Product Description
Manufacturer Profile
DELLOK (YONGHUI RADIATING PIPE MANUFACTURING CO.,LTD.) established in 2002, located in Jiangsu, China. With over 200 employees and 33 technical staff, we operate 4 aluminum processing lines, 5 tube-drawing lines, and 47 fin tube production lines including an imported McElroy system, delivering annual capacity of 20,000+ tons aluminum processing and 12+ million meters fin tube production.
Studded Tube Product Overview
Carbon steel studded tubes feature resistance-welded studs on bare tubes to create enhanced heat transfer surfaces. The studs are mechanically bonded through electrical resistance welding, creating robust connections suitable for high-pressure and high-temperature applications.
Manufacturing Process
Steel studs are automatically resistance welded to tubes using PLC-controlled equipment, enabling combinations of carbon steel, low alloy, stainless steel, and high nickel alloys.
Key Advantages
- Exceptional mechanical resistance withstands high-pressure cleaning
- Superior heat transfer efficiency in demanding environments
- Excellent corrosion protection with full base tube coverage
- High rigidity performance under extreme temperature and pressure conditions
