Product Description

Induction Bending  is a controlled means of bending pipes through the application of local heating using high frequency induced electrical power. to create a narrow, circumferential, heated band around the material to be bent. When the appropriate temperature is reached, the material is pushed forward through the coil at a consistent speed and temperature while a bending moment is applied. After the material passes through the coil, it may be cooled (quenched) by forced air or water spray, or it may be allowed to cool naturally at ambient temperatures.

Originally used for the purpose of surface hardening steels, induction technology when used in pipe bending consists basically of an induction coil placed around the pipe to be bent. The induction coil heats a narrow, circumferential section of the pipe to a temperature of between 850 and 1100 degrees Celsius (dependant on the material to be formed). As the correct bending temperature range is reached, the pipe is moved slowly through the induction coil whilst the bending force is applied by a fixed radius arm arrangement.

As the bending occurs, the adjacent area forward of the heat band is water or air quenched (or may be allowed to cool naturally) thereby allowing the cool material to either side of the ‘heat band’ to retain the integrity of the original material as best as possible. This means of distortion control provides excellent dimensional accuracy and repeatability.

Achieved tolerances when forming induction bends are to some extent governed by the materials in hand and the required format of the finished product however the following are the minimum standards to which Induction Pipe 

Although induction bending produces excellent results as far as physical properties are concerned, it must be noted that there are two important considerations required – firstly the reduction in wall thickness at the outside (extrados) of the bend and secondly the degree of ovality which is present.


The induction pipe bending process uses induction heating to produce highly accurate bends. The quality of induction bends is superior to the elbow fitting. Hydro burst tests show that spools with induction bends fail in the straight pipe and not in the bend, whereas in comparable elbow-based systems the elbow (inside radius) is always the first to burst. Stress calculations confirm this. The natural tendency to have a thicker inside wall thus proves to be advantageous and ensures that the bend exceeds the strength of the straight pipe. Many companies have exclusively chosen equipment for their induction bending.

Our Bending is capable of providing the following tests and more.

X-Ray, Heat Treatment, Stress Relieve, Liquid Penetrate Testing, Brinel Hardness Testing, Magniflux Testing, Ultra-Sonic Testing, Magnetic Particle Testing, PMI (Positive Material Identification), Elemental Analyzer, Hydro Test.

Destructive Mechanical Testing
Testing can be carried out to American e.g. ASTM & API, European e.g. BS EN & DIN and to individual client standards e.g. Shell DEP 31.40.20.33, DNV OS F101 & BP GIS 43 – 317 amongst others
We are happy to make arrangements for witnessing of testing by statutory inspection bodies (e.g. Lloyds Register, Det Norske Veritas and Bureau Veritas) as well as by clients and client representatives, ensuring that transparency & confidentiality is always maintained
Under our ILAC/CNAS Accreditation the following tests can be carried out
 Tensile testing (ASTM and BS EN)
 Impact testing (ASTM, BS EN & IZOD) from ambient to – 196° C
 Hardness Testing (Vickers and Brinell)
 Corrosion tests on Duplex and Stainless steels to ASTM G48 – A

Post Bend Heat Treatment

A feature of induction bending pipework is that due to the heat input allied to the stresses formed during process, mechanical properties may be altered – sometimes significantly.

The majority of materials we bend, particularly high yield carbon & duplex type steels etc. require a full body furnace heat treatment after bending in order to either restore or, as is often the case, enhance mechanical properties. Through our local sub contractor we are able to offer a variety of heat treatments including the following;

Normalise
Usually applied to carbon steels such as ASTM A106 Gr. B, A333 Gr. 6 & API 5L X52, this process includes a set time at temperature with a still air cool to ambient outside the furnace atmosphere

Normalise & Temper
Commonly associated with materials containing a higher level of chrome e.g. ASTM A335 P11 & P22 etc. Once complete, the normalise process (as above) is followed by tempering for an extended time at a lesser temperature, again with a still air cool to ambient

Quench & Temper
Intended for high yield materials e.g. API 5L X65, the material is held for a time at temperature then rapidly quenched in a cooling medium to provide a hardening action. Once complete, the quench is followed by tempering at a lesser temperature, this time with a still air cool to ambient

Solution Anneal
Applied to stainless & duplex steels such as UNS S31803 & UNS S32760, the material is held at an elevated temperature for the required time before rapid cooling in either air or water. No secondary heat treatment is usually required with this process.

Principle of induction bending

Induction bending uses inductors to locally heat steel by induction. This results in a narrow heat band in the shape to be bent. The shape is firmly held by a clamp at the desired radius, which is mounted on a free pivoting arm. The shape is is pushed through the inductor by an accurate drive system which causes the hot section to form the bend at the set radius. The bent part is then cooled by water, forced or still air to fix the bend shape.

The bending process is continuous and highly automated from start to finish.

Areas of application

Induction bends find their way in the following industries:
•Petrochemical
•Chemical
•Power Generation (conventional and nuclear)
•Oil and gas (incl. expansion joints)
•Compressor and pump stations (fluids and gasses)
•Offshore
•Shipbuilding
•Construction



Common material groups are:


Carbon steels Low alloyed steels
High alloyed steels

Fine grain steels

Stainless steels Austenitic
Martensitic

Duplex

Special alloys


Samples of steels routinely bent for various industries are:

Offshore Duplex/Super Duplex
Power P91 / P22 / WB36 / P92
Pipe line API 5L X52 / X65 / X70 / X80 – X100
Petrochemical A106 Grade.B / Grade.C / P1/ P9, A312TP304, TP316
Other Aluminium, Titanium


Major advantages of induction bending are:
•Cost efficiency. Straight material is less costly than standard components (e.g. elbows) and bends can be produced faster than standard components can be welded.
•Elbows can often be replaced by larger radius bends, reducing friction, wear and required pump capacity.
•Induction bending reduces the number of welds in a system. ◦No welds at the critical points thanks to the tangents.
◦Less non-destructive testing, saving cost.

•Induction bends are stronger than elbows with uniform wall thickness
•Stock of elbows and standard bends can be greatly reduced.
•Straight pipe is more readily available than elbows, reducing time to market
•Bends can be made from the same base material as the straight pipe.
•Induction bending does not need bend dies or mandrels. A simple clamping/ inductor set covers a wide range of radii and wall thicknesses
•Induction bending is a clean process. No lubricants necessary.

Critical piping is designed with very special care and the material selected for such piping is subjected to withstand high pressure and high temperature.

Critical piping mainly consists of following:
•Power Generation: Main Steam, Hot Reheat, Cold Reheat, Feed Water & Bypass Lines etc,
•Refinery & Petrochemicals: High temperature and high pressure piping associated with Hydrocracker, Hydrogen, FCCU, CRU Plant etc.

These Piping often expand due to high temperature, thus need to have built in flexibility. Such piping systems are governed by guidelines and mandatory requirements.
