Vertical Drycast Concrete
Key Facts:

  • V.D.C. is the most advanced process in the world today;
    resulting in:
  • Highest quality design
  • Best performance
  • Modern production process creates the densest
    V.D.C. on the market
  • Greater overall durability
  • Greater collar durability
  • Less damage from site handling
  • Reliable quality and advanced technology
INNOVATION & STRENGTH

Austin Pipe Concepts manufactures Reinforced Concrete Pipes by the V.D.C. method.

Reinforced Concrete Pipe is recognised by Engineers, Contractors and Specifiers throughout the modern world as the most durable, versatile and economical of all pipe products.

Our pipe making technology produces high strength densely compacted concrete by way of the vertical drycast process.

This high density pipe is less susceptible to damage during shipping, installation and in service use.

Innovative Technology for Optimal performance
In the Concrete Pipe Industry

QUALITY

The Variant machine combines the outstanding compacting qualities of Schlosser Pfeiffer’s proprietary vibration technology with a wide range of sizes.

Machine construction follows stringent quality guidelines ensuring all equipment used in the manufacture of V.D.C. is of the highest consistent quality.

Quality Control FLEXIBILITY

The Variant Pipe making machine offers the ultimate in dry cast flexibility. Each machine is individually adjusted for every application and combines user friendliness with reliability and easy maintenance. This operational flexibility allows for versatile production.

DEVELOPMENT DESIGN AND ENGINEERING

MANUFACTURE The Variant machine has been developed and designed using state of the art technology and equipment. The materials and components used in the manufacture of the machine are selected to meet the strictest quality requirements. This results in low manufacturing tolerances and a correspondingly high standard of V.D.C. pip

 

Variant Machine

Schlosser Pfeiffer Machinery
Schlosser Pfeiffer are regarded internationally as world leaders in the manufacture of vertical dry cast concrete pipe.

V.D.C. pipe is made using inner and outer mould formers placed in a vertical aspect. The pipes are cast below floor level, which reduces noise levels, ensures staff are not working at height and also keeps factory and crane heights to a minimum.

The concrete is filled evenly into the mould by way of a rotating feeder belt. Once the dry concrete mix is placed into the assembled mould sections the inner is vibrated to ensure even and dense compaction of the concrete is achieved.
Schlosser Pfeiffer have developed the technology for placement and vibration of the concrete such that uniform compaction, consistent wall thickness, perfect cover to reinforcement, smooth inside and outside surfaces and tight dimensional accuracy are features of the pipes produced using this methodology. The spigot end of the pipes is formed by way of a profile ring.

Once the process is complete the formed pipe and the outer mould are then stripped from the inner former and placed in storage. The outer former is then removed, leaving the finished product to cure. This process reduces the amount of handling and ensures minimum potential damage to the pipe.

FEATURES

 

  • P.V.C. and P.E. liners able to be integrated into the manufacturing process.
  • Cast-in lifting anchors
  • Proven performance and strength, consistency of product
  • Jacking and thrusting pipes in arange of diameters
  • Pipe available for stormwater, sewer, watermain, pump chambers.

ADVANTAGES
  • True 100 year defined life
  • Consistent product wall thickness
  • Even distribution of aggregates throughout the pipe cross section
  • Even tolerance due to vibration process
  • Perfect cover to reinforcement with dimensional accuracy
  • The process requires a thicker pipe wall than the existing produced product; this has a number of advantages and benefits to the specifer, asset owner and contractor
    • Thicker wall giving greater cover to reinforcing
    • Thicker collars and spigots being less susceptible to damage
    • As the pipe is heavier lifting pins will be incorporated down to 450mm diameter

 

BENEFITS
  • Lower production costs, offering a more robust product and less energy required to manufacture.
  • Faster delivery of product due to efficient manufacturing process.
  • Lower labour costs, offering more efficient costings to product.
  • Production method uses a dry concrete mix and is proven to be a very safe and environmentally friendly process; there is no slurry produced
