φ219×12.7 Oil & Gas Transport (API) Pipe Production Line
Specialized in Pipe Production Line
More than 23 years...
High Frequency (HF) longitudinal welded pipe production line / pipe making machine / tube mill is designed to produce welded pipes of 8mm to 720mm in OD and with a maximum wall thickness of 16mm, as well as corresponding square and rectangular pipe.
Oil & Gas Transport (API) Pipe Production Line
Special oil pipes, crucial equipment for oil and gas drilling and transportation, play a vital role in connecting drill collars and bits, transmitting drilling power, supporting borehole walls, and transporting oil and gas. These pipes are manufactured using a 'ZTF' forming technology on our advanced tube mill production line. Leveraging our strong manufacturing and R&D capabilities, ZTZG has successfully developed and manufactured the world's largest straight welded API pipeline with a 720mm OD for Russia in 2018. This demonstrates our expertise in tube mill technology and our ability to produce high-quality, large-diameter pipes for demanding applications. Our advanced tube mill ensures the precision and efficiency needed for manufacturing top-tier oil and gas pipes.
