Air pipe heads with automatic valves OST 5.5329
Air pipe heads are widely used on any watercraft. They are mounted on oil and fuel tank air pipes. They have a protecting mesh inside. There are two types of air pipe heads: with a floating ball valve and without valve.
According to Russian law, they must be made according to working drawings and OST 5.5329, RMRS 240712.001TU (23.01.2019) and RRR 240712.001TU (02.04.2014) requirements.
Upon customer’s request we can produce air pipe heads of stainless steel or of 02G2S steel (frost-resistant low alloy structural steel used in temperature range from -70 to +450° C.)
At your request we can powder coat these products, all RAL palette colors are available.
All inner diameters suit GOST 8468-6 requirements. RRR and RMRS certificates are available upon request.
