Cracked Cast Iron Pipes In Office Buildings VERIFIED

A flexible, epoxy-saturated liner is inserted in one end of the pipeline and threaded through to the other end. It is gently inflated to full pipe diameter and cured (hardened), creating a new structural line within the old cast iron pipes.

Trenchless pipe lining is appropriate for lateral and vertical pipes, sewer, and drainage (rainwater leader) lines. It can be used in single-family homes, multi-unit homes, condos, businesses, commercial/industrial buildings, and more. Our lining product has a 50-year life use expectancy.

Since the early 1800s, cast iron pipe has been manufactured in the United States to assist in water distribution and eventually wastewater disposal. Then, as early as the 1890s, cast iron soil pipes grew into an industry where the majority of homes and commercial buildings constructed utilized this method to build their sewage pipe systems.

While there were certainly other materials and methods used to formulate sewage piping, cast iron pipe had proven to be the most durable and reliable method of piping due to the length of time that the materials lasted.

Unfortunately, homes, commercial buildings, and condominiums constructed during the time period where cast iron pipe was the material of choice are now facing serious sewage problems. As the cast iron pipe ages, the horizontal base literally begins to disappear (channel) due to years of water flow along the ferrous cast iron pipe. When the pipe channeling exposes the soil underneath the pipe, causing a leak, soil erosion takes place and the drainage system is greatly compromised.

Pipelining Technologies, Inc. specializes in trenchless cast iron pipe repair. Our pipe lining solution is the most effective, efficient, and least-invasive way to reverse the negative effects of cast iron piping. Using a structural liner, we essentially create a new pipe within the old cast iron pipe.

Although cast iron piping has a general lifespan of 25 to 30 years, pipe failure can happen at any time and come in a variety of forms, but the bottom line is that those buildings constructed using cast iron pipes need repair and they need it fast.

Trenchless sewer repair eliminates the need for large-scale destruction of floors and landscaped areas to conventionally replace the damaged pipes, the costs associated with replacing those surfaces, and limits the exposure to health and environmental risks created by major sewer excavations.

Generally, your private sewer main, or lateral, becomes the responsibility of the city at the tap to the city sewer. Blockages and backups in the city sewer system can cause backups on private property, so identifying the location of the blockage is very important as it relates to responsibility.\n","@type":"Question","name":"How long does it usually take to do a trenchless sewer repair job?","acceptedAnswer":"@type":"Answer","text":"In residential homes, a good rule of thumb is \u201cone liner per day.\u201d For example, if your home has a building main, two bathrooms, a kitchen and a laundry, that is five individual liners, hence five days of work. On large-scale commercial or high-rise condominium projects, more aggressive timelines are typical, with anywhere from two to four liner installations a day.\n","@type":"Question","name":"Is there a warranty on the work that is done and the materials?","acceptedAnswer":"@type":"Answer","text":"Pipelining Technologies offers a full five (5) year parts AND labor warranty on every pipe lining job. This is four years more than a conventional Plumber\u2019s one-year warranty and pipe lining carries a transferrable minimum fifty (50) year life-use expectancy.\n","@type":"Question","name":"Would we have to leave the home or business while the work is being done?","acceptedAnswer":"@type":"Answer","text":"No. Pipelining Technologies works to stagger brief water shutoffs in a way that residential customers will have some facilities to use each day of the project. Since pipe lining can be performed in a much shorter timeframe than pipe replacement, there are typically only a few days of slight inconvenience in comparison to several weeks of water shut off with conventional pipe replacement.\n","@type":"Question","name":"Does trenchless sewer repair work on tall buildings such as apartments or condominiums?","acceptedAnswer":"@type":"Answer","text":"Lining of vertical stacks in high-rise buildings is amongst the most cost effective and time saving applications of trenchless pipe lining, also known as CIPP, cured-in-place pipe. Conventional replacement of a vertical stack on a building of significant height can take weeks, even months to complete, and the residents are without water to the affected facilities for the entire time. Pipe lining can accomplish the same job in two days by lining from the roof continuously to the underground with little to no need to enter individual units.\n"]}Serving Saint Lucie CountyPipelining Technologies, Inc. serves the Saint Lucie County, Florida area, providing trenchless sewer pipelining services. Here are some of the cities we serve:

In the first report, you can rank states by either gas distribution main miles or service line counts. Distribution mains are natural gas distribution pipelines that serve as a common source of supply for more than one service line. Service lines are the pipelines that transport gas to a customer's meter or piping. The table is initially sorted by the number of miles of cast or wrought iron gas distribution main, but can be sorted by any of the columns.

