Smooth and innergrooved tubes

K65 - Sustainable and efficient

Sustainable and efficient – two keywords that have had a decisive impact on our time and have gained in relevance in recent years, especially in refrigeration. Increased environmental awareness in society and industry has therefore led to a kind of renaissance of natural refrigerants, especially CO₂. Wieland supports this turnaround with a tube system that meets the high requirements of CO₂ as a refrigerant.

Wieland K65 tubes have been designed for CO₂ applications in the commercial field, especially that of supermarket refrigeration systems. Wieland K65 alloy provides the mechanical strength high enough to withstand the high operating pressures of CO₂. At the same time, K65 tubes have outstanding processing properties, similar to those of standard copper (Cu-DHP/C12200). 

All Wieland K65 tubes are available in the soft condition (R300/O61) to ensure excellent bending / flaring and collaring properties.

Wieland K65 tubes are offered from stock in two pressure ranges, 80 bar and 120 bar, and in dimensions ranging from 3/8” up to 2-1/8”.

Moreover, K65 tubes are also available in individual dimensions and different delivery forms.
For industrial processing, in particular CO₂ heat exchanger (evaporator / gas cooler) manufacturing, level wound coils (LWC) are offered.

What is a profile tube?
Profile tubes are manufactured from round pressed or also drawn tubes. Depending on the requirements, the final shape is produced by cold forming in various processing steps.
produced. This makes sectional tubes a sensible, cost-effective addition to conventional
extruded profiles. 
Complex geometries, thin walls, high precision. 

Areas of application
Wieland sectional tubes made of copper materials are mainly used in industries that place special demands on the material and have to ensure high reliability of the end product
reliability of the end product: These include electronics and electrical engineering, the sanitary industry or architecture.
Other possible applications for our profile tubes are in model making, medical technology, automotive engineering and the manufacture of writing instruments or musical instruments. In particular
For foundry applications, Wieland also manufactures large, square or round profile tubes for ingot molds.

Dimensions
Production is carried out according to your drawing. 
Profile tubes can be manufactured from round tubes with a diameter of 5 mm up to a diameter of 230 mm. Depending on the alloy or diameter, the wall thickness may be
can be selected between 0.1 mm and 15 mm. The inner cross-section must be at least 5 mm2 and the smallest diameter of the circumscribed circle at least
5 mm. The ratio of the largest circumscribing circle to the smallest wall thickness must not exceed 125:1. We supply profiled tubes up to 10 m long, in exceptional cases up to
in exceptional cases up to 18 m.

Materials
Starting materials for sectional tubes are primarily copper materials or lead-free brasses. Depending on the application, other material groups may also be used:

• leaded machining brasses
• special alloys 
• tin bronzes 
• New silver

The good cold formability of the material extends the design possibilities for the
in the design of the sectional tubes.
Depending on the application and the resulting requirements on the material
on the material, the profiles can be designed in different strength states
from soft to hard;

We will be pleased to advise you on our alloys and dimensions 
 

We manufacture seamless tubes with outer diameters up to 320 mm. They are suitable for electrical engineering and telecommunications, heat transfer and apparatus engineering.
Low-alloy copper materials with higher strength serve as brake line tubes in motor vehicles.

We have specialties such as dezincification-resistant materials in our range, and alloys with high wear resistance, as used in crude oil production.

Handrails, shower bars, towel rails, handgrip elements, water inlets and outlets, drains, decorative claddings: For these and many other products, the metal
The metal goods industry uses tubes made of copper alloys for these and many other products.

The packaging 

By choosing the right packaging, your individual needs for transport, storage and processing can be taken into account. 
Thus, the excellent product quality is preserved and a comfortable processing is made possible. 
Based on our experience, we offer you proven packaging materials - we are also happy to find an individual solution. 

Each package is labeled on the front side to ensure clear identification and traceability. 

Sustainable by conviction: 
Wieland uses reusable packaging for the most part to protect the environment.  
This also benefits you - you save disposal costs.
