hdpe butt fusion injection equal tee pipe fittings
***Comparison between PE pipe fittings and other piping, Our PE pipe fittings have
the following advantage:
1). Economical efficiency: Low comprehensive fabrication cost, long service life is over 50 years.
2). Corrosion resistance: Anti-corrosion in seawater and alkali soil, no galvanic corrosion.
3). Sanitation: Colorless and tasteless, harmless to human body.
4). Impact resistance: Good impact resistance performance
5). Flexible: Suitable for all topography, non-brake when earthquake and subsidence because of
non-equilibrium section of land.
