Features

The single-layer FBE coated steel pipe has properties of high electric strength, acid resistance, alkali resistance, long service life, high quality and salt tolerance. Due to these advantages, our range of product can be utilized as electrical conduits, chemical resistant pipes, etc.

Due to low impact resistance, bad bend ability and high water absorption rate, this range of steel tube cannot be fixed in a place where the groundwater level is high. The FBE coated layer can be classified into ordinary level and strengthened level.

Inspection methods

The exterior appearance of the steel pipe coated should be visually inspected. Smooth surface, even color, no bubbles, no cracks and no shrinkage symbolize the qualified FBE coated steel pipe.

The magnetic thickness gauge is utilized to measure the thickness of the four points which are equally distributed around the circumference orientation of three randomly selected places.

The leakage inspection is employed by on-line detection of EDM spark locations. The set value for voltage is 5v/um.