The second report shows the change in main miles and service line counts over the years. Nationally, cast and wrought iron distribution main mileage has decreased by 50 percent from 2005 to 2020. The number of cast or wrought iron service lines has decreased by approximately 80 percent over the same time period. The third report shows data for each operator reporting iron pipelines since 2005.

All of the reports can be limited to a single state by using the state prompt at the top. Any state not included in the drop-down either never had cast and wrought gas distribution pipelines or all were removed before 2005. 24 States and 1 territory have completely eliminated cast and wrought iron gas distribution pipelines: AK, AZ, AR, CO, GA, HI, IA, ID, KS, MN, MT, NM, NC, ND, NV, OK, OR, PR, SC, SD, UT, VT, WA, WI, and WY.

Even though the amount of cast iron pipelines is declining, there have been a number of recent incidents caused by cast iron gas distribution main failures, resurging attention to the risks associated with cast and wrought iron pipelines.

What Causes Iron Pipe Leaks?The biggest threat to cast or wrought iron pipe is earth movement. If these pipelines are disturbed by digging, seasonal frost heave, or changes in ground water levels, leakage may occur.

When leaks occur on low-pressure systems with cast or wrought iron distribution lines, the volume of gas escaping through the failure point is much less than what might escape through the same size failure in a system operating at higher pressures. However, even a relatively small volume of natural gas leakage can have catastrophic consequences.

HistoryCast and wrought iron pipelines were originally constructed to transport manufactured gas beginning in the 1870s and 1880s, with cast iron becoming more popular in the early 1900s.

In 1970 PHMSA began collecting data about gas pipelines mileage categorized by pipe material type. In 1983, gas distribution pipeline operators reported 61,536 miles of cast iron and 4,371 miles of wrought iron pipe. Operators began submitting merged data for the two beginning in 1984.

Wrought iron pipelines were joined end-to-end using either threaded or compression couplings, while cast iron pipelines were linked using bell and spigot joints with packing material stuffed in the bell to form a gas tight seal. Since these pipelines transported wet, manufactured gas, the packing material absorbed moisture and generally did not leak.

Specifically for cast/wrought iron, operators must have knowledge of the specific characteristics of the pipe and environments where graphitization could be severe. Evaluating past leak history and monitoring cast/wrought iron pipe during excavations are also key components of maintaining integrity.

In 1986, the NTSB investigated an explosion at a restaurant in Derby, Conn., that killed six people and injured 12. The NTSB issued recommendations for corrective action only to the pipeline operator. In 1990, a natural gas explosion and fire killed one person, injured nine, destroyed two homes, and damaged two adjacent houses in Allentown, Pa. The NTSB report found that a water main leak eroded support under a 4-inch cast iron gas main. This ground disturbance results in a circumferential crack in the gas main. Natural gas migrated through the soil and into the basement of one of the homes where it ignited, exploded, and burned. The cast iron gas main was significantly weakened by graphitization.

RSPA Alert Notice 91-02 Encourages operators to develop procedures to identify segments of cast iron pipe that may need replacement. Reminds operators that pipeline safety regulations require generally graphitized cast iron pipe to be replaced and protect excavated cast iron pipe from damage.

RSPA Alert Notice 92-02 Reminds operators that pipeline safety regulations require operators to have a procedure for continuing surveillance of pipeline facilities to identify problems and take appropriate action concerning failures, leakage history, corrosion, and other unusual operating and maintenance conditions. This procedure should also include surveillance of cast iron to identify problems and take appropriate action concerning graphitization. 350c69d7ab
