Spiral steel pipes coated with plastic inside and outside for water supply are a new type of pipe material that uses food grade modified epoxy resin powder to coat the inside and outside of the steel pipes. There is a strong bonding force between the coating layer and the steel pipe, and the surface of the plastic is smooth and beautiful. Due to its low fluid resistance, it can increase flow rate, save energy, and have good anti-corrosion and hygiene performance of the pipe fittings.

Product characteristics of spiral steel pipes coated with plastic inside and outside water supply:

Excellent mechanical performance.

Good corrosion resistance and hygiene performance.

The coefficient of thermal expansion is small and does not shrink or deform.

High compressive strength and working pressure exceeding 1.6Mpa.

Smooth surface, low fluid resistance, no scaling, and unsuitable for microbial growth.

The epoxy coating effectively solves the corrosion of pipelines caused by water transmission, burial, acid, alkali, and salt, and has a long service life.

　　

Connection method of spiral steel pipes coated with plastic inside and outside the water supply:

Supporting groove type pipe joints, malleable iron pipe threaded joints, flange connections, and coating repair free welding methods.

　　

Application scope of spiral steel pipes coated with plastic inside and outside water supply:

It is widely used in drinking water supply pipelines, seawater pipelines, recycled water pipelines, chemical pipelines, buried pipelines, and shipbuilding pipelines.
