Hydrostatic Cylinder Testing
DOT regulations require periodic hydrostatic testing of high-pressure cylinders. For instance, high pressure cylinders need a hydrostatic test every 5 or 10 years depending on its markings. The purpose of hydrostatic testing is to examine the structural integrity of the cylinder by pressurizing the cylinder to its designed test pressure. If the cylinder passes the test, it can be filled and put back into service until the next test date.
Fire King is a DOT-approved high- and low-pressure hydro testing facility located in the Duwamish industrial area of Seattle, Washington. This centralized location allows us to serve the Greater Puget Sound Region and beyond. As one of the largest independent hydrostatic testing facilities in the Pacific Northwest, we are adequately equipped to handle bulk orders.
Cylindrical structures, including pipes and pressure vessels, must be defect-free to remain dependable and safe. Ultrasonic Examination (UE) testing uses ultrasound technology to measure flaws, defects, and wall thickness in steel high-pressure compressed gas cylinders. This is an effective way to test a cylinder’s overall safety and structural integrity. Fire King is certified to perform UE testing at our Seattle facility.
Other Cylinder Testing Services
In addition to hydrostatic and UE testing, Fire King offers these additional cylinder testing services:
- Propane requalification: Propane cylinders require retesting, known as requalification, every 5 or 10 years depending on the cylinder type, condition, and prior requalification method. Cylinders must also undergo a visual inspection before each refill to ensure there is no rust, corrosion, external damage, missing parts, or defective valves.
- Eddy current testing: SCBA and SCUBA cylinders require eddy current testing in accordance with the manufacturer’s instructions. As long as the cylinder passes the test, it can be hydrotested and returned to service. However, as soon as cracks become evident during testing, the cylinder must be retired.
We recondition high-pressure compressed gas cylinders to conserve resources and save you money. Our techniques allow used fire extinguishers, oxygen tanks, SCUBA gear, and more to remain in use for decades.
We remove any labels, shot blast the surface, and apply new paint to make the used cylinder look like new. We thoroughly test all reconditioned cylinders to ensure they meet performance standards. In the end, you receive a cylinder that looks and performs like new for a fraction of the cost.
Our maintenance and reconditioning services include:
- Cosmetic exterior blasting and painting
- Internal shot blasting
- Neck ring replacement
- And more
