ASME/ANSI B16.9 45 degree elbow have same function and usage with 90 degree elbow, but the dimension and shape is half of it. There is long radius only. The material can be carbon steel, alloy steel and stainless steel. It is quite used in multiple industries such as chemical, petroleum, electronic, fluid power, shipyard, oil and gas.
There are 3 types that socket weld elbow, butt weld elbow and threaded elbow.ASME/ANSI B16.9 45 degree butt weld elbow is common used due to the large range of outside diameter and thickness.
Butt weld Fittings
Buttwelding Fittings are used in a piping system to change direction or function of media, to branch off, reduce pipe size or attach auxiliary equipment. They are availbale in multiple types as elbow, tee, cap, reducer, Lap joint stub end and oelt, that produced in cold and hot forming based on ASTM A403 and ASTM A234 specification. We usually make the end bevelling for welding easily on site.
Before delivery, we will pack the 90° elbow purchased by the customer with length, wall thickness and Angle. Those less than 8 inches will be packed in wooden cases, and those larger than 8 inches will be packed with wooden brackets.
ASME B16.9 Standard covers overall dimensions, tolerances, ratings, testing, and markings for factory-made wrought buttwelding fittings in sizes NPS 1 ∕ 2 through NPS 48 (DN 15 through DN 1200). It covers fittings of any producible wall thickness. This standard does not cover low pressure corrosion resistant buttwelding fittings. See MSS SP-43, Wrought Stainless Steel Butt-Welding Fittings.
Special Fittings
Fittings may be made to special dimensions, sizes.shapes, and tolerances by agreement between the manufacturer and the purchaser.
Codes and Regulations
A fittings sued under ASME Boiler and Pressure Vessel Code (BPVC), the ASME code for pressure piping, or a governmental regulation is subject to any limitation of that code or regulation. It includes any maximum temperature limitation or rule governing the use of material at low temperature.
