ZTZG 150KW High Grade Steel Pipe Milling Machine API 5L Tube Mill Equipment

Tube Conveyor Line Petroleum And Gas Oil Casing High Grade Steel Pipe API 5L Standard Tube Mill

Product Introduction

Straight seam welded pipe mill also is called ERW mill.

The plate in certain width after slitting line and stripping is unfolded and leveled. Then, they are sent into forming machine. Used the roller, the plate is bent into pipe state. The edge of the steel plate is melted by making use of the proximity effect and skin effect of high frequency current. Then, the plate is extruded and welded into the pipe by extruding roller. Then, the final pipe is manufactured out after the IF annealing, fly-saw and sizing. API standard straight seam HF welded pipe mill introduction is mainly used for producing the high grade pipe such as oil, gas delivering and casing pipe in the oil well. These high grade pipes strictly require the pipe material and pipe quality. This kind of straight seam HF welded pipe mill has IF annealing, air cooling roller rail, UT detector, high pressure hydrotester, diameter drifter and other detect equipments and art craft.

Application

Annual output of 200,000 tons of N80, P110 steel grade oil special pipe production capacity. As an important equipment for oil and gas drilling and transportation, the special oil pipe is widely used in the connection between drill collar and bit, drilling power transmission, borehole wall support, oil and gas transportation, etc. In recent years, with the continuous increase of oil and gas exploration and development in China, the demand for special oil pipes for medium and high grade and special technical requirements continues to grow.
