NAGAOKA SCREEN, made out of triangular-shaped wedge wires and supporting rods, allows the gas and the liquid flow in the reactors smooth and efficient.
Adjustable slot size offers high slot opening ratio compared with that of
the conventional wire mesh and the slit pipes.
High opening ratio encourages the higher efficiency in process and less clogging in the oil refineries, petrochemical plants and water intake (in case of water wells.)
NAGAOKA offers unique continuous welding technology, ERW, which gives strength and accuracy in our products.
NAGAOKA produces a variety of screens ranging from a cylindrical- shape screen to a flat panel. NAGAOKA SCREEN, with reinforcement stiffeners and/or material alteration, offers high resistance to severe temperature and pressure.
All NAGAOKA’s products are designed, manufactured, inspected and shipped in accordance with the ISO9001/2008 quality management system.
The NAGAOKA SCREEN (Wedge Wire and Support Rod) welded by ERW (Electric Resistance Welding) has sufficient strength to satisfy various customer requirements. The performance of the welded parts has been analyzed and proven by macro, microphotographs and tensile strength tests.
PMI (Positive Material Identification) is performed to ensure the chemical composition of alloy materials confirming to the job requirement for materials used in the reactor internals.
The slot of the NAGAOKA SCREEN is well controlled to ensure accuracy by filler gauge and taper gauge.
