Perforating gun carrier pipes for oil and gas wells
Perforation gun carrier pipe is used to produce perforating guns run in oil and gas wells. CNPS notes that various gun types can be produced, including conventional guns and horizontal-well guns, so the carrier pipe must hold dimensional precision and toughness through charge detonation and retrieval.
Existing features listed for this product include good dimensional precision (OD tolerance ≤ ±0.5%, WT tolerance ≤ ±0.8%, tortuosity ≤ 1 mm/m), rational strength and toughness matching (swelling ratio ≤ 5 mm, burr height ≤ 5 mm), and long-term stability of physical dimension and performance. A company standard reference QCBQB 232-2013 appears in the current copy. Keep those published figures as the on-page baseline and confirm inspection criteria for your gun design.
Buyers typically align carrier OD, wall thickness, steel grade, and phasing holes to the gun system and well trajectory. Share your gun drawing or bill of materials so CNPS can match pipe supply to the perforating program.
Key applications
- Conventional perforating gun carriers
- Horizontal-well perforating gun carriers
- Other perforating gun pipe programs (confirm type)
What to confirm with CNPS
- Size / rating / medium / standards you need (OD, WT, grade, QCBQB or project spec)
- Gun type (conventional, horizontal, other) and hole pattern
- Inspection, marking, and packaging requirements
