Shenhao has been committed to development and manufacture of seamless steel tubes since 2007. Three modernized production lines i.e. φ60, φ120, and φ159 hot rolling lines have been established here for production of seamless carbon and alloy steel tubing, seamless line tubes, oil casing and tubing and other steel tubular products. Every year, these production lines can make 300,000 tons seamless steel pipes in φ48-219×4-40mm specifications and all kinds of steel grades.
We have two workshops for making seamless tubes. Each one has RQ hot rolling production lines and automatic rolling production lines. The RQ hot rolling line covers an area of 40,000 square meters.
The company covers a total area of 200,000m2, including office, production, warehouse, machining and staff living areas. 860 employees work here, 36 senior engineers included.
First Production Line
The first seamless pipes production line covers an area of 50,000m2, including 20,000m2 workshop area. We have equipped the workshop with overhead traveling crane, air compressor, air dryer, transformer, saw machine, electronic truck scale, tilting furnace, water supply system, φ140 perforating machine, φ140 automatic tube rolling unit, φ400 stretch reducing machine, φ160 straightening machine, NEM180 eddy current testing machine, cooling bed, rolling conveyor, monitoring station, pusher, cutting table, etc.
Second Production Line
Floor area of this plant is 40000m2. It is equipped with manufacturing workshop, electrical distribution room, hardware storage and air compressor plant. Equipment in the workshop includes φ13.5 natural gas annular furnace, φ140 perforating machine unit, etc. Annul seamless steel tube output of the production line reaches up to 100000 tons
Third Production Line
This production line comes with relatively small size. It is mainly used to produce seamless tubes with small diameters. Equipment in the workshop is basically the same with that of the first and second production lines.
