amosco : services : drill pipe & hevi-wate drill pipe

Depending on your requirements, AMOSCO is able to provide a variety of Drill Pipe related services ranging from the Basic/Standard Maintenance Drill Pipe Services to the more critical inspection services. AMOSCO is a Member of The International Pipe Inspectors Association (IPIA).

STANDARD DRILL PIPE SERVICES
SERVICE	DESCRIPTION
VISUAL BODY INSPECTION	A thorough visual inspection of possible noticeable external damages inflicted is performed; most damages encountered arise from handling of the casing, such as major dents and mashes. Other types of flags will be external corrosion, laps, and straightness.
VISUAL THREAD INSPECTION (VTI)	Both pin and box ends are thoroughly cleaned and visually evaluated for any damages, such as dents, corrosion, galled threads, etc.
ELECTROMAGNETIC INSPECTION (EMI)	Using a specialized Electromagnetic unit, detection of transverse or 3-dimensional defects can be located.
REFACING	Seals found to be damaged or corroded are refaced to the limitation of API RP-7G.

OPTIONAL DRILL PIPE MAINTENANCE SERVICES
SERVICE	DESCRIPTION
HARDBANDING	In order to protect the clients drill pipe tool joints and center wear pads from excessive wear while drilling in abrasive environments, hardbanding is applied in 1 inch bands around the circumference of the tool joints and center wear pads. Various mesh sizes of tungsten can be applied with the band. As an alternative to tungsten, Amosco is also capable of applying Pinnacle Pinnchrome and Arnco 200XT. The application reduces casing wear while protecting the tool joint of the drill pipe.
BUILD-UP	Controlled automatic welding procedures are used to build-up the outside diameter of worn tool joints to their original size. Instead of scrapping drill pipe whose tool joint OD's are below specification, applying the same concept as hardbanding is able to literally reconstruct the OD of your tool joints back to specification, thus salvaging the premium pipe body and saving the client money.
STRAIGHTENING	Bent pipe is straightened using a ram-type, hydraulic press.
CLEANING (Internal / External)	Wire brushing or Rattling to remove rust, scale and other debris.
COATING (Internal / External)	A thin rust preventative coating is applied internally or externally to maintain the integrity of the casing.
MILL SLOTTING	Mill slotting is performed by cutting a round or elongated slot into the body or tool joints of drill stem components. In order to cut into and along the pipe, a drill specifically designed for this use is employed. Like the device used for hardness testing, the size and weight of the slotted machine allows our operators to go on-site and perform the job at the clients location. Due to the nature of this service, client specifications are to be followed providing that it does not force the material to fall out of API specifications.

OPTIONAL DRILL PIPE INSPECTION SERVICES
SERVICE	DESCRIPTION
TH HILL DS-1 SERVICES	If the customer's requires DS-1 inspection, AMOSCO can inspect the customer's assets in accordance with TH Hill DS-1 Specifications rather than standard API RP-7G Specifications.
SPECIAL END-AREA INSPECTION	Shearwave ultrasonic inspection is performed on the upsets and friction welded areas of drill pipe. This service is performed to locate fatigue cracks. Inspecting for longitudinally oriented defects and for transverse defects
ULTRASONIC WALL THICKNESS (UT)	Wall thickness is verified by taking random ultrasonic readings or during EMI Inspection to veryify and prove-up areas in question.
API THREAD GAUGING	Using various API gauges, such as thread taper, lead and depth to measure the connection in order to verify the connection is within API Tubing Connection specifications.
