Industrial Piping System
Reason that user requirement for piping system :
1. regulatory acceptance
2. practical installation
3. reliability
4. low maintenance
5. good cleanability
6. easy up grading
7. economical solution
ECTFE and PVDF
ECTFE and PVDF is the two most popular rigid solid wall piping systems mostly due to :
Cost effectiveness and chemical resistance to highly troublesome aggressive fluids
Excellent physical properties :
abrasive resistance
hardness
impact strength
burning rates
brittleness resistance
high mechanical strength
AGRU PVDF-UHP (piping system for the transport of ultra high purity media)
PVDF is an extremely pure polymer and contains no stabilizers (e.g.UV), softeners, lubricants or flame retardant additives in comparison to a lot of other plastics. It is particularly suitable for ultra pure media constructions and distribution system in the industry. Contamination from the piping system is almost impossible because of the excellent leach-out behavior of the PVDF material. AGRU PVDF UHP piping systems have been successfully approved in the semiconductor industry for more than 25 years.
Field Application :
AGRU PURAD system applicable in many areas
• Microelectronic industry and semiconductor factories : requiring very low extractable values
Display factories (LCD,TFT,LED)
Solar cell production PV
Printed circuit board production (PCB)
• Life Science industry
Pharmaceutical industry
Biotechnology
Laboratories and research facilities
Hospitals
Dialysis laboratories
• Food and beverage and dairies industry : requiring low extractables and FDA approved compounds
• Ultra pure and pure water systems
For power plant construction and for different industries (e.g. petrochemical industry …)
• Chemical processing industry
• Pulp and paper industry : in handling halogens and acids
• Nuclear waste processing : in handling radiation and hot acids
• Water and waste water treatment plants : for handling high concentrations of sodium hydrochlorite and membrane filtering system
PVDF homopolymer is the strongest of the pipe lining thermoplastics, strong enough that it can be used as stand alone pipe.
ECTFE piping system
Piping system for the transport of highly aggressive chemicals and ultra high purity media, ECTFE provides excellent chemical resistance and high mechanical strength even at high temperatures.
These characteristics enable the use of ECTFE as a cost effective solution for many applications with ultra pure media.
Advantages of the ECTFE system :
ECTFE shows a remarkable hardiness and excellent chemical resistance to most organic and in organic chemicals (pH value 0 to 14, max 140°C) as well as solvents (max. 120°C)
• Sulphuric acid H2SO4 98 %
• Hydrochloric acid HCL 37 %
• Hydrofluoric acid HF 90 %
• Sodium hydroxide NaOH 50 %
• Hydrogen peroxide H2O2 60 %
• Nitric acid HNO3 65 %
• Solvents
• Chorine and chlorine compounds
ECTFE is distinguished from other materials by its barrier properties. The permeation of oxygen, carbon dioxide, chloric gas or hydrochloric acid is 10 to 100-times better compared to e.g PTFE or FEP.
ECTFE in comparison to PFA : cost efficient in material and installation; smoother surface; higher permeation resistance; larger dimension range (up to 110 mm/ 4inch); and lower heat expansion.
Application range
ECTFE is primarily used in the chemical, semiconductor, photovoltaic, pharmaceutical and petrochemical industries for the following application areas :
• Supply system for chemicals
• Process equipment and distribution piping systems
• Hot ultra-pure water systems
• Double containment piping systems
• H2SO4 injection piping for sewage treatment plants
• Ventilation piping for aggressive media and high purity media
• Lining as corrosion protection for steel, FRP and concrete tanks
Outstanding features
• Stable and highly resistant to crack growth
• Ultra pure and flame resistant (FM 4910 tested raw material; UL94-VO)
• Physiological non toxic application
• Resistant to high pressure
• Resistant to UV and gamma radiation
• Resistant to diffusion and permeation
