Features of SW Kelly bar

●Designed according to advanced Modular-element principle with six ribs laid on tubes.

●The advantages of our Kelly bar, such as low weight, hioh strength,high abrasion-resistance, high-reliablity are safeguarded technologically by superior process, advanced machining equipments and special fixtures.

●All Kelly bars are available in interlocking, friction and partially lockable version. Length, Kelly stub and Kelly eye's dimensiorcan be on request.

●Complete model series and fexible design and manufacture ensure the abiity to supply Kelly bar to matched with any model of drilling rigs.

●Take use of seamless alloy tube imported from Germany Mannesmann or locally-made. Special hot-treatment enhances the material's strength more than 800Mpa.


●Ribs made of alloy hot-treated specially enjoys both high hardness and perfect welding performance, high abrasion-resistanceleads to high-reliability.

●Several service centers and rich experience of repairing Kelly bars on jobsite or in workshop benefit customers to enjoy rapid service.
