PEX is an acronym for cross-linked polyethylene. PEX Tubing is now being widely used for Plumbing and Radiant Heating applications. PEX is desirable due to its flexibility, durability, and thermal memory. Synonyms for PEX include PEX Tubing, PEX Pipe, and PEX Tube.

Cross-linked polyethylene. PEX tubing is commonly used for hydronic radiant floor heat, but increasingly also used for water supply lines. Stronger than PE.

a flexible pipe which is used for hot and cold water lines. There are many benefits to PEX pipe: it is generally quieter than rigid pipe systems, less likely to have scale buildup and is more withstanding in freezing temperatures than rigid pipes.

Acronym for Baltic Sea Patchiness Experiment, an ICES investigation which took place in the Gotland Basin during April through May in 1986 under the leadership of B. Dybern. The basic objective of the experiment was to study the heterogeneous and patchiness in the distribution of physical, chemical and biological properties in the region. Almost all of the Baltic Sea countries contributed to a total of 15 research vessels used in this experiment. The data collected during this experiment can be found at the PEX Web site.
