Services Offered

Boiler Inspection

Our lead boiler inspectors have over 20 years of experience inspecting various types of boilers from recovery, fluidized bed boilers, hog fuel and power boilers. To learn more about our boiler inspection service, click here.

 

Generating Bank Inspection

5 Star offers remote field inspection for the generating bank. It is used for detecting and measuring volumetric wall loss from erosion and corrosion. Remote field is a good alternative to IRIS to use on generating banks when time or budget constrictions are impacting the outage/shutdown. Remote field testing eliminates the headaches of plugging tubes or modifying water side lock out to fill generating bank tubes with water, and can be performed in a shorter amount of time than IRIS.

Weld Inspection 

5 Star offers American Welding Society (AWS) certified welding inspectors (CWI’s) and phased array inspection for outage support. Whether from steam line inspections to boiler component overhaul, your covered. We have the experience from handling small outages to major overhauls. To learn more about our CWI’s, click here.

Quality Control – Quality Assurance

QC/QA is a crucial component to overhauls/shutdowns. It’s important to make sure that proper materials and parts are being installed. Our QC/ QA inspectors are entrusted for high quality and reliable inspections that comply with the requirements of the controlling jurisdiction, applicable governing code, customer requirements, and applicable standards of 5 Star Testing, Inc. This will ensure that you receive the quality of work that is expected from your contractors. To learn more about our QC/ QA services, click here.

 

Steam-line Inspection 

Maintaining a proper steam line is critical to safety and operation of a plant. 5 Star offer a complete steam line inspection that includes taking hanger measurements, hanger attachment inspection, ultrasonic thickness measurements, phased array examination of weld joints, hardness testing, and metallographic replications.

 

Piping Inspection 

5 Star offers numerous piping inspections, from coal piping too flow assisted corrosion (FAC) inspection. This is commonly performed on piping elbows & tees. You will typically see corrosion or erosion in these areas. These are critical components from a safety & operational stand point. Repeat inspections can help understand corrosion / erosion rate, and prepare ahead of time for repair and avoid forced shutdowns.

5 Star also provides American Petroleum Institute (API) inspections. To learn more about API 570 Piping Inspections, click here.

 

Air Preheater Inspection

From tubular to regenerative air preheater systems, 5 Star has the experience to help your air preheater run efficiently.  Our inspectors will look for problems such as plugged tubes or baskets, erosion from abrasive flue dust, leakage in casing, and corrosion from dew occurring. Our inspectors will recommend repairs and/or use of different materials as needed.

 

Duct Work & Stack Inspection

Proper maintenance of the duct work can help improve efficiency of your boiler. Our inspectors will mark out areas for repair, detail them in a work order along with photos for the maintenance contractor to follow.

Stack Inspections can be performed by a man-lift basket. When performing the inspection by man-lift basket, our inspectors are able to get an up-close visual inspection, and even taken ultrasonic thickness readings if necessary. Via the man-lift basket they are able to inspect the inside and outside of the stack for corrosion, degradation, and other damage.

 

Deaerator (DA) Tank & Heater Inspection

Deaerator tank and heater inspection consists of a visual inspection of the inside and outside of the tank. Our inspectors will look for problems like flow assisted corrosion (FAC) on the shell of the tank, around nozzles, grating, etc. A general ultrasonic thickness survey of the tank will be performed, along additional testing as needed to define any wastage areas. Magnetic particle inspection will be performed on welds to identify any cracking issues, based on the visual inspection or a pre-defined scope.

 

Condenser Inspection

Our visual inspectors will look over the waterbox, tubesheet, hotwell, tube bundles, and structural components. They will inspect for erosion, corrosion, cracks, blockage, leakage, foreign material, bends and warped pieces. When components like spargers fail it can lead to further damage occurring on structural beams and the tube bundles.

 

Paper Machine Inspection

5 Star offers a comprehensive paper machine inspection to TAPPI standards. We have equipment such as the hartford wedge that will go across the outside of the dryer can to take thickness measurements, the equipment can adjust for the velocity to match the acoustic properties of the cast dryer can. NDT technicians will use ultrasonic testing instruments to inspect for cracked bolts. Our internal inspections is where our technicians will inspect for grooving in the shell, condition of spoiler bars, siphon tubes, counter weights, etc.

 

Digester & Accumulators Inspection 

Proper inspection of disgesters and accumulators can help avoid costly forced shutdowns. 5 Star Testing offers complete internal & external inspections. We have advanced phased array equipment to scan the outside of the shell for corrosion & worm-holing. Our equipment can detect worm-holing at inception stages, helping you to plan ahead for repairs.

Storage Tanks, Pipelines, and Pressure Vessels

5 Star Testing offers American Petroleum Institute certified inspectors for storage tanks, pipelines and pressure vessels. They can perform code calculations to help determine inspection intervals & life expectancy of the tank. To learn more about our API services, click on the following links.

 

Heat Exchangers 

5 Star offers tubular eddy current inspection for heat exchanges. This non-destructive testing (NDT) method is ideal for non-ferromagnetic tubing. To learn more about eddy current inspection, click here.
