Stop Logs provide economical means for isolation duties and weir applications where single-piece stop gates would be too heavy to lift or where multiple door sections are required.
STOPLOGS
The Product
Coplastix® Stop Logs are designed and manufactured to suit modern industrial and domestic effluent environments.
The combination of EPDM for sealing and steel/stainless steel allows for versatile Stop Logs in water, sewage, and effluent treatment plants.
Features
General standard size range is 1000mm square up to 2000mm square. Larger and smaller sizes are available. All assemblies are purpose-designed to suit customers' requirements. Stop Logs are only suitable for water pressures up to the height of the top log. Special fixing arrangements can be accommodated.
Material Specification
Frames
Normally supplied in three sections for ease of handling and installation. Manufactured from mild steel to BS EN 10025 : 1993 grade S275 or stainless steel to BS EN 10088:1995 grade 1.4301 (304) or 1.4401 (316) as specified. Mild Steel frames can be protected to suit sea water, potable or sewage conditions. Stainless steel - natural finish.
Frame Seals
Are resilient EPDM (Ethylene Propylene Di Methyl) wiper-type seals having an angled lip seal. Seals are fitted to the seating and unseating sides of the frame. EPDM is chosen for its excellent resistance over neoprene to ultraviolet degradation. The seals are fixed with corrosion-resistant retaining strips and stainless steel fasteners.
Logs
Logs are manufactured as a composite sandwich construction comprising a lightweight rigid, cellular core with a fully welded steel box section matrix between two other skins of rigid, compressed composite plastic which is asbestos free, ultra violet stabilised, rigid and non toxic. All materials are chemically bonded and sealed.
Inter Log Seals
These are twin seals fitted to the bottom edge of each log to permit on or off-seating pressures.
