Alloy 20 Buttweld Fittings Manufacturer & Supplier in India
Alloy 20 buttweld pipe fittings are commonly utilized in the industries having corrosive and high pressure environments such as chemical processing, pharmaceuticals, petrochemicals and food processing. The aim of these fittings is to produce robust welded joints with flow characteristics that are smooth and reliable over time in piping systems that are critical. Alloy 20 buttweld fittings are made in accordance with ASTM B366 and UNS N08020 standards, and are best used in a system where resistance to aggressive chemicals and consistent performance are required. ASTM B366 UNS N08020 Buttweld Fitting are made with high durability that make them applicable in the harsh service conditions when the traditional materials might not provide adequate performance.
The excellent corrosion resistance and mechanical strength are known to be found in alloy 20 buttweld fittings. The composition of the alloy 20 buttweld fitting is chromium, nickel, molybdenum, and copper offers excellent resistance to sulphuric acid, pitting, crevice corrosion and stress corrosion cracking. These fittings have a density of about 8.06 g/cm 3, hence they can resist extreme temperatures and high-pressure environments without deformation. Such a combination of strength and corrosion resistance makes Alloy 20 buttweld pipe fittings a very good option in high stress industrial applications that demand safety, durability and long service life.
Kalpataru Piping manufactures Alloy 20 buttweld pipe fittings under strict quality control and accuracy to suit the various requirements of the industry. These fittings come in standard sizes of 1/2 inch to 12 inch with wall thickness of up to 40 mm and even made to customized sizes as required by the project. Kalpataru Piping is dedicated to offering quality and corrosion resistant Alloy 20 fittings at reasonable prices, to provide quality service both in standard and specialized piping.
