Bolting and Machining

A full range of bolting & machining related services, equipment rentals and sales. Bolt tensioners, torque wrenches, nut splitters, flange spreaders, flange pullers are all stocked. In addition, flange facing services, cold-cutting/beveling machines; subsea aquajacks are available at short notice.

This service is offered in conjunction with Tentec Ltd. of the UK.

The full range of services offered is detailed below.



The CTST range of bolt tensioning tools are some of the most compact and reliable tensioners available today. Below are special features that are incorporated in their design.

All tensioners have polyurethane self-energising lip seals requiring no adjustment. The seals ‘snap fit’ into the piston housing, remain firm and will not dislodge to cause failure after prolonged use. As the seals are machined and not moulded, size is not restricted, allowing no compromise in tensioner design. The TENTEC seal exhibits a much lower coefficient of friction than nitrile seals used in many other hydraulic bolt tensioners. This benefit, in conjunction with a special anti-extrusion device, allows the tool piston/ram to be returned to its closed position with minimal effort.



The Compact-8 range of subsea bolt tensioning tools can be supplied with quick acting Split Reaction Nuts. Simply mount the tensioning tool over the bolt, slide the open reaction nut over the bolt and snap the reaction nut halves together for rapid and reliable assembly. The rapid speed of fit ensures the most efficient use of expensive diver trim.



An Innovative range of Square Drive Hydraulic Torque Wrenches.
The SD-Series from Tentec is an innovative range of square drive conventional hydraulic torque wrenches. The one piece body housing offers rigidity, strength and robustness in a surprisingly lightweight form. The SD-Series torque output ranges from 1722N.m(1270ft.lbs) to a staggering 78625N.m (58000ft.lbs).



Tentec introduces the PN series industrial pneumatic torque wrenches. The new range provides continuous and repeatable torque with an accuracy of +/- 5%. Unlike previous pneumatic torque wrenches, the PN series has the fastest speed when it counts, which is during the actual torque stage and not during the free nut run down stage.

Inherent in all PN Series wrenches is a new gear technology which creates greater durability, lower operational temperatures and increased efficiency. The PN series offers a torque output from 162 N.m (120 ft.lbs) to 8134 N.m (6,000 ft.lbs) and rotational speeds of up to 45 rpm.



Tentec Nuts replace existing hexagon nuts to give a rapid, accurate and uniform Bolt load to any bolted joint. The Tentec Nut offers a method of bolt tensioning multi-bolt applications which greatly improves the integrity of the joint. The speed in which joints can be tensioned and de-tensioned shows an extraordinary time saving over conventional detachable bolt tensioning systems. An existing Oil company user of Tentec Nuts has recently reported a massive time saving of 1750% over their old bolt tensioning system.

    Tentec are a specialist provider of training and competence assurance programs in the assembly and tightening of bolted connections to industries as diverse as oil & gas (onshore and offshore), power generation, construction, defence and renewable energy.

    Tentec deliver training in controlled bolting in accordance with “Mechanical Joint Integrity Standards” document published by the Engineering Construction Industry Training Board (ECITB). The training standards available are MJI10 hand torque, MJI18 hydraulic tensioning and MJI19 hydraulic torque wrenches. Additional Tentec derived courses include TE12 Hydraulic Nuts and TE13 BTS-Bolt Tightening Software

    These standards are recognised by industry and recommended as the benchmark qualification for bolting personnel by The Energy Institute and other influential authorities



    Takes the complexity out of Bolt Tightening Calculations.

    Tentec software allows users to manage and rapidly calculate bolt tensioner pressures. The Tentec Bolt Load Software has been designed with the philosophy of minimal input, maximum output. Documentation for multiple bolted joint projects can be created very quickly with minimal operator input. The software package contains data for the following standard bolted flanges.

  • ANSI B16.5
  • MSS SP- 44
  • API 6A
  • API 17SV
  • SPO/Norsok L- 005
  • Vector SPO Compact Flanges
