1. Pulverized Coal Pipe Knee Joint Assembly – Product Overview
A pulverized coal pipe knee joint is an engineered connection component used in coal-fired power generation systems to accommodate directional changes in pulverized coal conveying pipework.
These assemblies operate in demanding industrial environments where abrasive coal particles, elevated temperatures, mechanical stresses, and continuous operation can contribute to component wear.
The correct knee joint assembly must meet the specified dimensional, material, sealing, and mechanical requirements to support reliable operation and maintain the integrity of the coal conveying system.
The 0615097 knee joint assembly, specified for Eskom Matimba, is identified by the supplied engineering details and drawing number 20.58/56003 Rev 0.

8. Important Purchasing Tips
Before purchasing a pulverized coal pipe knee joint assembly, consider the following recommendations.
Verify the Part Number
Confirm that the required component is part number 0615097 and that the application matches the intended installation.
Confirm the Engineering Drawing
Request confirmation that the proposed assembly is compatible with drawing 20.58/56003 Rev 0. Check whether a newer approved revision exists.
Check Dimensions
Verify the specified 610 mm inside diameter and 729 mm outside diameter against the original drawing and existing installation.
Confirm the Material Grade
Do not rely solely on a general description such as high-chromium casting. Obtain the exact approved material designation and supporting material documentation.
Verify the BS4844 Reference
Confirm the intended meaning and applicability of the supplied “22%–28% BS4844” specification with the responsible engineer before ordering.
Inspect the Sealing Arrangement
Ensure that the flexible graphite seal with Inconel insert matches the required 10 × 10 mm specification and the application’s operating conditions.
Confirm Fastener Requirements
Check bolt length, thread, material grade, washer type, and plug configuration before accepting the assembly.
Request Quality Documentation
Depending on the purchase specification, request material certificates, dimensional inspection reports, manufacturing records, and other required quality documentation.
Plan for Lead Times
Specialised castings and drawing-based components may require additional manufacturing and inspection time. Confirm the delivery schedule before committing to a plant shutdown or maintenance programme.
Obtain Engineering Approval
Ensure that any proposed alternative or locally manufactured component receives the necessary technical approval before installation.
