EN877 Cast iron pipe The paint test

SML Cast Iron Drainage System EN877 SML Cast Iron Pipe

The external surface of the Soil pipes are coated to a minimum average of 40 microns but this is only considered a primary coat under the provisions of BS EN 877. This coating requires over coating with a high quality, paint suitable for outdoor use on metallic surfaces when used in an external situation. This is essential to provide an adequate level of protection for the system. It is important to note that regular inspection and re-coating of the products may be necessary.

Hubless Cast Iron Soil Pipe The intrnal surface has a minimum average coating thickness of 130 microns. This enables the Halifax Drain pipes to withstand a variety of tests designed to reproduce the conditions that the products will encounter in their working life. This includes a 30-day waste water test at 23˚C, a 30-day chemical resistance test at both PH 2 and PH 12 and a 1500 cycles water temperature test between 15˚C and 93˚C.
