Nexus Integrity Management, LLC not only has the ability to maintain client assets with seamless cathodic protection installations, but has the capability to conduct many cathodic protection surveys as well as over-the-top asset mapping simultaneously. Nexus’ unique ability to maximize this service saves clients time and money in the long-run when compared to normal operating procedures. Nexus puts to work some of the industry’s leading cathodic protection equipment and mapping software. After successfully conducting a cathodic protection survey and the asset is accurately mapped, Nexus thoroughly looks at the data and if requested by the client, proposes recommendations as well as a plan of action to correct any inadequacies with the asset.

Equipment
For Nexus Integrity Management, LLC mobilization is one of the keys to keeping projects on schedule and on budget. Equipment bought or rented by Nexus has regularly scheduled maintenance and is cleaned each day after use. For cathodic protection survey and asset mapping Nexus uses equipment from companies that has durability as well as functionality.
Leak Detection
Nexus Integrity Management, LLC combustible gas leak detection surveys are completed by using state-of-the-art flame ionization and hydrocarbon leak detection equipment. Nexus’ professional technicians have certification and training for leak detection surveys in both urban and rural areas. Nexus has the ability to conduct leak detection surveys on all classifications of buried pipelines. These pipelines transport hydrocarbons such as natural gas, propane, ethane, propylene, acetylene, LPG, or liquids that gasify as soon as in the atmosphere, such as ammonia and hydrogen. Nexus follows strict procedures when conducting leak detection surveys. These procedures involve the technicians electronically locating every pipeline, wherever necessary, to ensure the leak detection survey is accurately conducted over-the-top of the pipeline; consequently detecting all potential leaks.
Scheduled leak detection surveys of gas transmission lines are the best method of protecting the lives of people who live and work near them. For that reason, the DOT included several regulations that call for intermittent surveys depending on area population and the content of the transmission line.
DOT Classifications
Class 1
Any location that has 10 or fewer buildings intended for human occupancy.
Class 2
Any location that has more than 10 but fewer than 46 buildings intended for human occupancy.
Class 3
Any location that has 46 or more buildings intended for human occupancy; or an area where the pipeline lies within 100 yards (91 meters) of either a building or a small, well-defined outside area that is occupied by 20 or more persons on at least 5 days a week for 10 weeks in any 12-month period.
Class 4
Any location where buildings with four or more stories above ground are prevalent.
Equipment
Nexus Integrity Management, LLC is able to complete any distance amount of leak detection survey for a client’s specific needs or time restraints. The equipment Nexus uses allows for technician’s to thoroughly and accurately conduct leak detection surveys quickly and safely. Nexus utilizes 4×4 ATVs equipped with specific modifications for remote right-of-way access. Nexus uses Heath Consultants DP 4 Ionization Gas Leak Detector, which is one of the leading leak detectors in the industry. The DP 4 utilizes Flame Ionization Technology, this well-known and field proven principle to measure very small concentrations of hydrocarbons. A controlled amount of fuel is mixed with a sample and burned. When hydrocarbons are present in the sample, ionization occurs. The amount of ionization is electrically measured and converted to a visual indication of hydrocarbon level in PPM via the instrument’s meter.
Training
Nexus Integrity Management, LLC provides training using the same LDS equipment that the technicians in the field use. Technicians will teach the steps involved in accurately pinpointing underground gas leaks as well as how to properly use the equipment in any situation. Identifying a leak is the most time consuming, inefficient and costly portion of leak management control. Nexus’ training is designed to make the pinpointing process safer, more efficient and help reduce costly mistakes in the field.
