Product Description
DELLOK Carbon Steel Welded Nailhead Tube
DELLOK (YONGHUI RADIATING PIPE MANUFACTURING CO., LTD.) specializes in manufacturing high-quality welded nailhead tubes, also known as studded tubes, designed for demanding industrial heat transfer applications.
Product Overview
Carbon steel welded nailhead tubes are engineered as alternatives to finned tubes for heat transfer in processing industries. They excel in corrosive environments and applications with dirty gas streams that require frequent or aggressive cleaning.
Technical Specifications
| Parameter | Specification |
|---|---|
| Tube Outer Diameter | 25-273 mm |
| Tube Wall Thickness | 3.5-28.6 mm |
| Tube Length | Up to 25,000 mm |
| Stud Height | 10-35 mm |
| Stud Pitch | 8-30 mm |
Manufacturing Process
Studs are automatically resistance welded to the tube using PLC-controlled equipment, producing high-quality forge welds with minimal heat-affected zones. The process allows combination of various material grades including carbon steel, low alloy, stainless steels, and high nickel alloys.
Key Advantages
- Heat exchange efficiency equivalent to 2-3 times that of bare pipe
- Easy cleaning capability for dirty flue gas environments
- Increased film heat transfer coefficient
- Reduced number of bare pipes required (1 studded pipe replaces 4-10 bare pipes)
- Suitable for harsh temperature and corrosive environments
- Can be cleaned efficiently by shot blasting without material damage
Applications
Studded tubes are primarily used in fired heaters, furnaces, gas turbines, and boilers within petroleum refineries and petrochemical plants where heavy fouling and corrosive conditions are present.
Quality Assurance
DELLOK implements comprehensive quality control throughout the entire production process, including raw material inspection, production monitoring, water pressure testing, and strength verification. All batches undergo sampling and testing with maintained records.
Company Profile
Established in 2002, DELLOK operates with 200+ employees, 33 technical staff, and features 47 fin tube production lines with annual capacity exceeding 12 million meters.
