HDPE Pipe Fittings – For A Lot Of Industrial Utilities Using HDPE Pipe Fittings.

The qualities of polyethylene pipe are piquing the interest more civil engineers of potable water systems in Canada And America.

The telecommunications and utility industries have long used HDPE pipe fittings to safeguard fiber optic cables and deliver gas, but utilization of the material for h2o systems continues to be trickling slowly toward acceptance in some places.

In Michigan, L . A .-based JM Eagle’s offer to exchange all lead service lines (LSLs) in Flint, where toxic levels of lead leached from damaged pipes, with free PE pipe prompted not simply a study of three sorts of pipe materials – PE, cross-linked PE (PEX) and copper – but a lunch-and-learn session about PE pipe with engineers.

Dustin Langston, an engineer at WL Plastics Corp., which can be operating out of Fort Worth, Texas, said in the telephone interview that his presentation went over the allotted hour without having objections.

“The information was taken well; they had a lot of great questions. It had been a very productive meeting,” he said.

With estimated annual sales of $2.45 billion and yearly pipe sales of $340 million, respectively, JM Eagle and WL Plastics are the first- and 11th-ranked manufacturers of plastic pipe, profiles and tubing in North America, according to Plastics News’ latest ranking. Their overall PE pipe sales are down within the last year because of a forty percent drop in demand through the oil and gas gathering industry, based on the Plastics Pipe Institute (PPI), a trade association situated in Dallas. However, potable applications show big promise as U.S. cities look to find the lead out of their systems and then make some $1 trillion of upgrades over the next twenty five years.

Langston said about 15 people attended the meeting at the Flint office of Rowe Professional Services and some others Skyped in. Rowe handled engineering benefit Flint until June 30 – the city wants to hire a staff engineer now – although the firm will likely be solicited for future work, the town said in the statement.

The presentation dedicated to high density PE pipe and installation methods. Rowe’s engineers’ main knowledge of HDPE to date is employing it for horizontal directional drilling (HDD) under rivers, Langston said, adding he got plenty of wide eyes when he described cellular phone approach to pipe bursting. Few of the attendees had heard about the technology before.

A trenchless way of replacing buried pipelines, pipe bursting was found in the 1970s in the uk. The method involves digging roughly 3-foot-by-3-foot entry and exit pits through the house and street, where service line meets the distribution line or water main. A cone-shaped drilling head using a slightly larger diameter compared to old pipe is inserted into an opening. The leading end of your bursting head is mounted on a pulling cable and also the back end is associated with HDPE pipe fittings. Because the bursting head is pulled through, it breaks existing pipe into pieces and simultaneously expands the diameter of your cavity for the new pipe.

The old pipe pieces just stay in the earth. Experienced crews can replace 3 or 4 service lines each day at 75 percent of the fee for cut-and-bury installation methods, Langston said.

“You take 25 % off of the price,” he added. “You don’t have to dig up people’s lawns or obtain people’s driveways. You spend less on being forced to replace those ideas and you’re not disturbing the city. In civil engineering, there’s a brand new aspect that’s rarely taken into account and that’s social interference. We always discuss cost but what isn’t measurable cost wise are definitely the calls and complaints to city offices about construction, noise, debris and dug-up yards. Several things are suddenly avoided using trenchless technologies.”

Livonia, Mich., used HDPE pipe from Charter Plastics Inc., the No. 77 ranked PPT extruder, to replace 27,000 feet of cracking, leaking iron pipes from April through October 2008. The Titusville, Pa.-based company has estimated sales of $35 million each year.

Livonia reportedly saved $200,000 on Charter’s pipe material alone in comparison to ductile iron and then used pipe bursting to setup it. Todd Zilinick, Livonia’s chief engineer, still tells his colleagues concerning the social and environmental features of PE pipe.

“One of your greatest benefits associated with high density polyethylene pipe is it’s simple to install, it’s less disruptive … and it also saves trees,” Zilincik said within a May 2016 testimonial for that Alliance for PE Pipe, that is located in Tulsa, Okla., and promotes the usage of HDPE pipe for municipal water systems within the U.S. and Canada as “the responsible infrastructure choice.”

HDPE pipe is joined by heat fusing above grade, which essentially generates a single pipeline without any leaks that could be miles long.

“It’s completely welded together,” Langston said. “It won’t leak, corrode or rust and it’s durable with a 100-year service life. It’s also completely inert. Nothing leaches from polyethylene pipe. In the event you have a look at each of the food packaging, be it milk, soda, water bottles or food, the fantastic majority of that is PE.”

Plastics Pipe Institute PE pipe has about 10 percent from the municipal water market, according to estimates.

PPI President Tony Radoszewski isn’t surprised cellular phone methods for HDPE pipe got a great deal of attention at the lunch-and-learn.

