Rajendra Pipe Fittings is a well-known manufacturer, supplier, and distributor of ASTM A403 Gr. WP 316/316L Buttweld Fittings. Stainless steel grade 316 contains added molybdenum content, which enhances the alloy’s improved corrosion resistance, particularly for general corrosion like pitting and crevice corrosion in chloride environments. This grade is an austenitic stainless steel grade. It is one of the most commonly used alloys. This material can be used in applications such as sinks and kitchenware, as well as in the brewing, food processing, dairy and pharmaceutical industries amongst others. Stainless Steel 316L is generally used in heavier gauge applications than standard ASTM A403 because of its improved weld ability. The ASTM A403 Buttweld Fittings are used in various industries ranging from basic industries such as Sugar, Paper, Textile, Dairy, and Engineering to more complex such as Oil & Gas, Petrochemical, Power Generation, Chemical & Fertilizer, and Nuclear Industries. Our Stainless Steel flange products include threaded flange, slip on flange, socket weld flange, weld neck flange, blind flange, lap joint flange, plate flange. These buttweld fittings are available in different sizes ranging from 1/8” NB to 36” NB as well as in custom sizes as per our customers demand. UNS S31600/S31603 Buttweld Fittings is also a martensitic Stainless Steel.
To ensure the high quality of the products we, at Rajendra Pipe Fittings perform various kind of tests on our products. The tests include Hydrostatic testing or Ultrasonic examination, eddy current testing, NDT and also chemical and physical property inspection.
