Nanyang Machine developed a new type of coal bed drilling rig

The world's first double-sleeved suit with stand-up ropeless car-mounted coalbed gas drilling rigs was successfully developed at Nanyang Erji Group. This MZJ15/900 specialized coal bed gas drilling rig designed for China's landforms, land conditions, and climate has the advantages of high drilling and production efficiency, good safety performance, and easy operation and transportation. It has won praise from CBM experts and passed the on-site assessment. .
Nanyang No.2 Machine Co., Ltd. has successfully developed a skid-mounted modular CBM rig, and developed a new double-section upright, non-laying, new vehicle-mounted CBM drill with a drilling depth of 1,500 meters and a lifting capacity of 90 tons. The derrick of the drilling rig is 27 meters in height, and it adopts a uniquely designed double-sleeve stand-up, no-rope structure. It does not need to adjust the angle and fix it with a mandrel when installing. It can meet the need for double-rooted drilling while drilling, and at the same time improve the Installation efficiency and drilling efficiency.

Cryogenic valves normally refer to valves with working temperature blow -110℃. It is widely used in LNG, LPG and other low temperature industry. Valves designed for cryogenic services, are specially prepared and designed to overcome these challenges. Appropriate component materials such as 304SS (CF8) and 316SS (CF8M) are normally used for body and trim, offering superior impact strength, and excellent corrosion resistance and heat loss properties. An extended bonnet and gas column design is also normally adopted to provide thermal insulation at the stem seal and stem packing area. At sufficient length, this design feature places the functionality of the stem seal in the vapor zone of the liquid media providing safe and continuous valve operation. A variety of body, trim, seat, and seal materials are available for use in cryogenic service. Customer specified options, such as body cavity vent hole, special extension lengths, and materials are also available upon request.

ZC Cryogenic Gate Valve service up to -196℃. Our in-house computer controlled test facility can certify valves up to 36".
