developed in the last 6-10 years to create a massive demand in MLFC technology.

As the cost of raw material is the dominant part of cost price in plastic pipe, pipe producers internally check on scrap rates and overweight to get the lowest cost price. Scrap rates are mostly defined as start-up scrap. But scrap is also production that is in not in spec, production of pipe that has burning spots,...

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...

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...

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...
