Product Description

Hot Rolling Seamless Pipe Making Machine for Oil Casing and Drill Pipe

Everyone is used to naming hot-rolled seamless pipe mills with mandrels for the wall forming process, such as MPM mills and Assel mills. There are two main types of pipe rolling mills, one is a continuous rolling mill, and the other is a cross rolling mill. According to the mandrel operation mode, the continuous rolling mill can be divided into three types: floating mandrel, limited mandrel and semi-floating mandrel. The limited mandrel mill can be divided into two-roll type (MPM) and three-roll type (PQF). The skew rolling mill is divided into three-high rolling mill (Assel) and two-high rolling mill (Accu Roll).
The oil casing production line of our company uses the world's advanced technology to produce qualified hot-rolled seamless steel tubes. It is used to produce oil well drill pipe, oil casing, oil and natural gas transmission pipe, as well as common transmission pipeline and structural pipe. In line with the principle of advanced technology, reasonable technology, compact structure and saving investment, the heating furnace adopts convenient and efficient ring heating furnace, the main machines adopt the modern advanced perforator, Accu-Roll precision pipe rolling machine, 18 frames reducer, and the six rolls straightener.
