OCTG & Drilling Tubulars

 

Benor offers a full range of services in connection with inspection and preservation of OCTG tubulars and drilling equipment.

 

OCTG Inspection

 

Benor provides OCTG inspection in accordance with API or customer specified requirements.

We can offer the following OCTG services:

  • Automated ultrajetting up to 2800bar for cleaning and removing coating down to bare metal

  • Cleaning of threads, internal bore and protectors

  • Visual thread inspection (VTI)

  • Visual inspection of ID and OD of tube. Polish/grinding of tong marks on OD and ultrasonic wall thickness measurements

  • Full length drifting with API drift mandrels, or as specified by customer

  • Traceability check; recording of pipe identification numbers

  • Tally, length, and ID measurements

  • Preservation of connections with running or storage compound and assembly of protectors

Drill Pipe and BHA Inspection

 

Benor offer drillpipe and BHA inspection in accordance with NS-2, DS-1 and API standards.

Our services regarding drillpipe, BHA and additional drilling equipment are:

  • Ultrajetting up to 1400bar on external surfaces, and 1000bar on internal surfaces

  • Dimensional control and visual inspection of tube and connections

  • White contrast and fluorescent MPI

  • LPI of non-mag tools

  • End area UT inspection (UTEA) on drillpipe upset areas

  • Ultrasonic wall thickness measurements

  • Electromagnetic inspection (EMI) of drillpipe tubes from 3" to 6 5/8" OD

  • Preservation of connections with running or storage compound

OCTG Preservation

 

We offer anti corrosive preservation of internal and external surfaces on OCTG tubulars. A option that will extend the lifetime of customers' OCTG tubulars, especially when preparing pipes for backload/ long time storage.

Water Blasting up to 2800bar

 

At our tubular inspection facility on Vestbase in Kristiansund, we can offer ultrajetting up to 2800bar. Ideal for removing mud, scale, dirt and even coating on tubulars up to 16" OD, without any use of chemicals.

Video Inspection

 

Visual inspection inside pipes and pipelines, to determine the condition of the internal surface.

Results are presented in a visual report with customers' acceptance criteria and a conclusion.

On request the inspection can be supplied on DVD.

Visual inspection, with or without optical aids, is the original method of NDT. Many defects are visible at the surface and can be detected by careful visual scrutiny.

Optical aids include low-power magnifiers, microscopes, telescopes and also specialised devices such as boroscopes, endoscopes and other fibre-optic devices for the inspection of restricted access areas. These devices can also be used with television camera systems. Much of the success of visual inspection depends on the surface condition and the lighting arrangements. Surface preparation such as cleaning and etching is often used, and also surface replicas can be taken for both macro and microscopic examination. In-situ metallography is also possible.

EMI Scanning

 

Benor offers Electromagnetic Inspection (EMI) scanning on drillpipes and tubulars, from 3" to 6 5/8" OD. In accordance with NS-2, DS-1 and API standards. At our tubular inspection facility in Kristiansund we have a fixed EMI unit, and in Hammerfest we offer EMI scanning with our mobile buggy unit. Both with wall thickness scanners.
