High Strength Alloyd Horizontal directional drilling pipe tooling for HDD machine

Charater of drilling pipe

the features of a high quality HDT pipe are durability, accuracy and manage ability. these pipes are

made from cold drawn piping,
providing a superior surface finish and tolerance compared to conventional pipes made from hot rolled

piping. This drastically reduces the risk of scaling from the pipes entering the hammer, a major cause of

premature hammer failure.
The joints are friction welded to achieve maximum strength,and the threads of the end-pieces are heat

treated for optimum durabilityand strength of the thread profile. This not only ensures long thread life, but also

makes coupling and uncoupling quick and simple,reducing drilling time.

but also makes coupling and uncoupling quick and simple, reducing drilling time.
Pipe diameter should be close to the hammer diameter to provide optimum flushing, reducing the

chances of getting stuck.In most applications, standard API threads will be the best choice. SANSUNG also

offers a wide range of subs and crossover subs to meet an array of demands, all manufactured to the same

standards as the pipes.
The high pressure air is delivered to DTH hammer by DTH drill pipe, simultaneously it transfers the rotation

and press force to the DTH hammer.

Standard DTH drill pipe:
Diameter: 76mm, 89mm, 102mm, 114mm, 127mm, 140mm, 152mm
Length: 1000mm, 1500mm, 2000mm, 3000mm, 5000mm, 6000mm
Thread: 2 3/8" API REG, 2 7/8" API REG, 3 1/2" API REG, 4 1/2" API REG, 2 3/8 API IF, 3 1/2 API IF
Special DTH drill pipe:
The drill pipe for Atlas Copco - Ingersol Rand T4, Schramm T64, Atlas Copco F6, L6 and L8, and the drill pipe for Sandvik

WUXI JINQIU MACHINERY CO.,LTD was founded in June 1969. it is located in No.99Qianluo road

Qianqiao town Huishan district Wuxi city. It is at Wuxi Vocation park. It mainly produces hydraulic press brake,

hydraulic shear, CNC sheet V grooving machine, allotype surface quick forming machine, CNC hydraulic turret

punching machine and other series products. It is one of the backbone enterprises in the domestic forging

industry with 40 years’ history.

The company covers an area of 62000 square meters with over 50000 square meters construction area.

It have advanced production equipments with imported large CNC gantry milling machine, imported large

CNC boring and milling machine, 100T carriageway and a series of iconic devices.

Company’s excellent design team can make personalized products according to the user’s demands which

to maximize customer value and optimize customer cost performance. Meanwhile, the company have always

stood in the forefront of technological innovation, continued to explore the “JQ”brand products widely and deeply,

and also attached great importance to the research cooperation. it has established long-term cooperative relations

with Jiangnan university, Nanjing university of Aeronautics and Astronautics, Jiangsu university, and also has set up

long-term stable cooperative relationship with the word’s leading multinational companies. Our hydraulic press brake

and shear machine have formed serialization

To met the customer’s different requirements.

Especially since 2002, the company has continued to increase investment in science and technology, our innovation

ability improves yearly through research staff’s innovation and hard work. We has received dozens of national invention

patents and utility model patents, won the provincial high tech enterprise in 2007, and obtained the innovation and reward

fund support from the national ministry of science and technology in 2011.

The company always adhere to quality system has access to the export product quality permit ISO 9000 international quality

system certification CE certification.

We sincerely hope to establish a close cooperation with domestic and foreign customers.
