Seamless Carbon Steel Pipe Fittings Equal Tee With Standard DIN2615

 

The equal tee pipe fitting means the diameter of the tee is same to the main pipe. This is one of the types of pipe fitting. The tees fall in two categories, i.e. equal tee or unequal tee. According to this there are various shapes also like T shape,

Y shape and based on this the product is manufactured.Equal Tees, Reducing Tees and Lateral Tee special grade tees are widely supplied

to many industries such as power generation, petrochemical, shipbuilding, paper manufacturing, chemical, pharmaceutical, and fabrication.

DIN 2615 Tee with Type A and B confirming to Dimension B16.9 and B16.28 including Equal Teel, Unequal Tee, Seamless Tee, Welded Tee etc.

Steel butt-welding pipe fittings Tees with reduced pressure factor

 

This standard specifies seamless and welded steel tees that are intended to be butt welded to pipes. Although the wall thicknesses specified correspond to those the pipes, these fittings do not permit operation at the same internal pressure as the pipe welded on, i.e. they have a reduced pressure factor.

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.

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
