1.5D 3D 5D 6D 8D 10D Carbon Steel Pipe Fittings Black Return Bends with SCH40 SCH80


3D or 5D Pipe Fittings are always use for pipeline connection, the difference is the radius. it can be divide to 3D,5D,6D,7D,10D etc.

3D pipe bending is a pipe bend that the bend radius is 3 times the pipe outside diameter. The RADIUS of a 5D pipe bend is actually what is 5 times the nominal diameter. So if you had a 10″ diameter pipe, the radius of the centerline of the bend would be 50 inches.

Larger numbers have smoother curves. Smoother curves are often used for applications with higher pressure, abrasion or corrosion.

Features /Characteristics

1. Most of the pipe fittings are used for welding, in order to improve the welding quality, the ends are beveled, with a certain angle and a certain edge. This requirement is also relatively strict, the thickness of the edge, the angle and the deviation range,Standard of ANSI B16.9/DIN2501 regulations has specific it clearly. The surface quality and mechanical properties are basically the same as the pipe. For the convenience of welding, the steel grade of the pipe fittings and the pipes to be connected is the same.


2. All pipe fittings must undergo surface treatment, and the oxide scales on the inner and outer surfaces are sprayed off by shot blasting, and then coated with anti-corrosion paint.

Reference Standards

ASME B16.9 Specification for Butt Welded Fittings

ASME B16.9 specification is designed for butt welded fittings applied in industrial construction pipelines. Including elbow,

tee, cross, cap, reducer, and etc.


Standard Scope

The standard includes specifications of NPS 1/2 to NPS 48 (DN15-DN1200) factory-made wrought butt-welded pipe fittings

overall dimensions, tolerances ratings, test methods and markings.


Special Fittings

Special fittings here refer to special sizes, forms and tolerances that agreed between buyer and manufacturer.


Fabricated Fittings

Fabricated laterals and other fittings by circumferential or intersection welds are considered pipe fabrication

could not apply this standard.


Units under ASME B16.9 shall be stated in both SI (Metric) and U.S. Customary units. Designation for size is NPS.


Reference Standards

It is not considered practical to identify the specific edition of each standard and specification in the individual references.

A product made comply with a prior edition of referenced standards and in all other respects conforming to this standard

will be considered complied.

FAQ/ Customer Question and Answers

Q: Customer asked for butt weld fittings in A105:

A: Most common carbon steel buttweld fitting material is A234WPB. It is equivalent to A105 flanges,

however there is no such thing as an A105 or A106 butt weld fitting A106 Gr.B is for pipe grade.

The A234WPB fittings are made from A106GR.B pipes. A105 is a material from Bar forged to

be High pressure Fittings or Flange


Q: Customer requests “Normalized” butt weld fittings:

A: This is also a misconception since flanges are available in A105 and A105 N, where N stands for normalized.

However, there is no such thing as A234WPBN. Manufactures normalize their butt weld fittings was considered

that normalized heat treating process was done, Especially for the elbows and Tees Customer needing

“normalized” butt weld fittings should request WPL6 fittings which are high yield and are normalized as a standard procedure.


Q: Customer forgets to mention pipe schedule:

A: Buttweld fittings are sold as per pipe size but pipe schedule must be specified to match the ID of the fitting to

the ID of the pipe. If no schedule is mentioned, we will assume a standard wall is requested.


Q; Customer forgets to mention welded or seamless butt weld fitting:

A: Butt weld fittings are available in both welded and seamless configuration. A seamless butt weld carbon steel

or stainless-steel fitting is made of seamless pipe and is generally more expensive. Seamless pipe fittings are

NOT common in sizes bigger than 12”. Welded pipe fittings are made of ERW welded carbon steel or

stainless-steel pipe. They are available in sizes ½” to 72” and are more affordable than seamless fittings.


Q: What does Short Radius (SR) or Long Radius (LR) means?

A: You will often hear SR45 elbow or LR45 elbow. The 45 or 90 refers to the angle of the bend for buttweld fitting

to change the direction of flow.A long radius elbow (LR 90 Elbow or LR 45 elbow) will have a pipe bend that

will be 1.5 times the size of the pipe. So, a 6 inch LR 90 has bending radius that is 1.5 x nominal pipe size.

A short radius elbow (SR45 or SR90) has a pipe bend that is equal to the size of the fitting, so a 6” SR 45

has a bending radius that is 6” nominal pipe size.


Q: What is a 3R or 3D elbow pipe fitting?

A: First, the terms 3R or 3D are used synonymously. A 3R butt weld elbow has a bending radius that is

3 times the nominal pipe size. A 3R elbow is equal to 3D Elbows
