WTPS
주식회사 더블유티피에스 (WTPS Co., Ltd.) is South Korea's pioneering manufacturer of patented ball-type angle-adjustable expansion and contraction pipe joints for municipal water mains, industrial infrastructure, and high-rise commercial MEP systems. Headquartered in Jeonju with state-of-the-art manufacturing in Iksan, Jeollabuk-do, WTPS miniaturizes automotive suspension 'Ball Joint' technology into high-pressure water piping — allowing 360-degree rotation and multi-axis displacement buffering against seismic tremors, foundation settlement, and sinkholes.
- Automotive-grade 'Ball Joint' innovation — allows continuous 360° rotation and up to 15° angular dynamic deflection without leakage
- Anti-seismic & anti-sinkhole structural resilience — absorbs multi-axis ground movement, thermal expansion, and mechanical vibrations
- 100% Weldless mechanical installation — slashes site installation time by 70% with zero fire hazards and zero internal coating damage
- Officially certified by PPS Korea as Innovative Prototype — validated for public water supply networks and high-risk critical infrastructure
- Comprehensive pressure & sizing range — DN50 to DN600, PN16/PN25/PN40 with 30+ year service life
HIASHI is the official MEP specification and sourcing partner for WTPS ball-type expansion pipe joints in Vietnam.
