PYZS manufactures both mechanical and hydraulic Liner Hanger. Our mechanical liner hanger features a simple operation, with no pitching ball to build pressure. It completes setting through lifting, corotation and placing down.Applied in vertical and inclined wells, it is a complex completion method combined with multiple sets of tools.

As the oil and gas liner hanger system manufacturer, our hydraulic liner hanger finishes setting by pitching to build pressure. With special tools, the liner hanger and the tail pipe can be sent down into the well’s depth of any design, finishing liner hanger through hydraulic transfer. PYZS liner hangers are widely used in technology and production tail pipe cementing of oil and gas wells, brine wells and geothermal wells. PYZS has improved these liner hangers to produce: sealed liner hanger, a rotatable liner hanger, expandable tubular liner hanger.
