Since 1981, Cyntech Group has built a solid reputation as an industry leader in the design and manufacturing of pipeline anchor systems and accessories. With over 110,000 anchor sets installed worldwide, our anchor systems have been proven to hold up under field conditions in numerous installations by leading corporations in the pipeline industry and can be custom designed for your specific application. Our range of anchors, combined with our exclusive polyester pipeline saddle, provide unparalleled pipeline buoyancy control and cost savings.
Cost savings up to 80% can be achieved over traditional pipeline buoyancy control methods. Our anchor systems eliminate the need for concrete weights, concrete coated pipe, and geotextile bag weights to control buoyancy. Personnel and transportation costs, and GHG emissions are all reduced significantly with our exclusive anchor system.
Cyntech will provide complete turnkey design and installation services, or our professional engineers and technicians will work with you to specify the optimum anchor system for your project. Our advanced anchor designs, combined with our exclusive, non-corroding, low-stress polyester pipe saddles, provide unparalleled performance and longevity, regardless of the installation environment.
We offer a range of anchors for pipe sizes from 10 to 48 inches. Our exclusive polyester pipeline saddle provides universal contact with the pipeline while the elasticity of the polyester belt ensures that the load is shared equally between anchor points. There is also no metal-on-metal contact with pipe.
Our anchor system is designed to provide a hold-down capacity of 2.5 times the buoyant force of the empty pipeline, with typical spacing for an NPS-24 pipeline of 33 meters. Compared to concrete weights, our anchors require less transport and storage space – materials for 10 kilometers of NPS-24 pipeline comprise three truckloads and require just 30 square meters of storage space. Personnel and equipment requirements during installation are reduced – A typical anchor installation crew consist of a five-ton picker truck with a hydraulic drive unit, an operator and two laborers.
The advancement of sophisticated pipeline stress analysis methods has resulted in greater understanding of why pipelines fail and what can be done to prevent it. Collaborating with the world's premier pipeline engineering firms, Cyntech designers developed a simple-but-effective method of reducing thermal expansion-induced overbend stresses.
In addition to our standard buoyancy control anchor systems, it is now the standard practice of some of the most well-known players in the pipeline industry to utilize our stress mitigation anchor systems, providing permanent protection against excessive stress, upheaval, and buckling.
Our stress mitigation anchor systems are implemented in much the same way as our standard anchor systems. They are designed to resist greater uplift forces and use specialized saddles to distribute those loads over a greater contact area of pipeline.
Additionally, multiple anchor options are available which allow for anchorage in all types of geotechnical conditions, from extremely weak clays to solid rock.
Our anchor systems can result in cost savings of up to 80 percent compared with traditional pipeline buoyancy control methods.
As our anchors are lightweight and compact, materials, storage, transportation costs, and the need for personnel and equipment hours are all reduced significantly. Our exclusive systems also eliminate the need for concrete weights or concrete coated pipe to control pipeline buoyancy.
When comparing the cost of Cyntech Group pipeline anchors versus concrete weight or bag weights, it is important to be accurate.
For example, concrete weights may cost around $550 per weight while an anchor set may cost around $1900 per set. Because of the greater capacity and spacing of the anchor set, it is important to calculate the cost of pipeline per meter in addition to the complete supply and install for each method of buoyancy control (including shipping, storage clean-up etc.). This will help determine an accurate number.
Typical concrete weight spacing is five metres while our anchors are spaced at 33 meters. As the chart below shows, there are cost savings to be made. 100 kms of 30-inch pipeline would require 20,000 weight (approx. $11,000,000) versus 1900 anchor sets at a cost of $4,180,000, providing savings of 62 per cent. In this case, weights cost $110 per metre, and our anchors cost as little as $41.80 per metre. The same cost analysis method should be used for bag weights and other weight-type buoyancy systems to compare the true cost of the different buoyancy control methods.
In other words, the greater the pipe diameter, the greater the possibility of increased savings.
