About the factory
A production base, not a trading layer
Pipe is formed, welded, tested and coated here before it is packed for export. That is the reason we can answer a specification question with a production answer.
Hebei Shengzhun Import & Export Co., Ltd. · Industrial Zone, Hebei Province, China
01 / The company
Supplying pipe the way a buyer reads a specification
Hebei Shengzhun supplies spiral welded steel pipe, anti-corrosion coated pipe, pre-insulated pipe, elbows and flanges, custom fabrication and pipeline project materials to distributors and project buyers worldwide. Production, coating and export logistics are coordinated from one industrial base in Hebei, China.
Orders usually start with a schedule: a diameter, a wall thickness, a steel grade, a standard and a coating condition. The export desk checks that schedule against the mill before a price is issued, so the offer and the mill order describe the same pipe.
For distributors, the same approach applies to mixed shipments: pipe, coated pipe and fabricated lengths can be consolidated in one load, with documents prepared for the destination market.
