Note: PureBond weldable pipe products are specifically designed, tested and characterized from a material standpoint to work with PureBond fitting and pipe components manufactured by Entegris. Customer assumes the risk of proper fit and weld connection integrity if PureBond weldable pipe products are connected to components manufactured by third parties. Further, customer will assume the risk of proper fit and weld connection integrity if PureBond weldable pipe products are joined using tools that are not either manufactured by or endorsed in writing by Entegris.
PureBond weldable PFA pipe is suitable for high-purity, high corrosive chemical handling applications where a permanent connection is required including:
Semiconductor, chemical and other industries where purity and corrosion resistance are necessary

Shipping, Storage and Handling
PureBond pipe components are shipped with protective coverings to reduce the possibility of contamination and prevent damage. The pipe sections (10 foot or 3 meters) are capped at both ends and placed in a protective poly bag. They are then placed in a shipping container for safe delivery.
The poly bag surrounding PureBond pipe products should be left intact until that part is needed. This will help prevent particulate contamination.If the parts are to be placed in storage, keep them in a clean, dry area. Only store pipe in the horizontal position with continuous support. This will eliminate any problems associated with bowed pipe and damaged ends.
Never carelessly handle PureBond piping components. By throwing,dropping and dragging these parts, damage and contamination can occur. Keep hands and tools free of dust, dirt, oil and grease. Cleanliness is of utmost importance for a successful installation.
Thermal Expansion and Contraction
- Thermal expansion and contraction of PureBond pipe should be considered during the system design and installation stages. Any significant temperature changes from the installed temperature will affect the pipe length. One common guideline is to install the pipe when it is within 10° to 15°F of its operating temperature. When this is not practical, a thorough examination of the piping layout should be made.
- Small changes may be tolerated because of the lower modulus of elasticity and inherent stress relaxation property of PFA. When large changes are present they should be compensated for in the piping layout. To determine the extend of the length change, a formula is used that takes into account the coefficient of linear thermal expansion of the specific material. The formula is:
Δ = L • ΔT • C
LWhere: ΔL = Length change, inches Ymax = Original length, inches ΔT = Change in temperature, °F C = Coefficient of thermal expansion, In./In./°F for PFA 70° - 212°F = 6.7 × 10-5 212° - 300°F = 9.4 × 10-5 300° - 408°F = 11.1 × 10-5 - An easy rule of thumb for estimating the length change is to assume that for every 10°F change, a change of one inch will occur in any 100 foot linear length. When substantial length changes are evident, they must be compensated for by the use of flexible sections, expansion loops, expansion joints, etc. Should this prove to be a concern in your piping system, contact Entegris for advice in properly incorporating these options.
