Abrasion Control on Steel Bent Elbow Pipes with Belzona

KHIA ID: 5236
Industry: Steel & Metal Processing (STEL)
Application: VPF-Valves, Pipes and Fittings (VPF)
Substrate: Steel
Customer Location: Mill, South Carolina
Application Date: September 2011
Products:

Belzona 1391 (Ceramic HT)

Problem: Original steel pipes are built with a 2"x4" steel base that supports the bottom of the bent steel pipe. Heavy abrasion discharge from dust and mill operation particles penetrate the cylindrical steel wall surface and erode the base requiring pipe replacement or extensive welding.

Application Situation
Support base of steel bent elbow pipes in a bag house exhaust room of a steel manufcturing facility.
Application Method
Base 2" x 4" x 8' in length had to have a portal hole drillled in order to pour the material and allow it to fill the cavity of the base. Belzona two part material was mixed and poured to fill spaces. Prior to full cure, the portal holes were filled with a screw that was additionally sealed by the Belzona 1391.
Belzona Facts
The customer had not previously coated or filled the metal base of these bent elbow pipes. Consequently, it eroded from high pressure dust and mill exudate discharged from the cylindrical pipe and abrading it's way through the pipe and the base. This required an expensive pipe replacement every 18 months. Three years later, this pipe is still in service offering cost and maintenance savings for the customer.
