Production Description:
Outside the double-decked nodulizing epoxy powder the coating (carries out the Q/CNPC38-2002 standard) the double-decked nodulizing epoxy powder coating anticorrosion steel pipe to be suitable for medium and so on transportation petroleum, natural gas, water, the operating temperature - 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.
