Mud Recyclers

HDD Mud Recycling Systems is applied to urban municipal construction and electrified pipe network transformation. Communication cable laying and the big and small rivers, lake and the horizontal directional crossing construction when the building cannot be demolished, especially in the environmental protection and municipal pipe network expansion project and the horizontal directional crossing construction of large pipeline crossing river project.

The main functions of drilling fluid are to provide hydrostatic pressure to prevent formation fluids from entering and to stabilize the bore, to keep the drill bit cool and clean, to carry drill cuttings back out to the surface, and to suspend the drill cuttings. At the same time, drilling is paused or during the pullback process. Drilling fluid containing excess cuttings can easily damage the pistons, liners, and valves of a mud pump; therefore, it’s critical to clean the fluid down to trace amounts of solids.

Normally, a solids control system consists of a mud tank with compartments for both incoming dirty and cleaning fluid, a shale shaker, a desander (depending upon the size of the unit), and a desilter. The shale shaker separates larger solids, approximately 400 microns and larger, the desander separates solids approximately 100 microns and larger, and the desilter separates solids approximately 40 microns and larger. After the fluid processes through the desilter and is deposited into the clean tank, it can then be pumped to the mud pump to be pumped back downhole.

1.ZLCONN Big HDD factory and workshop.
ZLCON factory more than 60Ksqm,other factories only 6-10Ksqm.ZLCONN uses WL610 steelAll others Q235. WL610 steel is much stronger, much stable than Q235 steel.

2.Self produced parts and full procedure quality control for ZLCONN machine
Many directional drills factories only have assembling workshop.
My factory produce most of the parts all by ourselves, from raw steel sheet dealing – steel sheet cutting – bending – making holes – application – welding- rust removal – electronicphoresis surface treatment – heat treatment – assembling – testing, all by ourselves,much stable,better quality control.

3.ZLCONN Oversea service,EU Standard and Good Price

About Horizontal directional drilling

HDD machines are primarily used for underground pipeline installation and maintenance. Their applications include, but are not limited to, the following:

  1. Oil and gas industry: Used for pipeline laying and maintenance in oil fields and natural gas extraction, including drilling in both horizontal and vertical directions.
  2. Utilities and infrastructure construction: Used for the installation and maintenance of city water supply, drainage, natural gas pipelines, as well as cable and communication lines.
  3. Environmental protection: Used for environmental projects such as groundwater monitoring, soil pollution remediation, and installation of environmental monitoring equipment.
  4. Road and railway construction: Used for laying pipelines in road and railway engineering to avoid disruption to traffic and the surrounding environment.
  5. Construction industry: Used for the installation of underground pipelines, cables, and communication lines at construction sites, as well as for ground reinforcement and underground structure construction.

Horizontal directional drilling machines have a wide range of applications, enabling precise drilling and pipeline installation in underground environments, reducing surface disruption and minimizing impact on the surrounding environment and infrastructure. The stable,powerful ,durable features will decide the speed,efficiency even the sucess of a project. Main parts on horizontal directional drilling machine will include :operating platform,Anchor device,Clamping device, Crawler-tread, Frame assembly, Engine, Diesel tank, Hydraulic system, Hood assembly, push-pull device, Bracket body, Power head assembly, Automatic change rod device, Mud pump assembly Electric system.

How to Choose the right horizontal directional drilling rig?

Regarding pipes or fiber optics in different project are different, for example fiber optics is very small they only need small HDD machine, therefore, for fiber optics normally 22t or 28t is used.

Cable is bigger, so commonly 28t, 35t are more used in cable.

Same for other project, the bigger the pipes are,  the bigger HDD machine are needed.

To learn how HDD machine looks like , how is it produced, how it is operated, how it is working, you can Subscribe our Youtube channel  https://www.youtube.com/@ZLCONNHDDMACHINE/videos

Every different projects need different model of HDD machine, if you don’t know how to choose, pls answer the following questions, our engineer will give you recommendation.

1) What is diameter of the pipe? How many pipe you will pulling at the same time?

2) What is the material of the pipe?

3) What is the max distance from the entrance to exit?

4)  What is the soil condition, hard or soft, clay or rock?

As a top HDD machine manufacturer in China.  it is absolutely right to choose ZLCONN!
