Variety of Flanges offered by Piyush Steel-
We serve variety of flanges that are common in the market to our global as well as domestic customers. The stainless steel orifice flanges are used by the water, breweries and sugar industry. Thus, they have high pitting resistance which makes them work as a leak-proof seals. Our stainless steel slip-on flanges have combination of chromium-nickel-molybdenum. This combination gives them reliable sturdiness, formability and fabricability of unmatched degree. The flanges work properly even at high temperatures. The weld neck Stainless Steel 317L Flanges are suitable to work against intergranular corrosion. Thus perfect for working in pipelines that transport solids and liquids in industry such as textile and food processing. This better performance is due to hot as well as cold worked treatment. Our socket weld flanges offer excellent corrosion resistance, non-magnetic properties due to chromium and nickel content in low composition. The ring joint flanges have high strength that comes from light cold working on it. The blind flanges manufactured at Piyush steel have excellent properties like formability, and excellent weldability along with notable cryogenic properties. They are also known for good hygiene factor. Also, we offer Stainless Steel 317L Flanges of threaded, reducing, spectacle blind types.
Manufacturing process at Piyush Steel-
We realize the importance of good products at different industries thus we understand the customer’s requirement better. We ensure that we supply what our customers have asked for and we ensure this with our quality assurance plan. The most important step to complete the requirements of our customers begins with the right manufacturing process. We follow given below process for manufacturing Stainless Steel 317L Flanges.
• We Begin with certified Raw materials
• Variety of cutting methods used to get pre-defined sizes and shapes
• Setting and welding process including pressing, heating, forging and forming
• Products are machined with first class quality machines at machine shop
• Grinding process done with great efficiency
Inspection process is a vital step at Piyush Steel. The inspection is done by the third party agencies that are ISO 1720 certified. We don’t participate during inspection process by them thus giving them independent and impartial conditions to carry out the inspection. The inspection process usually involves the following activities:
• Sand blasting
• Heat treatment
• Radiography test
• Ultrasonic test
• Determination of physical as well as chemical composition in raw materials Along with these, the third party inspects quality, quantity, marking and loading, as well as packing of flanges. After getting a check from them, an inspection certificate is issued which we deliver to the buyer along with the other related documents.
The final process at Piyush Steel is dispatching. This is tedious of all tasks and thus carried out by the use of heavy duty cranes. We serve the products to our esteemed clients through our extensive delivery chain where our international clients receive the timely shipment of Stainless Steel 317L Flanges. We are dedicated to live upon the expectations and requirements of our clients related to any products.
The hardness of 317L stainless steel flange is typically between 25 and 40 HRB (Rockwell Hardness B scale). Due to its low carbon content, this property makes it one of the harder grades of stainless steel but still relatively easy to work with. This also makes it an ideal choice for applications requiring a durable, corrosion-resistant material that can withstand high temperatures.
The difference between 317 and 317L stainless steel flange is chemical composition. 317 stainless steel contains higher levels of chromium, molybdenum, and nitrogen, while 317L has a slightly lower chromium content and no added molybdenum or nitrogen. The result is that 317L has improved weldability and better corrosion resistance compared to 317 stainless steel.
