Buttweld Fittings manufacturing process includes a series of steps like Annealing, Straightening, Pickling & Passivation and Polishing. These fittings are produced using latest technology, ensuring excellent strength and long service life. The process needs a lesser amount of heat treatments to ensure better physical properties.

The series of steps involved in the manufacturing Process of Buttweld Fittings are given in a detailed view below:

Annealing :
Annealing is also known as heat treatment, which plays an active role in the production. In this step, the tubes are carried out in fully automated and conveyor to heat them at certain temperature. Once the tubes get heated, they immediately quench in water.

Straightening :
The tubes are straightened with the help of straightening machine to provide a high degree of straightness in this step.

Pickling :
The process of Pickling refers to the removal of high temperature scale and adjacent low chromium layer of metal from the surface of stainless steel.

Passivation :
Passivation is the process of treating the surface of stainless steels in order to eliminate the contaminants from the metal. The process also helps in promoting the formation of a continuous passive film on a freshly created surface.

Polishing :
The final step, is named as Polishing that reflects the wonderful quality, high aesthetic & hygienic value and high durability of buttweld fittings. Polishing is a essential step to gain excellent features for meeting the varied demands of clients.

(Duplex stainless steel plate USE : Duplex stainless steel plate is often used for storage tanks. High corrosion and erosion resistance is a must for storage tanks, whether the designer wants to prevent leakage during desalinization, avoid contamination in pharmaceutical or food processing, or store chips as well as black and white liquor for the pulp and paper industry.)
