Get Acrobat Reader MULTI-AXIS® Plastic Lined Pipe

  • Eliminates flange connections at elbows.
  • Sections are bent at any angle up to 90° with a tolerance of ±1°.
  • Reduces pressure drop across the bend and reduces energy costs.
  • Longer bend radius (3 diameters vs. 1.5 diameters).
The Bending Process

Although the concept behind MULTI-AXIS® pipe is simple, successfully bending swaged plastic-lined pipe is not. It is considerably more difficult than bending unlined pipe. As for loose-lined pipe, it is virtually impossible to bend without distorting the liner. The liner in Resistoflex Plastic-Lined Pipe is locked into position and resists distortion.

Resistoflex uses special bending equipment and proprietary manufacturing techniques to provide bends in any angle up to 90° and compound bends on a single section of pipe. MULTI-AXIS® pipe is a high-quality product with dimensional tolerances of ± 0.125" (3.2mm), even on pieces with multiple bends. Due to the complexity of the bending operation, field bending of MULTI-AXIS® pipe is not available. MULTI-AXIS® pipe can be supplied with Class 150 steel rotatable flanges or with plain ends that can be joined in the field with other plastic-lined pipe sections using CONQUEST® flangeless connections.

When considering MULTI-AXIS® pipe, it's important to carefully examine directional changes in a system to determine whether the centerline-to-face or centerline-to-centerline dimensional requirements of bent pipe can be met within the parameters of the initial design. If not, design adjustments may be required.

Center-center and center-face dimensions = +/- 1/8"
Bend angle = +/- 1°

Note: Angle can be within 1 degree of specified angle. If there is a long run of straight pipe after the bend, this can result in the center of the next bend or the face of the flare being offset an inch or more from what was intended. In most cases, this can be compensated for in the field installation. In the case of bolting MULTI-AXIS to flanged equipment that is in a permanent fixed location, the offset may present an installation problem.

Applicable Codes and Standards

MULTI-AXIS® pipe meets the ASTM F1545 standard specification for Plastic-Lined Ferrous Metal Pipe, Fittings and Flanges. MULTI-AXIS® pipe also meets certain ASME B31.3 requirements.
