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.

Process

Killed steel, with forgings, bars, plates, sheet, and seamless or fusion-welded tubular products with filler metal added. Forging or shaping operations performed by hammering, pressing, piercing, extruding, upsetting, rolling, bending, fusion welding, machining, or by a combination of two or more of these operations.

Heat Treatment

After forming at an elevated temperature, fittings are cooled to a temperature below the critical range under suitable conditions to prevent injurious defects caused by too rapid cooling, but in no case more rapidly than the cooling rate in still air. Heat treatment temperatures specified are metal (part) temperatures. Heat-treated fittings are to be treated according to paragraph 7 in Specification A960/A960M.

Elbows ASTM A324 WPB

Reference Documents



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:

Recommended type of pipe elbows:

Materials

  • Carbon steel: ASTM/ASME A234 WPB-WPC
  • Alloy steel: --WP 22-WP 5-WP 91-WP 911
  • Low temperature steel: ASTM/ASME A402 WPL 3-WPL 6
  • High performance steel: ASTM/ASME A860 WPHY 42-46-52-60-65-70
  • Stainless steel: ASTM/ASME A403 WP 304-304L-304H-304LN-304N

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.


Fitting specification, Standard and identification

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