Seamless steel pipe (SMLS) production involves various processes, and regardless of whether the pipes are rolled, extruded, pressed, or spun, billet heating equipment is essential. This makes billet heating equipment a critical component in the seamless steel tube manufacturing process. Here, we discuss the key aspects of seamless steel pipe production equipment.
Types of Seamless Steel Pipes:
Seamless steel tubes produced by these methods include:
Seamless steel tubes for main structures
Seamless steel tubes for hydraulic props
Seamless steel tubes for fluid transmission
Semi-trailer axles
Seamless tubes for axles and half-axle sleeves
Seamless steel tubes for high-pressure boilers
Special seamless steel tubes for oil casing pipes and line pipes
Production Process of Seamless Steel Pipes:
The process starts with rolling steel ingots into round steel. These are then hot pierced to obtain tube blanks (gross tubes), which are subsequently transformed into seamless tubes through hot rolling, cold rolling, or cold drawing.
Various production methods include continuous pipe rolling, periodic pipe rolling, pipe jacking, and extruded pipe production. In each method, round steel or tube billets are heated to the required process temperature using an intermediate frequency heating furnace before entering the rolling process.
Thepipes are then formed by a forming machine or extrusion machine, straightened, shaped, cut, marked, and finally bundled and stored.
Seamless Steel Pipe Production Equipment:
Essential equipment in the production of seamless steelpipes includes:
Blanking sawing machine
Tube billet heating equipment
Intermediate frequency heating furnace
Conical piercing machine
Accu-Roll rolling mill
8-stand three-roll micro-tension reducing machine
Step-by-step cooling bed
Six-roll straightening machine
High-efficiency pipe cutting machine
180mm automatic magnetic flux leakage flaw detection equipment
80MPa hydraulic testing machine
Equipment for measuring length, weighing, spraying, laser marking, and bundling
With these components, seamless steel pipe production can achieve high efficiency and quality, meeting the diverse demands for different types of seamless steel tubes.
