Field inspection techniques for buried steam distribution lines
5 Most Popular Inspection methods. The purpose of this article is to outline 5 popular methods: visual inspection, ultrasonic techniques, radiography, thermography and acoustic emissions. Each of these methods is explained, followed by a qualitative discussion of its implementation. Method 1: Visual Inspection. Leak detection using radiotracer techniques is probably one of the most widespread applications of radiotracers in industrial troubleshooting. Radiotracer techniques are the most competitive for on-line leak inspection of heat exchangers and buried pipelines. Radiotracers help .

Shall provide technical support to the operation of . of transmission and gathering lines. Underground techniques such as boring and horizontal directional drilling (HDD) allow pipe to be installed without digging a trench. HDD is often used where pipe-lines need to make river crossing as a way to greatly reduce the environmental disturbance of the river and to bury the pipeline much deeper.
environments. . In this method, location of the line is detected by the presence of a magnetic field created over the pipe. The detectors manufactured for searching the metal infrastructures may work with various methods. In order to detect the line sought, there must be signals released from one edge of the respective pipe by certain frequency. Underground utilities standards address safety and access rights, selection of the utility, and the continued maintenance of the utility once fiber has been installed. The standards also cover the maintenance and rehabilitation of these systems using robotics technology and chemical grouts, inclusive of guides for application.

Overview As a UT you may have questions about delivering steam from the steam plant to the user. You will find information in this chapter that answer questions about steam distribution systems.

In FYa multi-regional, interdisciplinary team studied the field inspection process and developed further guidance and training resources for inspectors at field stations to.
Steam System Best Practices 14 Best Practices for Guide Lines for Boiler Plant Log Books 1. SCOPE OF BOILER LOGBOOK PROGRAM In all cases, there are minimum tasks and functions for an operator to perform in a boiler plant that is dependent upon the complexity, size and condition of the equipment.
The manager in chargeFile Size: 95KB. Manual Pipeline Inspections (Manual ) is a resource document and tool for the Alberta Energy Regulator (AER) field operations staff. Manual replaces Directive Requirements and Procedures for Pipelines, which has been rescinded.
The application of these techniques and the frequency of application play large roles in risk management and, in fact, are the basis of some regulatory initiatives. Distribution system integrity verification includes pressure testing, acoustic or electrical conductivity testing for reinforced concrete pipe materials, visual inspections, and others.
The role of steam distribution lines is to reliably supply steam of the highest reasonable quality to the steam-using equipment. In order for this to be achieved, condensate must be removed quickly and efficiently through steam traps installed in proper condensate discharge location (CDL) installations.
Some common methods are visual, microscopy, liquid or dye penetrant inspection, mag- netic particle inspection, eddy current testing, x-ray or radiographic test- ing, and ultrasonic testing.
This chapter provides an overview of the in- spection methods that will be covered in the remainder of this book. These inspections are performed as the pipeline is being constructed so gaining access the inspection area is not problem.
In some areas like Alaska, sections of pipeline are left above ground like shown above, but in most areas they get buried. Once the pipe is buried, it is undesirable to dig it up for any reason.
The company also implemented a buried piping and tank inspection program, including the use of improved inspection techniques, such as guided wave technology.
A Novel Acoustic Solution. De Michelis, R. Vario, in Power Plant Life Management and Performance Improvement, Inspection of steam headers and steam lines.
The inspection of steam headers and steam lines is performed by visual, borescope and ultrasonic methods to detect cracks, mostly due to thermal fatigue and originating from the inside surface of header nozzles and penetrations.

In-Line Inspection Technology or “Smart Pigging” Smart Pigging is the practice of using devices known as ILI tools or smart pigs to perform various periodic maintenance inspections usually on a flowing or operating pipeline.
Smart pigs are often long, multi-ton, complex devices consisting of at least four main parts; 1) a. In the buried pipe testing using guided waves the effect of contact with the soil can dramatically increase the difficulty of the analysis.
For this reason it is recommended that only experienced operators are used to test buried pipes. Figure 5 shows a buried pipe at the time of test with the Wavemaker G3. This test was performed from a location.

The sample should be representative of the poles in place. For instance, all the poles on a line or a map section should be inspected as a unit and not just the poles of a certain age group. The inspection of the sample should be complete, consisting of.The tool is placed into the launcher or launching station, it is then driven by the flow of the product, pushing the pig along down the line until it reaches the receiving station.
If a smart pig inspection detects an anomaly, pipeline operators may decide to conduct an integrity dig, which involves excavating a section of buried pipeline.
