Stable Services’ Integral
Bladed Stabilisers are manufactured from AISI 4145H
modified steel. All Stabilisers are bored, drifted
and fully heat treated to meet or exceed the mechanical
property requirements of NS-1. A through-wall hardness
range of 285–341 HB and a charpy “V” notch
impact strength of 42 joules at 20ºC are guaranteed
one inch below the surface. Stabilisers are available
in both “open” design and “tight” design,
near bit or string, and can be supplied in alloy or
non-magnetic steel.

All API connections comply with dimensional requirements
specified in API spec 7 and API RP 7G. Common sizes
and styles are summarised in the table below. Premium
connections
