Sany Heavy Industry: 3960 meters! The world's longest mountain directional drilling crossing is successful!

August 08, 2023

Recently，XugongXZ11000 andXZ6600 Horizontal Directional Drilling Rig Double Machine Opposite Crossing，Complete the world's longest mountain crossing project——Xiangshan Huarun Gas Project，The length of the mountain is 3960 meters.，Break many industry construction records at one stroke。

In recent years, the social economy of Xiangshan in Ningbo, Zhejiang has developed rapidly.，Increasing demand for clean energy。This project is the second phase of high pressure project of Xiangshan Gas Co., Ltd.，Pipeline design pressure 1.6-4.0 MPa，Pipe diameterDN400，Designed annual gas transmission capacity 2.100 million cubic meters。After the laying is completed，It can solve the problem of energy shortage in Xiangshan area。

The gas pipeline project of the directional mountain-crossing section，Total length 3.94 kilometers，It is the longest mountain crossing project in the world.，Spud into rock，Whole course rock stratum construction、The maximum buried depth is 460 meters.，Horizontal drop of 60m，Facing the mountain gushing water、Crushing zone、Hole and fissure、Guide the needle thread、Limited site and other construction problems。

XugongXZ11000、XZ6600 Two super-large tonnage directional drilling rigs face each other across the mountain，Orientation began on February 20.，The rock hardness of the crossing stratum is over 100 MPa.，The mountain height is 400-500 meters，On July 17, the supervisor successfully completed the towback.，Call it a day early。Zero failure in the whole process，High quality and high efficiency，Highly praised by users。

It coincides with the successful crossing of Xiangshan Huarun Gas Project, the world's longest mountain crossing project.，XCMG Foundation invites leaders of industry associations、Expert、More than 50 major customers in the industry and regional benchmarking customers gathered in Xiangshan，On-site observation、Construction technology of AC super-long mountain crossing。At the exchange meeting, XCMG released the introduction of large-tonnage core technology and electric drive drilling rig.，Set off a wave of ordering climax。

Customer meeting，The construction party, Jiaxing Wantong, shared the construction experience on site.：The Xiangshan Mountain passes through 3960 meters.，Because of the strata、There are many unpredictable situations due to geographical location and other reasons.，But with the efforts of all parties,，Five months and 11 days.，Perfect finish。XCMG Horizontal Directional Drilling RigXZ11000 andXZ6600 Two drilling rigs operate with zero failure in the whole process，Finish ahead of schedule，It really saved me a lot of money.。Xugong is truly powerful.、A responsible enterprise，We will buy products later.，I will not hesitate to choose Xugong.。

Sino-Russian natural gas、West-East Gas Transmission Project……A field of natural gas“There is a great shift in the universe”，A large-scale allocation of resources，XCMG Horizontal Directional Drilling Rig Spare No Effort to Drill in Every Mountain、Water crossing，The good news is the witness of XCMG's contribution to the development of the national pipeline network.！
