QSA Global, Inc. provides Type A storage and shipping containers or we can load and ship sealed sources in your supplied Type A containers.
We also provide rugged field containers for all sealed radioactive sources.
QSA Global, Inc. manufactures insoluble Cs-137 fused glass sources. We also offer the option for magnetic bull plugs to facilitate downhole retrieval.
Yes, we offer disposition services for old or unwanted radioactive sources.
QSA Global, Inc.'s oil well logging sealed radioactive sources are manufactured with superior materials, such as MP35N high performance alloy for outstanding durability, corrosion resistance, and extremely high tensile strength. We can also manufacture sources capsules from 17-4 PH stainless steel offering magnetic properties along with high strength and corrosion resistance. All our sealed radioactive sources are tested according to ISO 2919/ANSI N43.6 standards. We perform high-pressure testing to 60,000 PSI (413.7 MPa), which is well beyond the class 6 required specification of 3.6-24.7 PSI (25 kPa-170 MPa) and temperature test to the maximum class 6 specification of 800o C for 1 hour. The following are just a few of the tests we perform:
ISO 2919 Class 6 Puncture Test: 2.2 lbs (1 kg) from 3.3 ft (1 m) or equivalent imparted energy
ISO 2919 Thermal Shock Test: 20o C using liquid nitrogen
Post-thermal shock test with nitrogen
ISO 2919 Temperature Test: 800° C (1 hr)
Water quench test
After the water quench test
Our multi-disciplined technical experts are here to help you find the right Oil Well Logging sealed radioactive sources to achieve fast, precise measurements in your Wireline and Measurement While Drilling (MWD or LWD) applications.
