Your Premier DIN 86090 ELBOW Manufacturer and Supplier

DIN 86090 is one of the DIN standards copper nickel pipe fittings for shipbuilding.

DIN 86090 elbow can be produced by shihang.

Shihang DIN 86090 elbow can suffer 10 bar and 14 bar pressure. If you want to use DIN 86090 elbow in high pressure, the thickness need be thicker.

Shihang DIN 86090 has two types, one is seamless DIN 86090 elbow and the other is seam welded DIN 86090 elbow.

DIN 86090 elbow can change the sea-water pipeline’s flow direction.

There are two kinds of elbow in DIN 86090, short radius and long radius.

Long radius DIN 86090 elbow is most common.

The degree of DIN 86090 elbow is 30°,45°,60°,90°.

    The difference bewteen DIN 86090 Elbow Long Raidus and DIN 86090 Elbow Short Raidus


    The DIN 86090 long radius elbow means that the radius of curvature of the elbow is 1.5 times the diameter of the pipe; if it is more than 1.5 times, it is the bend.

    A short radius elbow means that the radius of curvature of the elbow is equal to the diameter of the tube.

    D is the diameter of the elbow.

    Long radius elbows are commonly used. Generally, the default is also a long radius elbow.

    Where the pressure is high or the flow rate is high, a long radius DIN 86090 elbow is used. If the resistance of the solid conveying pipe is strict, a larger radius elbow is used.

    Short radius DIN 86090 elbows are generally used in low-pressure fluids or where elbows are limited during installation.

    Long-radius elbows are preferred if there are no conditions or are not specified in the contract.

    Intuitively, the short radius elbow is much shorter than the long radius elbow, and the bend radius of the elbow is very short.

    The use of long radius in pipelines is common, while the use of short radius is relatively small. This is due to the special construction of the two.

    Long-radius elbows have a more uniform curvature and a higher compressive capacity than short-radius elbows. high.

    Butt weld elbows are generally long radius elbows.

    Short-radius elbows are generally suitable for pipes with relatively low pressure and resistance, and pipes containing solid particles or particles that are easy to produce crystals, two-phase flow pipes, pipes requiring a certain flexible pipe, and low-pressure drop, are prone to vibration. Pipes should generally not use short radius elbows.
