Pipe stands save wear and tear on machinery, reduce strain on operators and makes the fusion process easier. They're adjustable for uneven terrain so that the pipe is supported at the same height as the machine. By bringing the pipe in parallel to the machine it is much easier to adjust hi/low and achieve a square face-off.
Pipe stands can greatly increase productivity. Instead of moving the machine for each joint, fused pipe can be pulled through the machine allowing a new stick to be rolled in for fusion. This allows all the pipe to be staged in one location keeping the fusion machine stationary, minimizing down time between fusion joints.
August 2018 amendments by the California Office of Environmental Health Hazard Assessment (OEHHA) for the provision of "clear and reasonable" Proposition 65 warnings in Title 27, California Code of Regulations, Section 25600, et seq ("Warning") placed responsibility for providing warnings on product manufacturers, producers, packagers, importers, suppliers, and distributors.
While nothing has changed with McElroy's products, the requirements for warnings have evolved. For specific chemical information please contact firstname.lastname@example.org.
