The boiler body seen above has a diameter of 1000 mm. The thickness of the material is 8 mm and body length is 2000 mm.
There are some points in cylinder bending. The most important one is that if the join remains flat then the boiler diameter can not meet the requirement. To have a regular join requires utmost attention and experience.
One of the most important things in pipe welding is the welding bend. The welding is strongly durable where the welding bend is properly performed. These pipes can be lathed as requested or can be directly used in high pressure environment where the pressure is within the limits according to the specifications.
The material type to be used for high temperature environment like as heat treatment is AISI 310. The operating temperature of this material is above 1000°C.
In these types of drums, there is more gain in strength where there is less joints. Therefore conical parts are manufactured from 2 identical pieces and has just 2 welding joints.
The drum body is also manufactured from 2 identical parts which are assembled by welding. The seals are located on the edges purposely as the corner turns are more durable when compared to surface plate. When assembling the conical parts to the drum body, the seals on the conical parts are located asymmetrically with the seals on the body. The reason for this is also to increase the strength.
Original AISI 310 welding wires are used in all welding processes.
And now the “heat treatment drum”, which will be exported, is encased and ready for delivery…
These perforated pipes are used in textile industry as a component of cone dyeing machines. They are manufactured from AISI 316 stainless steel.
Yarn is winded around these pipes and placed in a boiler like equipment. And here the dyeing process begins and varicoloured yarns are made.
This bell-mouth equipment has been manufactured as a demand of our customer who is producing milk separators. The material is AISI 304.
When manufacturing this type of equipment, which to be used in food sector, it is very important to have a very smooth welding process. Both inner and outer surfaces need to be cleaned.
The production has been finalized by a rough grade at our site and delivered to our customer. On customer site, the equipment is going to be sandblasted and be ready for the final use.
