6-Layer Automotive Fuel Delivery Tubing Systems – Just One Of Our Leading Edge Technologies

Davis-Standard’s pipe, profile, and tubing systems have been a global leader in multi-layer tubing, medical tubing, agriculture pipe, telecommunications pipe, and building profiles for over 50 years. Continuous improvement in extruder, controls, feedscrew technology and process support has allowed Davis-Standard to become the global choice for processors of high tolerance tubing, high output gas and water pipe lines, and custom profile systems. From single extruders to complete systems, look to Davis-Standard for your global pipe, profile and tubing needs.



Davis-Standard’s pipe, profile and tubing extruder range is as broad as the application areas we support. Every extruder is available with a range of control systems and feedscrews to achieve results-driven performance.

  • Super Blue® and Euro Blue® extruders are built with the same high quality components as our engineered machines. Extruder stock orders are built for quick delivery with two to four week shipments common for 3 1/2-inch, 2 1/2-inch, and 2-inch machines.
  • HPE single screw co-extruders, (3/4 to 1 3/4 inches) incorporate a direct motor drive system eliminating the need for drive belts.
  • The MEDD line of medical extruders is designed with water-cooled permanent magnet synchronous motors, eliminating the need for oils and grease inside a clean room. The extruder base is also the control panel providing space-saving layouts for clean room applications.
  • The high output, low melt temperature Thermatic® groove feed single screw extruder is engineered for the demanding water and gas pipe industry. A 3 1/2-inch 38:1 groove feed extruder in our Connecticut lab is available for output and mixing testing on your materials.

Davis-Standard is a global leader in the design and manufacture of HDPE pipe and tubing systems. Our technology covers all the major markets and includes advanced control system technology. Examples of major markets we support worldwide include telecommunications, construction and agriculture.

  • Telecommunication HDPE duct for fiber optics including multilayer HDPE and silicone microducts, and packaging of several microducts into a common HDPE cover
  • PEX tubing for home heating and cooling including single layer PEX and PEX with an EVOH outer layer
  • Agriculture corrugated drainage pipe co-designed with major corrugator suppliers, including high-pressure melt pumps, continuous screen changers, and gravimetric feeding systems

Davis-Standard understands the needs of the global medical tubing market  – tight tolerances, high speeds, clean room specific designed equipment, and process support. We work with your engineering team to design the right system for your tubing needs, including extruders, controls, tooling and screw designs. Our lab lines in Pawcatuck, Connecticut and Suzhou, China support new application development such as microbore catheter tubing, multilumen tubing and bump tubing. We recently expanded upon our melt pump product line to offer customers a complete extruder and melt pump package for new lines. The pumps may also be added to existing systems for better process control.
