Piyush steel is famous exporter, manufacturer as well as a supplier of the alloy 20 flanges across India. The product which we manufacture gives exceptional performance. We stabilize the alloy 20 flanges with columbium and minimize carbide precipitation while welding. Alloy 20 flanges excel especially in resisting corrosion and hot sulfuric acid as compared to other grades.
Some of the greatest features offered by the alloy 20 flanges are resistance to pitting as well as crevice corrosion in sulfuric and the chloride-containing the environment. The copper content of the alloy 20 protects it from sulfuric acid attack. Alloy 20 flanges made by us in different sizes as well as shapes as needed by the customers. Welding of the alloy 20 flanges can be done via MIG, TIG and SAW by using the matching filler.
All the national and international norms are followed by us while making these flanges. Standards in which you will find these flanges are BS flange, ANSI flange, EN flange, ASME flange. Some of the types of flanges which we make are alloy 20 slip-on flange, weld neck flange, orifice flange, blind flange, threaded flange, socket weld flange, etc.
Table Of Content
These flanges which we make can be used in various industrial applications. Some of the industries which make use of these flanges are pharmaceuticals, power generations, gas processing, condensers, heat exchangers, chemical equipment, specialty chemicals, pharmaceutical equipment.
When we manufacture these alloy 20 flanges we follow a sequential process which includes testing, inspection, packaging, etc. We make sure that we use the high-quality raw material which is from the reputed vendors. We make sure that raw material is of optimal quality and as per the national and international standard. Our expert team is responsible for carrying out the manufacturing process. They make use of advanced tools and techniques in order to produce these flanges. They make the flanges which have accurate dimensions and finishing.
This is the process which is followed by the manufacturing of the product. In this process, each product is tested individually so as to find errors and damages in the product. Also, tests are conducted to check the quality and durability of the product hence, both destructive and non-destructive test plays an important role in the production process.
Some of the test we conduct are hardness test, flattening test, mechanical test, PMI test, micro and macro test, IGC test. All these tests when passed by our product then it a report of testing is made and further, it is put forward for inspection.
In this process, the product we manufactured is visually and by hand-inspected by the third party. They determine the product quality and make a report. This report is proof that our product is safe, there is no impurity in our product and that it fits the industrial standard.
We also prepare documents related to alloy 20 flanges such as fumigation certificates, commercial invoice, raw material test report, guarantee letter, heat treatment charts, etc.
Some of the test certificates are offered to clients in addition to the product so as to ensure that the product they are receiving is of high quality.
Packing material we make use of are also of good quality. The packing materials which we commonly use is the environment-friendly poly bags or wooden pallets, boxes, etc. The package ensures that the product remains safe from dust, dirt, and damages from the external environment. Thus, the product is maintained in good condition and delivered on time by us.
We ensure that as soon as you place an order we start manufacturing the alloy 20 flanges and deliver it within short period.
