Import 1656 High-Frequency Welded Pipe Mill Line — Buy in Bulk from Supplier in China

The 1656 high-frequency welded pipe mill line from Hebei Fengqi Machinery is an industrial production system for manufacturing welded steel tubes in the 60 mm to 165 mm outer diameter range. It handles wall thicknesses from 1.2 mm up to 6 mm, using high-frequency induction welding to create longitudinal seam welds at production speed. The line is suited to manufacturers producing structural tubing, mechanical pipe, and conveyance pipe for the construction, general engineering, and oil-and-gas supply sectors.

High-frequency welding is the standard method for producing ERW (electric resistance welded) pipe in this diameter class. The process uses electromagnetic induction to heat the strip edges to forging temperature before squeeze-welding them together, producing a weld seam that, when properly controlled, meets common standards such as API 5L for line pipe or ASTM A500 for structural tubing. Hebei Fengqi states the line includes a user-friendly control panel and energy-efficient motors, though specific motor ratings, forming station counts, and line speed figures are not published in the listing.

Buyers considering this mill line should request detailed equipment specifications, including the number of forming and sizing passes, maximum line speed in metres per minute, installed motor power in kilowatts, and the coil width and thickness the uncoiler accepts. The listing mentions ISO certification but does not specify which standard (ISO 9001 for quality management, for example), so ask Hebei Fengqi to provide the certificate number and issuing body. Pricing, MOQ for a single mill line, and lead time from order to delivery are not stated, and should be negotiated directly with the supplier along with shipping terms such as FOB Tianjin or CIF to your nearest port.

Hebei Fengqi Machinery Co., Ltd. is based in Shijiazhuang City, Hebei Province, China. The supplier listing carries a harbour trust tier on the platform, and the current response rate is recorded at 0%, indicating no tracked responses to buyer enquiries within the platform's measurement period.

The listing describes the company as a supplier of the 1656 pipe mill line but does not provide additional background such as years in operation, factory floor area, number of production lines installed, or export destinations served. Buyers should request a company profile, reference customer list, and details on installation and commissioning support before evaluating this supplier for a capital equipment purchase.
