Hebei billions of Steel Pipe Manufacturing Co., Ltd. honesty, and seek common development. Production of products: eccentric at both ends of the size of the first nozzle diameter is used to connect different diameter pipe or flange reducers. Both ends of the eccentric head orifice, the center on the same axis, reducers when calculated axis tube position, the position of the tube constant, and generally used for gas or the vertical liquid pipe reducers. The eccentric head at both ends of the circumference of the nozzle endo generally used for the level of the liquid pipeline. Eccentric head tube mouth cut up, known as top-level installation, generally used for the pump inlet, and is conducive to the exhaust, the tangent point down to the bottom level installation, and are generally used for the installation of the control valve, use drained. Eccentric conducive to fluid flow, less fluid state interference in Reducing the gas and vertical flow of liquid pipeline concentric reducer reducer. Eccentric because one side is flat, conducive exhaust or drain, convenient car and maintenance, horizontally mounted liquid pipelines generally with partial company mainly produces specifications for the outside diameter 18-219mm seamless steel pipe, steel pipe material complete structural steel pipes, fluid steel tubes, the other also for customers to build a variety of large-diameter pipe, non-standard steel pipe, steel pipe products produced are the implementation of national standards, applicable engineering, coal mine, textile, electricity, military and other fields. Steel pipe because of its manufacturing process is divided into two kinds of steel pipe and cold drawn (rolled) steel hot-rolled (extrusion). Cold drawn (rolled) tube circular tube shaped tube is divided into two kinds. Two process overview, hot-rolled (extrusion steel pipe): tube round → heating → perforation → three-roll cross rolling, and rolling or extrusion billet tube → detached → sizing (or reducing) → cooling → → straightening straight → hydrostatic test (or testing) → mark → storage. Cold drawn (rolled) steel: round tube → heating → perforated → Heading → annealing → pickling → oiled (copper) → pass cold drawn (cold rolled) → → heat treatment → straightening → hydrostatic blank tube test (testing) → mark → storage. Company with a good reputation, won the trust of high-quality steel pipe products. Welcome to the new and old customers to negotiate and cooperate. The heart diameter pipe.
