Big diameter elbows

Big Diameter elbows

Big diameter elbow is curved connecting pieces that join straight lengths of pipe, commonly at a 90° or 45° angle, allowing obstructions to be avoided in plumbing, ventilation, welding, and automotive applications.

Usage:

Petroleum, chemical, power, gas, metallurgy.

Our pipe elbows are widely used in many industries, such as power generation, petroleum, natural gas, chemicals, shipbuilding, heating, papermaking, metallurgy and so on.

DOWNLOAD STANDARD

Even welding and smooth weld line, can be substitute for seamless tube after drawing and cold rolling.

ASME B16.9

This Standard covers overall dimensions, tolerances, ratings, testing, and markings for wrought factory-made buttwelding fittings in sizes NPS 1 ⁄ 2 through 48 (DN 15 through 1200).

Fittings may be made to special dimensions, sizes, shapes, and tolerances by agreement between the manufacturer and the purchaser.

ASTM A234/ SA234M

ASTM A234/ SA234M Standard specification for pipe fittings of wrought carbon steel and alloy steel for moderate and high temperature service.

These fittings are for use in pressure piping and in pressure vessel fabrication for service at moderate and elevated temperatures.



An elbow is a pipe fitting installed between two lengths of pipe or tubing to allow a change of direction, usually a 180° or 90° angle, though 45° elbows are also made. The ends may be machined for butt welding (SW) or socketed welding(SW) etc.

Most elbows are available in short radius or long radius variants. When the two ends differ in size, the fitting is called a reducing elbow or reducer elbow.

Elbows are categorized based on various design features as below:

Abrasion resistant elobw

SHS-self-propagating ceramic composite steel pipe and fittings, the new generation of wearable and corrosion resistant engineering pipeline, belongs to "863" Hi-tech Plan products.

It is the ideal wearable and corrosion resistant engineering pipeline, with wear resistance 15 times higher than common steel pipe, smooth inner surface, and favorable liquor resistance.

Pipe elbows

Butt Weld Pipe Fitting Bevel

  • All welded pipe fittings have bevelled end to allow for ease of welding.
  • This bevel allows for full penetration weld in most cases.
  • There are two types of bevels;
    Plain Bevel and Compound Bevel: according to the bevel of welding pipe fittings construction .
  • ASME B16.28, Buttwelding Short Radius Elbows and Returns
Industrial Processes: Bending, squeezing, pressing, forging, machining and more ANSI/ASME B16.25, Buttwelding Ends
ANSI/ASME B16.25 Standard covers the preparation of butt welding ends of piping components to be joined into a piping system by welding.

Application of pipe elbows:

Petroleum, chemical, power, gas, metallurgy, shipbuilding, construction, etc.

ELL & ELLS

  • A wing of a building at right angles to the main structure.
  • A right-angled bend in a pipe or conduit; an elbow.

Pipe elbows by radius and degree

We offer multiple bend pipes, all with different specs and operative requirements.

Short radius

SR Elbows have a Center-to-Face dimension of 1.0 X diameter usually includes three angles degree ( 45°,90°,180°).

Butt weld 5D pipe bend
Long radius

The radius of LR elbow curvature of is 1.5 times the diameter of the pipe, usally includes three degrees (45° ,90°,180°)

Reducing elbow

The reducing elbow eliminates one pipe fitting and reduces the welding by more than one-third.



Fitting specification, Standard and identification

There are different varieties of pipe fittings made of various materials and available in various shapes and sizes.
