DIN 2605 elbow is a pipe fitting that complies with the German Industrial Standard (DIN). The DIN 2605 standard specifically stipulates detailed requirements for elbow pipe fittings, including the size, tolerance, material, manufacturing process, inspection method and other aspects of the elbow. This standard is intended to ensure that the quality and performance of elbows meet specific engineering requirements and ensure the safe and reliable operation of the piping system.
DIN is a series of industrial standards developed by Germany's standardization organization, which has a wide influence in Europe and even around the world. These standards cover many industrial fields and provide unified specifications and basis for product design, manufacturing and quality control. DIN standards are known for their rigor and scientific nature, ensuring that products produced by different manufacturers have good interchangeability and compatibility in terms of size, performance, etc.
What is the DIN standard for elbows?
Elbows and Bends for use at Full service Pressure DIN 2605 standard specifies the design and dimensions of seamless and welded steel elbows and bends rated for the same internal pressure as the pipes to which they are to be connected (cf. clause 6). As the pressure rating of pipes is a function of their wall thickness, fittings have been classified according to wall thickness series (cf. table 1).

DIN 2605 Standard Field of Application
This standard specifies seamless and welded steel elbows and bends that are intended to be butt welded to pipes. Although the wall thicknesses specified correspond to those of 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 (cf, table 1 and clause 5).

How to calculate weight of 90 degree elbow?
The weight formula is W=0.0387 * S*(D – S) * R / 1000, the unit is kg/piece. What’s the meaning of each letter? Let’s explain to you.
W means Weight.
S means Thickness in mm.
D means Outside Diameter in mm.
R means Radius that LR=1.5D, SR=1D.
Now we take “90 Degree Elbow LR Seamless 6″ Sch 40 BW ASTM A234 WPB” as sample. From above diameter and thickness chart, we know the outside diameter is 168.3mm and thickness is 7.11mm. The weight will be 0.0387 x 7.11 x ( 168.3 – 7.11 ）x 1.5 x 168.3 / 1000 = 11kg/piece.
DIN 2605 Elbow Dimension
The size range of DIN 2605 elbows is DN15-DN1600. The following figure is the size table of DN15-DN150 (1/2"-6").

1)The pipe outside diameters given have been taken from series 1 in ISO 4200.
2) The wall thicknesses specified for series2,for nominal sizes up to DN1000,are in accordance with the normal wall thickness series given in DIN 2458.

How to Calculate the Correct Pressure Rating
The formula is P = (2TS/D), where P is pressure, S is allowable stress, t is the wall thickness, and D is outside diameter.
P = pressure
S = allowable stress
T = wall thickness
D = outside diameter
This formula calculates the pressure rating of a pipe by multiplying twice the hydrostatic design stress of the material by the product of the operating temperature multiplier and the ambient design factor.

Characteristics of DIN 2605 Elbows
Precise and Standardized Dimensions
The DIN 2605 standard precisely specifies the dimensions of elbows, including key parameters such as outer diameter, wall thickness, bending radius and angle. Elbows of different nominal diameters have clear and detailed standard requirements for each dimension.
Multiple Specifications Available
The elbows under this standard provide a variety of dimension specifications, covering a variety of options from small diameters to larger diameters. ZIZI can meet various size requirements.
Reliable Pressure Bearing Capacity
DIN 2605 elbows manufactured in accordance with the standard have undergone rigorous pressure testing and quality inspection and can operate stably and for a long time at the specified pressure level.
Various Anti-Corrosion Coating Options
According to different use environments and requirements, DIN 2605 elbows can be treated with a variety of anti-corrosion coatings, such as galvanizing, painting, etc. These anti-corrosion coatings can further improve the corrosion resistance of the elbows and protect the elbows from erosion by the surrounding environment medium.
