Working closely with its customers in the field, BASF supplies high-quality polyurethane pipeline support to operations around the world. BASF pipeline foam is field-applied and formulated for safe application
BASF formulates polyurethane for the following applications
Water barriers or breakers support a pipeline by restricting the movement of water or aggregate on a sloped surface. Unlike sand bags, polyurethane breakers can be sprayed vertically without the need to pyramid and are built without the aid of a form. Polyurethane breakers are also labor-efficient. A two-person crew can install a breaker in an average of three minutes each, allowing the crew to keep up with the pipeline spread. Polyurethane breakers can also be applied in adverse weather and on extreme terrain, remaining in place even if soil erodes beneath them.
Polyurethane ditch pillows protect and support pipeline from the surrounding surfaces. The advantages of polyurethanes versus traditional sandbags in this application are many: pillows are lightweight and easy to install and can be sprayed in place on site. A mobile pillow facility also means that cured product does not need to be transported long distances, saving time, costs and labor. It is also safer, as crew members can spray the product from outside of the ditch. BASF Polyurethane pillows can also be applied under adverse weather conditions and over a wide variety of terrain and are both corrosion-resistant and do not cathodically shield.
BASF supports its performance in this category with an extensive track record:
Polyurethane foam offers a faster and less labor-intensive alternative in rock shielding than traditional methods, such as rockguard or sand. Typically applied two inches thick, a crew of two can apply over five kilometers of two-inch pipe per day, although speed of application will be affected with an increase in pipe diameter.
Innovative and high-performance, polyurethane joints are applied via an injection mold process. In this process, a mold is fitted over the weld gap on the pipe and the foam is injected, expanding on all sides to completely fill the void. The expanded foam bonds to the existing foam around the pipe on both sides of the weld, creating a completely sealed weld joint.
