Tubular Department



Experienced MACHINE OPERATORS perform threading of all Benoit® Premium Tubing Connections on state-of-the-art Computer Numerically Controlled lathes. Precision ground machining & threading inserts are QC inspected prior to use in the manufacturing process. This attention to detail guarantees the thread accuracy & sealing performance of each connection manufactured at Benoit®.
 

INSPECTION of each & every connection is performed by a full time Quality Control Specialist. Our QC Specialists report directly to the Quality Assurance Manager and operate independently of the Production Department. Thread inspection includes control of the geometry of the sealing shoulders, thread height, crest & root diameters. Final acceptance of all products rests with the Quality Control process. Connections that do not meet quality standards are marked for reprocessing.
 

ZINC-PHOSPHATE COATING is a chemical coating process applied to the threaded connection of Carbon Steel tubing. This special coating process gives the threaded area maximum protection against corrosion & galling.
 

END BLASTING is performed on the threaded & sealing surfaces of all Special Alloy tubing, followed by application of a coating of Dry Moly. This process establishes the connection surface properties to minimize galling.
 

FINAL INSPECTION / APPLICATION OF THREAD STORAGE COMPOUND & THREAD PROTECTORS is the final process prior to storage. Each length is final inspected. Connections are coated with a rust preventative lubricant & then fitted with a thread protector to prevent damage during shipping.
 

BENOIT® maintains a documented training program. All personnel receive SOP indoctrination, plus on-the-job training & classroom instruction. Our training program is controlled via computerized database program to ensure that personnel are always up-to-date on new or revised procedures.
 

All tubing is moved on the yard with Forklifts fitted with padded forks for moving SPECIAL ALLOY tubing. In addition, tubing is moved to threading in a special cradle that eliminates bundling, & all rack systems are wood or rubber padded to prevent pipe damage. Personnel are trained in accordance with documented Special Alloy handling procedures.
 

BOLSTERING of Special Alloy tubing is available. This practice minimizes potentially damaging joint to joint contact during shipping.
