Applications
The Liwei steel joint (model DN65-DN3200) is a versatile metal connecting component manufactured from high-quality galvanized steel. Designed to withstand heavy loads across various temperature conditions, it is primarily used for loose sleeve connections of pumps, valves, and other pipeline accessories in multiple industrial applications.
Installation Process
The dismantling joint is suitable for pipelines with flanges on both sides. During installation, the product length at both ends can be adjusted to match flange positions. Diagonal tightening of pressure cap bolts creates an integrated assembly with controlled displacement, facilitating convenient installation, maintenance, and on-site dimensional adjustments.
