API 1104 sets the welding and inspection acceptance standard for new-construction pipeline work. Prime Inspections built its reputation on field radiography — putting certified crews and cameras on the girth weld as pipe goes into the ditch, so the quality record keeps pace with construction instead of trailing behind it.
Our Level II and Level III technicians shoot RT and digital DR on mainline welds and tie-ins, with AUT available where a qualified procedure calls for it, delivering same-shift interpretable results and documentation that stands up to owner and third-party review.
Certified Level II and Level III technicians, methods qualified to API 1104 acceptance criteria.
Field RT and digital radiography on mainline girth welds as pipe is strung, welded, and lowered into the ditch.
Radiographic and AUT inspection on tie-in welds, launcher/receiver piping, and above-ground station connections.
Inspection support during procedure and welder qualification testing to confirm welds meet API 1104 acceptance before production welding begins.
RT and DR re-inspection of repair welds to confirm the defect was removed and the repair meets code before backfill.
Prime's crews built their reputation on field radiography — reading a weld right the first time, on schedule, in the ditch.
Digital radiography delivers same-shift results so the crew isn't waiting on film development to keep moving down the spread.
Level II and Level III technicians holding ASNT and AWS certifications, deeply experienced in API 1104 acceptance criteria.
Nationwide coverage across 11 locations, mobilized to keep pace with new-construction schedules.
Prime covers the full method and industry range beyond API 1104 new construction.
Girth weld radiography and phased array UT for pipeline construction and integrity programs.
Turnaround and shutdown inspection for refinery and petrochemical process piping and vessels.
Single-scan weld imaging and corrosion mapping with PAUT and AUT.
Conventional RT, digital radiography (DR), computed radiography (CR), and real-time radiography (RTR).
NDT for hyperscale, colocation, and AI data center mechanical and structural systems.
Cryogenic-rated inspection for LNG liquefaction, regasification, and export terminals.
API 1104 is the standard for welding pipelines and related facilities, covering both welding procedures and the acceptance criteria for weld inspection — the governing code for most new-construction pipeline welding in the US.
Radiographic testing (RT/DR) is the traditional method; API 1104 also permits AUT (automated ultrasonic testing) as an alternative to radiography when performed to a qualified procedure. We provide both, matched to your project spec.
Yes — Prime's crews shoot girth welds in the field as pipe goes into the ditch, delivering same-shift interpretable results so construction isn't waiting on film turnaround.
