HMT can also assist you in meeting the require-
ments of SPCC for tank integrity testing. HMT
Inspection places a high priority on reporting.
The field inspection data obtained, and the
engineering analysis and evaluation work
performed must be translated into the proper
report format.
HMT emphasizes prompt turnaround and
quality reporting. The reports are “user
friendly”with a Management Summary section
containing concise data presented in an
understandable manner. In addition to these
standard reports, HMT prepares many different
types of reports, depending upon the nature
of the project. These reports address such
topics as Integrity Testing, Suitability-for-
Service Evaluation,Verticality Studies, Seal
Inspections, Foundation Settlement, Seismic
Evaluations, Repair Recommendations, and
Post Repair inspections.
Contact your local HMT representative to
discuss the full suite of products and services
that will satisfy all your inspection needs.
HMT Inspection offers a complete line of
NDE services and engineering evaluations
per API Standard 653, API Standard 570, API
Standard 510 and STI Standard SP001 based
on data gathered from the field inspections.
The proper standard is then applied and
recommendations are presented. Our certified
inspectors and engineers work as a team to
provide quality, comprehensive inspections
and recommendations in a safe, reliable,
efficient manner.
Inspectors are certified per ASNT SNT TC-1-
A (Level I, II, and III), for a large array of NDE
techniques including ultrasonic,magnetic
particle, liquid penetrant, visual, vacuum box
testing, helium leak testing, and other NDE
methods and techniques.
HMT Inspection provides certified inspectors
to meet either API or STI Standard SPOO1(for
Shop Built Tanks) inspection standard,
including tank evaluation, inspection findings,
repair recommendations and post repair
services in a safe, reliable and efficient manner.
Inspection Service
Other Inspection Servicesprovided by HMT Include:
• Engineering Services
HMT’s Engineering services could include
settlement evaluations, corrosion rate
calculations, safe fill height calculations,
seismic evaluation, brittle fracture
evaluations,maximum working pressure and
other evaluations referenced in the various
standards. Other engineering services
include fitness for service evaluations and
inspections per various state environmental
regulations. We also perform specialized
evaluations such as out-of-roundness surveys
and verticality evaluations.
• Alternating Current Field
Measurement (ACFM) Inspection
ACFM is a non-contact technique to detect
and size surface breaking crack-like defects
through coatings up to a thickness of 0.200
inch. HMT has used this method to detect
crack-like defects in tank shell-to-bottom
welds, tank bottom lap welds, sumps,
nozzle and appurtenance welds, and Stress
Corrosion Cracking (SCC) in ethanol service.
Surface preparation is reduced compared
to other NDE techniques.
• Helium Testing / Mass
Spectrometer Leak Testing (MSLT)
HMT’s Helium leak testing program is a
proven, very effective method for the
detection of leaks in many petrochemical
applications, including tank bottoms,
roof pontoons, roof drain systems and
heat exchangers.
• Piping Inspection
HMT’s piping inspection program includes
MFL Pipe Scan services, which provides near
100% inspection coverage for aboveground
un-insulated straight runs of piping and
vessels up to 0.750 inch wall thickness. Our
API 570 inspections and engineering
evaluations provide NDE data, visual
inspection, and engineering assessments that
include Maximum Allowable Working
Pressure (MAWP) and remaining service \
life calculations.
• Low Pressure Storage Spheres/
Pressure Vessels
HMT’s vessel inspection program includes a
full line of NDE inspection services for low-
pressure storage spheres, pressure vessels
and bullet tanks, including a staff of
experienced API 510 inspectors. HMT’s
services include an automated ultrasonic
crawler and MFL wallscan.
