On August 2, 2026, Qingdao Huashida Machinery Co., Ltd., a professional supplier of pipe anti-corrosion coating equipment and steel pipe surface treatment equipment, officially won the bidding project of DN6600 large-diameter longitudinal welded pipe coating production line from Qinglong Pipe Industry Group Guangdong Branch. The project covers customized complete equipment for internal FBE fusion bonded epoxy powder coating and external cement mortar spraying for ultra-large steel pipes, specially designed for water conservancy steel pipe anti-corrosion and municipal pipeline engineering.
As a well-known listed enterprise established in 1975, Qinglong Pipe Industry Group has extremely strict standards for equipment procurement and suppliers. Huashida has maintained a 20-year strategic cooperative partnershipwith the group, which has purchased multiple sets of thermal insulation pipe production equipmentfrom Huashida, building solid mutual trust for this cooperation. The group focuses on municipal water supply and drainage pipelines and water conservancy engineering, requiring high-precision and high-stability industrial pipe coating equipment and automated pipeline coating machineryfor large-scale infrastructure project construction.
The awarded DN6600 longitudinal welded pipe FBE/cement mortar composite coating production line adopts advanced one-time heating double-sided coating technology and integrated double-layer anti-corrosion process. Fully automated and high-efficiency, the equipment delivers stable coating quality and long service life, perfectly meeting the manufacturing requirements of long-distance municipal water transmission projects and pressure pipeline prefabrication. It is a high-performance customized pipe anti-corrosion solution for super-large diameter steel pipes.
During the whole bidding process, Qinglong Group conducted strict factory inspections and technical evaluations on all competing pipe coating machinery suppliers and industrial anti-corrosion equipment manufacturers. Huashida stood out remarkably with its strong R&D capability, mature manufacturing technology and strict quality control system. The optimized steel pipe anti-corrosion coating production line solution accurately solved the common technical pain points of traditional FBE coating and cement mortar spraying equipment for large pipes, effectively improving pipeline anti-corrosion efficiency and finished product qualification rate.
In the technical defense session, Huashida’s professional team gave precise and reliable answers to all technical questions, fully demonstrating its profound accumulation in large-diameter pipe anti-corrosion equipment and custom pipeline coating production line. Finally, Huashida won the bid with outstanding comprehensive scores, further consolidating its leading status in the large-scale pipe coating equipment manufacturing industry for municipal and water conservancy anti-corrosion fields.
