Studded Tube
Studded Tube is a welded steel pipe with studs fused to its outer surface, manufactured from carbon steel equivalent to Q235 or ASTM A36 and supplied in standard lengths for heat‑transfer equipment. The supplier notes that export‑grade tubes meet international standards such as ASTM A178 and are shipped with mill test certificates for quality assurance. A series of studs are welded equally around the circumference, with square or hexagonal patterns designed to increase the heat‑transfer surface area.
In the tubing industry, carbon‑steel studs of this type are typically produced to ASTM A178 specifications, with outer diameters ranging from 50 mm to 200 mm and wall thicknesses between 4 mm and 12 mm (typical). Stud diameters are commonly 10 mm to 20 mm, spaced 30 mm to 100 mm centre‑to‑centre, and the tubes are offered in lengths of 6 m to 12 m (typical). These dimensions provide a balance of mechanical strength and enhanced thermal performance for high‑viscosity oil, heavy oil and other medium‑viscosity fluids.
The tubes are used in power‑plant boilers, petrochemical refinery heat exchangers and large‑scale HVAC systems where improved heat transfer is critical. EPC contractors, plant operators and equipment manufacturers source them in bulk for new installations or retrofits. Segment Industrial Development Co., Ltd. trades the product in metric‑ton quantities; buyers should request the minimum order weight, preferred Incoterms and payment terms directly from the supplier.

Prospective purchasers should confirm the factory’s quality‑control procedures and any third‑party testing capabilities before proceeding.
Studded tubes are specialized welded steel tubes with studs fused to the outer surface using automatic stud welding machines, designed to maximize heat transfer area in boilers, heat exchangers, and thermal equipment. These carbon steel or alloy studded pipes are widely used in power plants, petrochemical refineries, and HVAC systems, serving as critical components in thermal transfer applications. Export-grade studded tubes meet international standards such as ASTM A178 or equivalent, and are typically supplied in standard lengths with mill test certificates for quality assurance in global trade.

Sourcing Studded Tube from Segment Industrial Development Co., Ltd. - China Import Guide
Prior to ordering, confirm the carbon‑steel grade, ASTM A178 compliance and the dimensions of both the tube and the studs to ensure they meet your heat‑exchange design criteria. Request a recent mill test certificate and, if necessary, a sample of the welded joint to verify welding quality and stud attachment strength.
Shipping from Jiangyin will typically involve inland transport to a Chinese port such as Shanghai or Ningbo; the supplier has not disclosed lead times or preferred Incoterms, so buyers should ask for the expected shipment schedule, the Incoterm (e.g., FOB or CIF), and the payment method such as LC or T/T.
Arrange for a pre‑shipment inspection or third‑party quality audit to verify dimensions, stud integrity and material certification. Ensure the Mill Test Certificate and any additional test reports are included with the commercial invoice and packing list to facilitate customs clearance and downstream quality assurance.
