Ultra Pure Water Piping Material

SEKISUI

Ultra Pure Water Pipe, Fitting, Valve: •ESLON Clean Pipe features excellent elution, and is an economic ultra pure water clean piping material.; •We supply ESLON clean pipe, fitting and valve to make high clean purity and flow constant.

Name	Material	Size	Use Temp.	Maximum Allowable Pressure	Joining Method	Application
Super ESLON Clean Pipe	HI-PVC Impact Resistance	13~300A	0~+60℃	1.0Mpa	TS Jointing Socket Fusion	Ultra Pure Water Pipe

Features: •Achievement of very little TOC & metal elution through unique PVC mixing and forming technology
•Very suitable to ultra pure water pipe because of very little elution of TOC, metal and various ions
•Prevention of proliferation of live bacteria and pollution because of very smooth surface profile of the inside of pipe

The figures were measured with the short tube sealing water testing method created by Japanese semiconductor technology research association.

Smooth internal surface prevents proliferaion of live bacteria and pollution.
Pipe Size	13~150	200~300
Surface Profile Rmax/	≤0.25μm	≤0.30μm

Picture of the internal profile taken by electron microscope: •Using MMP's automatic socket fusion machine for joining does not require adhesives and it helps to accomplish better elution performance.
•Because of its excellent chemical resistance, durability, and thermal properties, it can be suitable for not only ultra pure water but general chemcial pipes.
•Linear expansion coefficient is 1/2 of that of PP or PVDF, and thus thermal expansion and contraction are easy.
