Specifications︰ 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
 Macro and Micro examinations of metallic materials (Including both photo macro & micrographs)
 Determination of percentage ferrite to ASTM E562
 Weld testing (complemented by our NDE availability)
We have close links with several other ILAC accredited laboratories and as such can sub-contract testing outside of our accreditation e.g. elevated temperature tensile testing, chemical analysis, HIC and SSCC corrosion tests etc.

Non Destructive Examination
To ensure compliance with specification, many of our bends undergo non-destructive testing. This can be as simple as a basic minimum wall thickness check or can involve a series of surveys using various means of fault detection.

We provides an in-house service through highly experienced operators based within our site and qualified to ASNT / PCN Level II (with procedures externally approved to Level III). This arrangement allows the flexibility we need to ensure our process is as efficient as possible.


Our available range of in – house NDE comprises;

■Magnetic particle inspection – standard format
■Magnetic particle inspection – fluorescent format
■Liquid penetrant inspection
■UT wall thickness survey
■UT straight beam lamination survey
■UT shearwave survey
■UT longitudinal seam weld survey
■Surface hardness survey
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.


Workmanship is initiated at every level. Every piece is examined and cross-examined. Non-destructive testing plays an important role in maintaining high quality. According to our customers bending specification, MIL 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
