Product Description

Introduction

Kelly bar is the key part of a drilling machine, and its quality directly affects the performance of the whole machine.Based on the rich manufacturing experience and by absorbing the advanced technology both at home and abroad, we can produce first-class kelly bar which can be compared favorably with the imported ones. Interlocking Kelly bars are used with piling rigs for drilling in dense sand and gravel and weak to strong rock. The Interlocking Kelly bars manufactured by UNIMATE can be fully locked by mechanical locking system on each section. Kelly bars can be equipped with specially designed springs or pressure plates for shock absorbing purpose.

The features of SUNY kelly bar are as follows:

1-Adopt the advanced technology of 6-key design in the world and standard modular design.

2-Equipped with advanced processing facilities,processing technic and manufacturing equipments, SUNY kelly bar enjoys a low weight,high strength,high straightness of single bar,thinner tube,smaller inter-tube distance and good abrasion resistance.

3-The raw materials are either imported from Germany like the high abrasion resistance materials,or from Chinese top manufacturer such as the seamless steel tube with alloy. All the tubes made in China are specially made seamless alloy tube,which guarantees the accuracy of the sizes,location,physical properties and easy welding. The small-diameter tubes undergo reheat treatment,which strength is up to 800kg level. The friction kelly bar can be used under full torque.

4-All the outer keys have undergone special heat treatment.Therefore,they possess higher hardness,higher flexibility ad excellent welding properties,which provide higher abrasion resistance to the keys.
