Drain Body/Frame: Weight Capacity 1.5-90 tons

Component Specifications

Definition

The drain body/frame is a precision-engineered structural component that forms the main housing and support structure for floor drains and grates in industrial applications. It serves as the interface between the drainage system and the floor surface, providing load-bearing capacity, proper alignment for grate installation, containment of fluids and debris, and connection to underground drainage piping. This component ensures proper drainage flow while maintaining structural integrity under various operational loads and environmental conditions.

Working Principle

The drain body/frame operates on the principle of gravity-driven fluid collection and containment. It provides a recessed collection basin with sloped surfaces that direct liquids toward the drain outlet. The frame supports the grate above floor level while creating a seal to prevent leakage around the edges. Load distribution is achieved through structural reinforcement that transfers vertical and horizontal forces from the grate to the surrounding floor structure.

Materials

Cast iron (EN-GJL-250, ASTM A48), ductile iron (EN-GJS-500-7, ASTM A536), stainless steel (304/316, ASTM A240), polymer concrete, or reinforced composite materials depending on application requirements.

Frequently Asked Questions

What is the difference between A15 and F900 load classes for drain bodies?

A15 supports 1.5 tons (pedestrian areas) while F900 supports 90 tons (airports/ports). Load class determines material thickness, reinforcement, and installation requirements.

Can polymer concrete drain bodies be used in food manufacturing facilities?

Yes, polymer concrete is corrosion-resistant and meets FDA/EC1935 standards for food contact, making it suitable for food and beverage industries.

How do I ensure proper sealing between drain body and floor?

Use appropriate sealants (epoxy, polyurethane) and follow manufacturer's installation guidelines. Ensure frame is level and properly embedded in concrete with adequate curing time.
