What is the purpose of a 90 degree elbow?
The function of a 90° elbow is to change direction or flow in a piping system. Elbows are split into three groups which define the distance over which they change direction, expressed as a function of the distance from the centre line of one end to the opposite face.
What is the size range of the elbow?
Our program includes seamless butt welding fittings from 1/2 in. to 12 in. and welded butt welding fittings from 1/2 in. to 24 in. The schedule range covers 5S to Schedule 160.
Butt weld keeps better strength, good for high pressure or high temperature pipelines. So it is used when a welded joint with strength not lower than that of the base metal itself is needed.
What’s the material of the steel elbow?
Monel, Nickel, Inconel, Hastalloy, Titanium, Tantalum, Stainless Steel, Alloy Steel, Carbon Steel, Cupro-Nickel 90/10 & 70/30, Stainless Steel ASME / ASTM SA / A403 SA / A 774 WP-S, WP-W, WP-WX, 304, 304L, 316, 316L, 304/304L, 316/316L, DIN 1.4301, DIN1.4306, DIN 1.4401, DIN 1.4404
What does B16 9 mean?
The ASME/ANSI B16. 9 specification covers the dimensions and the tolerances of carbon and alloy butt weld fittings. The MSS-SP 43 specification integrates ASME B16. 9 to cover stainless steel and nickel alloy pipe fittings
