Krah machine is a machine for producing carat pipes, that is, high-density polyethylene (HDPE) wound structural wall pipes in a hot state. The wall pipe of the Krah machine is made of high-density polyethylene resin as the main raw material. The Krah machine adopts a hot-winding poplar-type process. The Krah machine uses a polypropylene (PP) single-wall corrugated pipe as a support structure and has a high resistance to external pressure. The carat tube products of the Krah machine can be divided into four series: PR, OP, SQ, and VW.

Introduction of Krah machine

Krah machine's carat pipe products can be divided into four series: PR, OP, SQ, and VW. Among them: Krah machine's PR and OP-mainly used as buried drainage pipes, and Krah machine's SQ-mainly used to make containers or manholes. Krah machine's VW- is mainly used for tees, elbows, and second-processed pipe fittings. The most widely used Krah machine product is the PR series. The inner surface of the Krah machine is smooth, and the exterior is a special-shaped reinforced structure. The standard length is 6 meters, the inner diameter of the Krah machine pipe ranges from DN300-DN4000, and the product indicators all meet the requirements of GB/T 19472. 2-2017 B-type structural wall pipe standards and EN-13476 European standards.

 

Performance characteristics of Krah machine's HDPE winding structure wall pipe

1. Krah machine hot winding forming high quality of weld seam. The flat strip and U-shaped strip in the molten state are extruded from the Krah machine extruder die, and the Krah machine is evenly wound on the heated Krah machine according to the predetermined position. On the roller mold, the quality of the welded joints of the Krah machine structural wall pipe is guaranteed. Especially in the structural design of the Krah machine, the welding seam of the flat strip is covered by the polyethylene-coated support tube, which improves the overall resistance to external pressure of the product.

2. Excellent installation performance of the Krah machine The pipe connection of the Krah machine adopts the electric fuse connection technology with the same material embedded in the socket, and the Krah machine connection quality is high. It can be 100% leak-free, ensuring the same life as the Krah machine pipeline system and the safety of operation. At the same time, because the Krah machine product is lighter than other pipes under the same application conditions, it is easy to transport, convenient, and quick to construct, and can reduce the construction cost. In the scope of application, the Krah machine does not require a concrete cushion and concrete pipe foundation trenches. Direct pipe laying, basically the Krah machine can excavate, pipe down, and backfill while simplifying the construction procedure and shortening the construction period. During project acceptance, the Krah machine adopts closed air inspection instead of closed water test, which not only speeds up the acceptance but also saves the complicated work and a lot of test costs in the closed water test of the Krah machine.
