PureBond® Weldable Pipe System
The PureBond® weldable pipe system from Entegris is a state-of-the-art patented method for joining PFA pipe, fittings, valves and other fluid handling devices into an ultra clean, chemically resistant, leak-free fluid delivery network. Our pipe welding expertise provides you quality weldable pipe products, technical support and training. With the weldable pipe system from Entegris, you have the flexibility of designing and assembling your system yourself, or we can produce a complete fluid management assembly for you.
| The Material |
| |
| PFA is a chemically inert, strong, moldable and extrudable plastic material. The properties make it safe and dependable for handling a wide range of high purity, aggressive and corrosive chemicals. |
| The Product |
| |
| Entegris offers a wide range of sizes (from 1/4" to 2"), a wide range of components (valves, fittings, pipe, adapters, filter housings) and the design expertise to provide complete fluid management systems for your applications. The product is made of a dense, ultra clean plastic and can be used for a wide range of chemicals at a wide range of application temperatures and pressures. |
| The Process |
| |
| Patented PureBond® welding is a unique noncontact, butt-fusible process. Entegris provides the necessary tools to butt-fuse all components in a leak-free network. The welding tool allows for the proper cutting, facing and heating of components to be joined into whatever design is needed. |
| The Benefits |
| |
| With PureBond® weldable pipe your system is leak free. |
| |
PureBond® weldable pipe joints eliminate threads so there is no danger of cold flow and its resultant leakage. |
| |
The joints are as strong as the pipe, eliminating potential leak paths common to threaded systems. |
| With PureBond® weldable pipe your system is versatile. |
| |
PureBond® products allow you to handle volatile chemicals, in wide serviceable temperatures and pressures. |
| |
PureBond® pipe, fittings and valves are adaptable to connect with any system. For example, they can be used with tubing and with NPT threaded systems. |
| |
PureBond® pipe, fittings and valves are designed to be welded to create any length or size fluid handling unit. |
| With PureBond® weldable pipe your system is chemically compatible and inert. |
| |
PureBond® products are chemically compatible and inert because they are made of virgin PFA. They ensure your system delivers the cleanest possible chemicals. |
| |
PureBond® products of virgin PFA will not contaminate your chemicals or pure water. |
| |
PureBond® products will not compromise your samples. |
| Installation |
| |
| PureBond® welding equipment is portable and simple to use. Each welding tool is used for the different sizes of pipe, fittings and valves. |
| |
| The PureBond® welding tool holds pipe, fittings and valves in proper alignment. A facing tool presets the distance the parts extend into the welding tool with a flat and smooth surface. A guided slide mechanism holds the parts together while the material cools, joining the components permanently. A noncontact heater is centered by guides on the welding tool. Preset locking prevents molten ends from being pressed too far together. PureBond® welding tools provide bonds of consistent quality. |
| |
| PureBond® welding pipe installation, maintenance, repairs or changes can be made by your personnel. |
| Training |
| |
| Along with the welding tool, Entegris provides a complete video training program and a companion operation and troubleshooting guide. The process is easy to understand. Operator expertise is developed enabling the complete welding of fluid management systems using Entegris PFA components. |
