Product Description
DELLOK Resistance Welding Studded Tube
DELLOK studded tubes are manufactured using advanced resistance welding technology to create high-performance heat transfer components for demanding industrial applications.
Manufacturing Excellence
DELLOK (YONGHUI RADIATING PIPE MANUFACTURING CO.,LTD.) has been a leading manufacturer since 2002, operating from Jiangsu, China. With 66 million yuan in fixed assets and over 200 employees including 33 technical staff, we maintain comprehensive quality control throughout the entire production process.
Resistance Welding Technology
Our studded tubes are created through electrical resistance welding where studs are manually forced onto the tube during the welding process, creating an exceptionally strong mechanical bond suitable for high-pressure and high-temperature applications.
Key Advantages
- Excellent mechanical resistance - withstands frequent high-pressure cleaning
- Superior heat transfer efficiency - equivalent to 2-3 times bare pipe performance
- Complete corrosion protection - studs entirely cover the base tube
- High temperature capability - suitable for extreme operating conditions
