In the early 1930’s, Harry R. Crane founded Flexible Sewer Rod Equipment Company which manufactured plumbing specialties. Among their product lines were 5/16 x 36” sectional steel rods that could be outfitted with various attachments for cleaning mainline sewers. This innovation is said to have brought sewer workers out of the manhole into a safer environment above ground. From there, the first rod power drive was developed and patented. The product line has expanded to include bucketing machines, high power rodding machines and high power flushing machines.

The company is known today as Sreco Flexible Inc., an industry innovator which has continuously served the marketplace for over 75 years. During their long history, they have consistently created, developed and expanded the product line to address the needs of sewer cleaning and video pipe inspection workers in both domestic and international markets.

Shamrock is proud to announce SRECO Flexible Inc., as a sister company. We appreciate their strength and durability in the marketplace and together our companies will strive to maintain the confidence and trust of our customers.

Innovative, Tested Design
By listening to customers and monitoring the industry, SPT engineers anticipate needs and design new products. Every prototype is tested. Shamrock Pipe Tools uses a diesel powered test unit with a high capacity pump to take every new nozzle prototype beyond its working range to see what it will do. Manufacturing does not begin until the nozzle design has been proven at its rated level. Even poorly designed or manufactured nozzles can perform at their rated level once, but a tested new design performs at its rated level from the first to the last use.

Appropriate Raw Materials
Only the most appropriate metal is used in every product. The most appropriate material is not necessarily the least expensive. Shamrock Pipe Tools uses only tool quality metals such as knife-grade stainless steel and the hardest aluminum in its nozzles in order to guarantee designed performance and wear. For example, SPT tested various wear resistant materials for its jet inserts before finding the right product. SPT discovered that a carbide insert, properly manufactured, outlasts an insert made of any other material. Inserts examined after 10 years of service were found usable.

Precise Manufacturing Processes
Precise, computerized machining practices eliminate imperfections in each nozzle that can disrupt flow or degrade performance. After machining, Shamrock Pipe Tools heat treats many of the nozzle styles to guarantee tight, efficient streams of water that transfer all of the nozzle’s horsepower to the sides of a pipe where they are needed.
