DN125 5'' Double Wall Concrete Delivery Pipes For Putzmeister / Schwing Pump Car

• The hardness of the inner pipe up to HRC65 With double structure,it makes more wear proof.
  The tensile strength of the outer layer over 600Mpa, it makes more safety and reliable.
  Inner pipe of flange in two side adopts high-chromium alloy which improves local abrasion-resistance.
  The special parts extend flange,it makes the lifetime being more than 30%.

Advantages:

1. Twin wall elbow ’s service life and working pressure are better than the casting. Besides, The Twin wall elbow’s structure ensures high abrasion resistance and toughness.

2. Chromium alloy iron casting enables the liner highly wear proof and reduce pressure

3. Seamless welding enables the the outer layer hard to explode

4. Light weight improves vehicle efficiency, highly reduces labor and cost and the time for replacement
