What is ASTM C1147?
It is the standard practice for determining the short-term tensile weld strength of chemical resistant thermoplastics. It covers the preparation and evaluation of joints between two pieces of weldable grades of thermoplastic materials, backed and unbacked, up to 2" in thickness.

How do PKG’s plastic fabricators remain ASTM C1147 qualified?
At least once a year, the welders prepare and are tested on specimens of each combination of plastics and welding equipment for which PKG seeks qualification.

What’s the largest tank PKG can manufacture?
There are no real restrictions on how large we can make the tanks other than what is legally transportable over the road. We can also fabricate a tank in sections and then field-weld the tank.

What are the differences between XLPE tanks and HDLPE tanks?
The basic differences are in the molecular structure of the materials, which produces performance differences. XLPE, due to the linking of polymer chains, provides superior impact, abrasion, environmental stress cracking, and notch resistance over the linear material.

Where are the pictures of Bill Mitchell?
