Production Description:
Outside the single-layer nodulizing epoxy powder the coating (carries out the SY/T0315-2005 standard) the monolayer nodulizing epoxy powder coating anticorrosion steel pipe is suitable for medium and so on transportation petroleum, natural gas, water, the operating temperature for - 30°c-100°c, this coating has the painting operation simple, not to have the pollution, the coating anti-impact and the bending property is good, the heat resistance higher characteristic, in domestic and foreign obtains the widespread application.
