3m Long DTH Drill Pipe

A 3m Long DTH Drill Pipe is a specialized drilling component used in various industries for creating boreholes or drill holes in the earth's subsurface. These drill pipes are designed to work in conjunction with DTH hammers and drill bits to facilitate drilling operations.

PRODUCT INTRODUCTION

PRODUCT INTRODUCTION

A 3m Long DTH Drill Pipe is a tubular component used in drilling operations, particularly in the fields of mining, construction, geotechnical engineering, and oil and gas exploration. Drill pipes serve as conduits for transmitting drilling fluids, such as mud or air, and provide a path for the drill bit to penetrate the earth's subsurface.

The production process of 3m Long DTH Drill Pipe usually includes the following main steps:

Drill pipe cutting: Cutting a single pipe body of equal length from a seamless steel pipe. These seamless steel pipes are usually formed by hot extrusion of cylindrical steel, and the composition of the steel pipe is tested.

 

Drill pipe upsetting: The two ends of the drill pipe are thickened, and the two ends of the pipe body are heated by a medium frequency furnace. Then, some materials on the steel pipe are added to the two ends by hot extrusion, which is called upsetting.

 

Drill pipe machining 1: Rough machining of the two ends of the pipe body.

 

Drill pipe tempering: Heat treatment process is carried out to improve the overall mechanical properties of the down-the-hole drill pipe, so that it has strong hardness and good plasticity and toughness. The tempering process includes austenitization, quenching and tempering. But different dth drill pipes manufacturers have different levels

 

Drill pipe testing: Mechanical properties of the customized dth drill pipes after tempering are tested, mainly including hardness testing and organization analysis.

 

Drill rod straightening: Since the drill rod may be deformed during the quenching process, it is restored by straightening.

 

Drill rod ultrasonic flaw detection: Use ultrasonic flaw detection technology to check the surface and internal defects of metal materials and some non-metallic materials.

 

Drill rod machining 2: Turn the external thread and internal thread at both ends of the drill rod for connection.

 

Coating: The DTH drill rod after machining should be painted to prevent the china dth drill pipes body from rusting and improve the appearance of the product.

 

Drill pipe packaging: After all processing procedures are completed, the product is packaged and sold to customers.

 

 

How To Chose The DTH Drilling Tools?

When using a new 3m Long DTH Drill Pipe, ensure the saver sub is also close to new to ensure the best possible connection. Before using the pipe for the first time, remember that each connection should also be made up and broken out three times after proper application of thread grease. This will help avoid wear and galling.

 

Make up the connection using the manufacturer's recommended make-up torque. Make up gradually to avoid overheating and damaging the thread.
 
Do not exceed the bend radius parameters of the pipe. Overbending the pipe dramatically shortens its lifespan even if it may not lead to immediate failure.water well drill pipe For sale
 
Rotate the 3m Long DTH Drill Pipe through the drill string from job to job. The lead pipe is subject to relatively greater stress and wear, so change it each time to help ensure even wear throughout your pipe stock.
 
Do not clamp on any part of the pipe body. This could damage the pipe and reduce its lifespan.
 
Damaged threads damage connections throughout the drill string. Grease every joint, every time, and check threads after use for dirt or damage. When the pipes are not in use, clean the threads, grease and protect them with a thread cap. Always use professional HDD thread grease and
drilling fluids.
 
Avoid mixing 3m Long DTH Drill Pipe from different manufacturers, as variations in manufacturing tolerances may cause problems with makeup and lead to pipe damage. Pipes with a pronounced age difference or obvious difference in the state of wear also should not be mixed.
 
Check the pipes regularly for wear and tear. Check and change adaptor subs and sub savers in good time: these low-cost items help protect the entire drill string from premature wear.
 
Use a starter rod between the drill string and the reamer, especially a large reamer.

warning

Heavy lifting.

Take care when handling the hammer. The hammer and its internal components are heavy and difficult to handle, especially in the case of larger hammers. When lifting using mechanical lifting equipment, sling the hammer. Alternatively, a liftingeye coupling can be screwed onto the top sub.

 

Transportation.
Do not let the hammer lie unsecured on a vehicle or drill rig. Always
secure the hammer for transportation.
