This project is a key renovation project for the old heating pipe network in northern urban areas, with a total pipe laying length of 8.6 kilometers.

This urban heating pipe network renovation project involves the large-scale replacement and upgrade of municipal high-temperature heat transmission pipelines. A large quantity of high-temperature resistant weld neck flanges were supplied for hot water and steam pipeline connections. All flanges adopt integral forging technology, stable sealing performance, capable of long-term operation under continuous high temperature working conditions. Strict dimensional accuracy guarantees on-site welding efficiency. We delivered goods in batches according to the construction schedule, ensuring smooth progress of urban heating reconstruction works.
