MAN L21/31 – Pipe Clamp (Code 1621702-2.2)

Written by

The pipe clamp with code 1621702-2.2 is a fastening and support element designed to securely fix pipes within the MAN L21/31 engine installation. Its role is to stabilize pipelines carrying fuel, lubricating oil, cooling water, or air, preventing unwanted movement caused by vibration, pressure changes, or thermal expansion. Robust in design and resistant to corrosion, this clamp enhances system safety, minimizes fatigue-related failures, and supports an orderly, durable piping layout in marine and industrial engine environments.

MAN L21/31 – Sleeves (Code EN170H13)

Written by

Sleeves identified by code EN170H13 are precision-machined components used in the MAN L21/31 engine to provide alignment, wear protection, and dimensional stability between mating parts. Typically installed in high-load or high-friction zones, these sleeves act as protective interfaces that safeguard major engine components from direct wear. Made from high-quality alloy steel, they offer excellent resistance to abrasion, thermal stress, and mechanical loads, thereby extending service life and reducing maintenance requirements in demanding operating conditions.

The jet assist pipe with code 2196075-0.0 is a specialized auxiliary component in the MAN L21/31 engine, designed to support controlled fluid or air jet delivery within specific engine subsystems. Its primary function is to improve flow behavior by directing a focused jet toward targeted areas, assisting lubrication, cooling, or cleaning processes. Manufactured to withstand pressure, temperature variations, and vibration, the jet assist pipe contributes to enhanced system efficiency, reduced component wear, and reliable engine operation in marine and stationary power applications.
