SECTION BENDING PIPE

Pipe and tubing is also known as HSS (hollow structural steel), just like square and rectangular tubing, since it is hollow.

CHS Steel / STEEL PIPING

W24S-180 profile bending machine bends Φ168mm steel pipe in Malaysia.

CHS MEANING ‘CIRCLE HOLLOW SECTIONS’

Of all the steel hollow sections, the circular hollow section came first. The CHS section is a common feature in a wide variety of structural steel operations and has a lot of construction and mechanical uses. The consistent and clean lines of steel CHS make this circular tube a very aesthetic choice in many building designs.

CHS steel is popular for the construction of handrails, balustrades, and scaffolding. Other purposes include sign poles, columns, fences, and architectural features such as bending steel staircases. CHS can be fine-controlled and internally scarfed. This allows the tube to be suitable for mandrel bending.

Pipe and tubing is also known as HSS (hollow structural steel), just like square and rectangular tubing, since it is hollow.

Few examples of pipe bending

  • Bending of round tubes from Ø 3 mm up to Ø 500 mm
    Press bending
    Small radius elbow (min. 1.25 x ND)
    Elbows for general industrial applications.
    Serpentine for heat exchanger. Flat, cylindrical, conic, bended tube bundles, …
    Elbow for pneumatique conveying
    Railings, handrails and tubular arched portal
    Tubular safety barriers
    Exhaust pipe elbow
    Tubular handrail and baserail for balanced staircase.
    Small thickness pipe elbow
    Industrial facilities (chemical, petrochemical, pharmaceutical, food, etc.)
    Agricultural machinery and equipment
  • Railways, naval, military, nuclear and energy sectors
  • Metallic construction
    Metallic parts furniture manufacturer
    Building ironwork
    Automotive equipment and construction machinery
    Manufacture of safety and protective equipment
    Boiler manufacturer, heat production, cold production
    Pneumatic conveying systems

Depending upon your unique project requirements, BIT pipe bending machine may be performed on a variety of materials, including carbon steelstainless steelaluminumtitanium, and copper.

Round tube lends itself well to bending because of the symmetry of the part and because, with the proper tubing, the part can be encapsulated well to avoid ovality or other distortion. Generally speaking, tighter bends are more difficult in round tube bending; similarly, the thinner the wall, the more difficult the bend. However, with the correct tooling, machinery, and procedures, excellent quality can be achieved even with tight-radius, thin-wall round tube bending.

Bending Pipe & Round Tube Circular Hollow

BIT series profile bending machine can bend all types of pipe and tubing including aluminum, stainless and carbon steel. We even bend specialty materials such as copper, zirconium and titanium.

Pipe and tubing are specified in different ways. Pipe is NOT called out by the OD size of the material and is not called out with an easily identifiable thickness.

Nominal Pipe Size Information

BIT provides detailed information on nominal pipe size and pipe schedules and sets out a complete table of schedule 40 and schedule 80 thicknesses & weights.

Like square and rectangular tubing, round tubing and pipe can be bent with virtually every bending process BIT series section bending machine have available in our shop. Processes include draw bending, roll bending, increment hot bending, increment cold bending and induction bending. The only exception is the plate roll.

W24s series section bending machine can bend all types of pipe and tubing including aluminum, stainless and carbon steel. We even bend specialty materials such as (zirconium and titanium). Carbon pipe (mill produced) is classified as ASTM A53 (most commonly) resulting in a yield point (psi) of 30,000 minimum for grade A and 35,000 for grade B. Carbon tubing (mill produced) are most commonly classified as ASTM A500B resulting in a yield point (psi) of 46,000 minimum for Grade B.

Tubing and pipe can be used in virtually any application but are most commonly used as railings, recreational products (play grounds, bike racks, goal posts), industrial products (boiler tubes, heat exchangers, piping systems) and curved members of canopies and awnings.
