PureEM - Electromagnetic Inspection Technology for Concrete Pressure Pipe by Pure Technologies - a Xylem brand. PureEM is an electromagnetic (EM) inspection technology for evaluating the current condition of Prestressed Concrete Cylinder Pipe (PCCP).

Electromagnetic inspection of prestressed concrete pressure pipe. Denver, CO: AWWA Research Foundation and American Water Works Association, © (OCoLC) Document Type: Book: All Authors / Contributors: Brian Mergelas; Xiangjie Kong; AWWA Research Foundation.; American Water Works Association.

A new electromagnetic technique for inspecting prestressed concrete pressure pipe (CPP) for broken prestressing wires is described. CPP is used for water supply lines, power station cooling loops and waste water force lines.

The smaller lined Cited by: 3. A new electromagnetic technique for inspecting prestressed concrete pressure pipe enables nonintrusive inspection for even single broken prestressing wires. Prestressed concrete pressure pipe (CPP) is in widespread use throughout Canada and the United States, with a total of s mi (30, km) of pipe in use in North America's major Cited by: 7.

A new electromagnetic technique for inspecting prestressed concrete pressure pipe (CPP) for broken prestressing wires is described.

CPP is used for water supply lines, power station cooling loops. A pressure pipe will typically rupture when a finite number of prestressing wires is broken along the pipe length.

Individual distressed pipe pieces with broken wires may be identified through an internal inspection, such as visual inspection, sounding, electromagnetic inspection, or others. A new electromagnetic technique for inspecting prestressed concrete pressure pipe (CPP) for broken prestressing wires is described.

CPP is used for water supply lines, power station cooling loops and waste water force lines. The smaller lined cylinder pipes have diameters mm. They have a thin steel cylinder with an inner centrifugally cast concrete core mm thick. Prestressed Concrete Pressure Pipe, Steel-cylinder Type (AWWA C) Lined-cylinder Pipe (LCP).

First used in North America inLCP consists of a welded steel cylinder with steel joint rings at each end, an internal concrete lining, high-tensile strength steel wire wrapped directly on the steel cylinder and an external coating of Portland.

Prestressed concrete pressure pipe (CPP) is in widespread use throughout Canada and the United States, with a total of s mi (30, km) of pipe in use in North America's major water. Uses of Prestressed Concrete Pipes.

Prestressed concrete pipes are used for many purposes as follows: To supply water for domestic needs, where water needs high pressure to supply uniformly to distributed mains. For Industrial purposes such as re-circulating pipes, cooling water pipe lines etc.

Used as Pipe lines which carry sewage using gravity. Denver Water's Conduit No. 94 consists of cm (72inch) and cm (inch) diameter prestressed concrete embedded cylinder pressure pipe (PCCP).

The PCCP conduit extends from the Moffat Treatment Plant located in Lakewood, Colorado a distance of approximately km ( miles) to 56 th Avenue and Washington Street in Adams County. Sincewe have been providing inspection and condition assessment to Phoenix’s inch and larger prestressed concrete cylinder pipe (PCCP) water mains.

Through this program, we’ve inspected 22 distinct projects or scenarios, totaling over 57 miles of transmission pipeline. Prestressed concrete pressure pipe may range in diameter from mm to over 5 m. In case of a failure, the potential for loss of property and/or life increases with pipe diameter and location.

Diameters over m tend to be manufactured as embedded cylinder pipes. PCCP is a composite pipe structure made up of a concrete core and a thin steel cylinder, compressed using high-tensile-strength prestressed wires and protected with a mortar coating.

These pipes carry high internal pressures and external loads and. Electromagnetic Inspection of Prestressed Concrete Pipe. Date Published. Mar 1, Electromagnetic Inspection of Prestressed Concrete Pressure Pipe.

Nondestructively evaluates the integrity of concrete pressure pipe by detecting broken prestressing wires using the remote field eddy current inspection technique.

Uses data collected to assist in determining which pipes need to be repaired or replaced. Published in   Their technical paper reported that, based on the electromagnetic and acoustic inspections ofpipe sections (about million feet), only % had electromagnetic signatures consistent with prestressing wire break damage.

In addition to L and E prestressed concrete pressure pipe (PCCP) in seven sizes ranging from 42 inches. As the pipe material specifics were still unknown at the time of the inspection, the Pure elected to conduct a PipeDiver run to accommodate both possible types of pipe material – assumed by all to be bar wrapped pipe (BWP) and prestressed concrete cylinder pipe (PCCP).

Force main defects can vary from one pipe material to another.
