From risky beginnings to industry leadership: how ISCO’s commitment to innovation shaped golf course irrigation. <\/strong><\/p>\n\n

Tried<\/h2>\n\n

From its roots in pioneering HDPE irrigation on golf courses – to maintaining a place as the industry leader, and now ISCO CEO Jimmy Kirchdorfer’s role as lead owner of Valhalla Golf Course in Louisville, Kentucky, ISCO’s name is synonymous with golf. <\/p>\n\n

One doesn’t ascend to these heights by chance or luck. <\/p>\n\n

When Jim Kirchdorfer Sr. installed an HDPE irrigation system at Quail Chase golf course in Louisville in 1987 there was risk involved. It was a new material. There was skepticism from the outside. Internal knowledge of the qualities that HDPE possessed knew it was a minimal risk. <\/p>\n\n

With that approach, ISCO has been able to sit in the clubhouse with the low score on the card while other suppliers hack away on the metaphorical course. <\/p>\n\n

You can pass along your mistakes to your clients through trial and error as you grow, but that isn’t how ISCO operates. <\/p>\n\n

Tested<\/h2>\n\n

With multiple testing labs in the 39 North American locations, any errors that come as a result of a trial happen in-house, as opposed to the job site. <\/p>\n\n

With that experimentation, the best possible practices are implemented in the countless golf courses where ISCO has installed HDPE irrigation systems. <\/p>\n\n

One of the more debated practices is the joining of pipe and fittings with dissimilar DRs. <\/p>\n\n

There are clear American Society for Testing and Materials (ASTM) standards that address this process, and ISCO has utilized this process at virtually every golf course installation. <\/p>\n\n

The use of pipe and fittings with dissimilar DRs is not limited to irrigation but is also prevalent with other applications including the most volatile: natural gas. <\/p>\n\n

But there is somehow still reluctance among some installers. <\/p>\n\n

Much like those who hesitated at the HDPE installation Quail Chase in the 80s. <\/p>\n\n

The mindset marked by hesitancy toward innovation has led to extra time and cost with more expensive fittings and labor devoted to beveling the ends of the pipe. <\/p>\n\n

In a transparent effort to erase any doubt – ISCO returned to the lab and fused a single piece of six-inch DR 11 HDPE to a pair of 13.5 fittings: an end cap on one end and a flange on the other. The same was done with DR 11 pipe and fittings. <\/p>\n\n

The heat soak and pressures when fusing unlike DRs are outlined in ISCO’s fusion manual, which accompanies all ISCO fusion equipment and is available online. <\/p>\n\n

In the hydrostatic testing lab, engineers attached a blind flange plate to the flange end of the spool piece, filled the pipe with water, and attached it to the air hose. <\/p>\n\n

In the testing tank pressurized air was forced into the spool piece until it failed. <\/p>\n\n

The process gives answers about the durability and integrity of the pipe and welds but also confirms the leak-free quality of fused HDPE pipe and fittings, otherwise, the test could not be performed. <\/p>\n\n

Per ASTM standards the spool piece should reach a failure point at 3.2 times its working pressure to be within specifications. <\/p>\n\n

The spool piece with DR 13.5 pipe and DR 11 fittings has a pressure rating of 160 PSI and did not fail until 760 PSI – 4.75 times the pressure rating. <\/p>\n\n

True <\/h2>\n\n

Despite the differing DRs, the fusion points and fittings were not compromised. <\/p>\n\n

The thicker-walled DR 11 pipe and fittings, which have a pressure rating of 200 PSI, sustained pressure up to 900 PSI before failure – 4.5 times the pressure rating. <\/p>\n\n

Once again it was the pipe that eventually failed, not the fusion joints and fittings. <\/p>\n\n

With experimentation, the best possible practices are once again implemented in the field. <\/p>\n\n

ISCO has tried it. <\/p>\n\n

ISCO has tested it. <\/p>\n\n

And it remains true. <\/p>\n\n
