Drainage is a critical component in any commercial building, and it all begins from the primary area that catches rainwater – the roof. Planned drainage is a vital part of any building, but commercial roofs frequently need more than simple guttering and downspouts. Large and complex commercial roofing systems may require multiple commercial roof drains to channel large amounts of water off the roof and away from the building. Mid-Atlantic Roofing Supply sources only the finest top brand commercial roof drains for any project.

Types ofroof drains

Y-strainers are used in a lot of different fields, depending on the type of product: watering, irrigation for example, but also steam and high-temperature circuits, high pressure, gas circuits, oil industry...

Moreover, the pressure loss is minimal as the fluid goes through the filter normally, without being blocked or forced to slow down.

On the removable stainless-steel screens, the mesh can have different sizes, ranging from 0.15mm to 5mm depending on the products and uses.

Commercial roof drains are made in several common sizes to accommodate various amounts of water. These drains are installed during the roofing process and connected to internal and external drain systems that carry rainwater down and away while keeping it contained from entering the building. Sufficient drainage for a commercial roof is a top engineering priority and is included in architectural drawings and other roof calculations.

Y-type strainers are named after their shape. They are used as filters, preventing dirt and particulates to move inside piping systems. They are set upstream of devices and fixtures such as valves, traps, or pumps.

Syveco offers various models of Y-strainers. They can be in carbon steel, stainless steel, cast steel, or cast iron with epoxy paint. They are fitted with different types of connections: RF PN10/16, PN 40, ANSI 150 or ANSI 300, BSP or NPT threaded, or socket welded. The flanged filters length depends on the EN 558 series 1 (DIN 3202-1 F1 – NF 29354) standard.

The Y-strainer is made up of several parts, the most important ones being the body, the screen (mesh), and the bolted bonnet with draining cap.
