BUTT WELDED PIPE ELBOW

Steel pipe elbow is a key parts in a piping system for to change the fluid flow direction. It is used to connect two pipes with same or different nominal diameters, and to make the pipe turn to a certain direction of 45 degree or 90 degree.

For industrial pipe elbow, the connectin end type is butt weld, according to ANSI B16.25. Butt welded can described butt welding, buttweld, bevel end. BW

ELBOW TYPE

Elbow could be ranged from direction angle, connection types, length and radius, material types.

Classified by Direction Angle

As we know, according to fluid direction of the pipelines, elbow can be divided into different degrees, such as 45 degree, 90 degree,180 degree, which are most common degrees. Also there has 60 degree and 120 degree, for some special pipelines.

For 90 degree  elbow, also described 90d elbow, or 90 deg elbow.

What is Elbow Radius

The elbow radius mean curvature radius. If the radius is the same as pipe diameter, it called short radius elbow, also called SR elbow, normally for low pressure and low speed pipelines.

If the radius is larger than pipe diameter, R ≥ 1.5 Diameter, then we call it a long radius elbow (LR Elbow), applied for high pressure and high flow rate pipelines.

If radius more than 1.5D, always named bend.  elbow bend pipe fittings. Such as 2d elbow, 2d bend, 3d elbow, 3d bend, etc.

Classification by Material

Carbon steel, also called mild steel or black steel. Such as ASTM  A234 WPB

Shape Type

Can be equal elbow or  Reducing elbow

ELBOW SURFACE

Sand Blast

After hot forming, we arrange sand blast to make the surface to be clean and smooth.

After Sand blast, to avoid get rust, should do black painting or anti-rust oil, Hot dip galvanized (HDG) , epoxy, 3PE,  vanished surface, etc. That is depend on customer's request.

HEAT TREATMENT

1. Keep sample raw material to trace.
2. Arrange heat treatment as per standard strictly.

MARKING

Various marking work, can be curved, painting, lable. Or on your request. We accept to mark your LOGO.