“There’s a great story for your plastic pipe – polyolefin type pipes like polyethylene – regarding trenchless installation,” he stated inside a telephone interview. “What it could do in terms of saving money is a big deal.”

As well as pipe bursting, smaller-diameter HDPE pipe can be used to replace existing pipes with a technique called slip lining.

“You don’t burst the existing pipe; you make use of it a host pipe,” Radoszewski said.

Then, there’s HDD for installing new lines of pipe. A drilling head is sent down an entry pit at an angle and leveled out for any distance. It will come support through an exit pit pulling new pipe behind it.

While telecom uses remain the one largest industry for HDD having a 24.1 percent market share, water uses are on the rise, increasing from 19.5 percent of HDD applications in 2015 into a projected 19.9 percent this season, according to the 18th annual Underground Construction HDD Survey released in June. Gas distribution is yet another strong HDD market with 18 percent share.

HDPE remains the No. 1 pipe materials used for HDD using a whopping 49.9 percent market share compared to 22.3 percent for PVC, 14.2 percent for steel pipe and 9.1 percent for ductile iron, the survey also says.

Flint is looking to replace approximately 5,000 LSLs and ten thousand galvanized steel lines, which corrode and then leave nooks where lead can settle, with copper. The current pipes were damaged when lead leached in the system once the way to obtain drinking water was switched from Lake Huron towards the caustic Flint River without the addition of any anti-corrosive agents.

Estimates to repair Flint’s water system using traditional copper pipe range from the city’s estimate of $55 million to $80 million and much more by others. Bids to change LSLs at 500 homes that are seen as the highest risk for lead exposure arrived “extremely high,” Mayor Karen Weaver said. The metropolis was expecting the fee to get about $4,000 per house. No bids were awarded for the reason that round and after follow-up meetings the area intends to go on with work at 250 houses by two contractors.

“I believe the bids arrived no less than fifty percent higher at $6,000 a home,” Langston said. “Copper may be the only material they’re allowing to spec now for service lines and ductile iron for distribution lines. Not simply is copper pipe for service lines 4 times the price of polyethylene pipe, however you have very extreme tips to get that copper pipe in the earth and that’s cut and bury, which entails digging up yards and streets.”

One or more Michigan lawmaker has publicly questioned why Flint doesn’t accept the “generous offer” from JM Eagle.

Nationwide, it would cost $1 trillion over the next twenty-five years to fix existing water to drink systems that happen to be reaching the ends of the useful lives as well as serve growing populations, according to the American Water Works Association.

The exact makeup in the buried water pipes isn’t known. Returning to the 1870s, the rollout of diverse pipe materials has evolved from cast iron, to cement-lined cast iron to asbestos cement then from the 1950s-60s ductile iron, PVC and PE.

Globally, the plastic pipe industry is forecast to boost in a compounded annual growth rate of 6.8 percent to 2020, according to a March 2016 market report by Lucintel, a consumer research firm based in Dallas.

The HDPE pipe market in Canada And America possessed a sales importance of about $5.54 billion in 2015 with JM Eagle holding about 18.48 percent of sales, based on Acute Market Reports. As well as drinking water, HDPE pipes carry wastewater, slurries, chemicals, hazardous waste and compressed gases.

Other PE pipe potable players include Performance Pipe of Plano, Texas; Dura-Line Corp. of Knoxville, Tenn.; and Pipeline Plastics LLC of Westlake, Texas. The companies rank seventh, eighth and 43rd, respectively, in Plastics News’ latest ranking.

While PE will be the No. 1 pipe materials in water systems in Europe, it is actually still making inroads in america. Langston estimates that PE pipe has 10 percent of dexqpkyy02 municipal marketplace for both water and sewer applications. PVC has many of the plastic pipe market share.

“We’re 10 % nationwide but when you go to states like California we’re 50 % because HDPE pipe is definitely the only material which is earthquake and ground-movement resistant,” Langston said. “A study by Cornell University performed on 16-inch pipe showed you could have 4 feet of lateral shift along with the pipelines won’t yield. It stays intact.”

Freeze-thaw cycles in northern states like Michigan and drought conditions in Texas also cause the ground to maneuver, making PE pipe an excellent choice, Langston said.

“It doesn’t matter where you live in the nation, you’re likely to have ground movement,” he added. “When you appear at pipe failures, the primary reason for this is bell-and-spigot separation. The pipe pulls apart. But for those who have a fused, welded system, such as polyethylene, the pipe just moves together with the ground. There are no problems.”

Florida is yet another big marketplace for PEX-AL-PEX pipe as a substitute material for corroded metal pipes, Langston said.

Elsewhere, material acceptance can appear similar to a slog. You will find mayors, council members, administrators, engineering firms and public works employees that need to purchase in to the change to PE.

“We are constantly going all over the country discussing PE pipe,” Langston said. “The interest is exceedingly amazing however the change process is slow.”
