Pipe Cap DN850 Sch 40 PE Carbon Steel ASTM A420 WPL6 Fittings ASME B16.9
Carbon Steel Buttweld Pipe Fittings
Pipe Cap DN850 Sch 40 PE Carbon Steel ASTM A420 WPL6 Fittings ASME B16.9 is a high quality bow low cost pipe fittings that commonly used in industry such as natural gas , petroleum, gas and oil pipes, chemical.
The carbon steel pipe caps usually painted with black primer to keep them away form corrosion, and galvanizing surface, PE coating has the same functions. Those are the most common method to prolong the service life of carbon steel buttweld fittings.
