Innovative approachs to assuring quality pipe compounds
Papers # 2012 Barcelona
As significant improvements are made to thermoplastic materials from the first
generation of monomodal pipe compounds to the current generation of high melt
strength, bimodal pipe compounds, signihnt innovations have occurred to assure
quality pipe compounds are produced and used in this industry. One of these
innovations is the means in which material suppliers have utilized technological
improvements to assure consistent incorporation of the additive components in the
pipe compound. The presence of these additive components in the compound is
critical to the processing of the compound into pipe or fittings and subsequently, to
the performance characteristics of the final product.
These additive components may contain antioxidants, acid neutralizers, ultraviolet
stabilizers, hindered amine light (HALS) stabilizers, processing aids, or color
pigments. Individually, these chemical compounds may present safety, health,
and environmental challenges in the consistent incorporation of the additives
during the production of the pipe compound. However, the use of additive blends
(commonly called compressed additive blends or Superblend&) in a physical form
that is conducive for safe handling and feeding provides the material supplier an
excellent means to produce quality pipe compounds.
This paper/presentation introduces the participants to the various types of additive
blends utilized in the thermo~lasticindustrv and orovides ~ i case

The Lake Charles Chemicals Project (LCCP) is a new chemicals plant facility and as a result, corrosion and compatibility as well as cost play a very important role in the selection of piping components. For the purpose of this case study, the focus will be the high density polyethylene (HDPE) piping system used in the...

Color masterbatches or concentrates have been in use with plastic pipes as a means of color coding for identification of pipes by application. The color masterbatch contains not only color pigment(s), but also other ingredients that are necessary to protect the pipe during production and assure long-term durability....
The use of irrigation piping systems has grown significantly in recent years driven by water
shortage and the need to optimize the growth of the global food supply. In the production of
piping products, depending on the application standard being utilized, producer's options for
UV stabilizations include black...

In designing and installing a total piping system, there are many aspects to consider when
one selects the various components that comprise a piping system. One aspect that has
been successfully utilized in the plastics piping industry is the use of colorants to identify
the targeted end-use application of the piping...
In a pipe manufacturing process, extrusion parameters are optimized to assure the
maximum production of quality pipe meeting appropriate standard requirements. As
equipment technology has evolved, the use of grooved feed extruders has created a
significant improvement in the ability of extruders to manufacture quality...
Polyethylene pipe produced from resins meeting the criteria for the PE 100 designation
were first introduced on an international scale in the late 1980’s. Since, that time these
piping products have grown to become recognized as the international standard for longterm performance in the use of polyethylene pipe. The...
