The quality inspection process of ERW steel pipe includes on line nondestructive testing, metallographic examination, flattening, combustion destructive test and hydrostatic test. Evaluation process1, online nondestructive testing The detection arm of the testing station rotates and is placed on the longitudinal welded pipe production line.
At present, it plays an important role in the world of transportation pipes. 1 ERW 2 Manufacturing Process 3 Standard 4 Quality inspection process Electrical resistance welding Electric resistance welding (ERW) refers to a group of welding processes such as spot and seam welding that produce coalescence of faying surfaces where heat to form the
In the last stage of inspection, the pipe is checked visually and dimensionally by competent inspection engineer. He will ensure that pipe is meeting the code, standard, and specification requirements. Once the Inspection engineer cleared the pipe, it will mark as per the standard requirements & send for the packaging. ERW / EFW or HFW Welded Pipe Manufacturing Process
The ERW In Line uses phased array technology to inspect weld seam and the heat affected zone (HAZ) of electrical resistance welded (ERW) tubes. The head rotation capability allows each probe independent movement from 120 to +120 degrees for weld tracking.

Boomerang is a market leader in the production of ERW pipe for downhole casing and tubing applications. ERW pipe is produced by forming hot rolled steel coils into a cylinder and then welding the strip edges together. We produce or process ERW up to 9.625 outside diameter (OD) in
ERW steel pipe with weld performance equivalent to the base metal; can be used in place of seamless and UOE steel pipe Weld Inspection Technology Phased array ultrasonic flaw detection system can be applied across the whole length of welds and toughness can be tested using NDT.
Electric Resistance Welded Pipe. ERW (Electrical Resistance Welding) pipes are manufactured by cold forming of steel coil into a round cylindrical shape are used in various engineering purposes. ERW steel pipe is formed by rolling plate and welding the seam.
There are 3 welding typesERW (Electric Resistance Welding), LSAW (Longitudinally Submerged Arc Welding), and SSAW (Spirally Submerged Arc Welding) welding types. ERW pipe is a type of Resistance pipe stands apart from welded pipe and DC welded pipe
ERW Inspection Systems The AS 200E System inspects Electro Resistance Welded Pipe (ERW), including weld, body and Heat Affected Zone (HAZ). The system may be integrated for online or offline inspection, and can be set up using a variety of ultrasonic configurations, according to inspection requirements and site conditions.
Apr 24, 2001 · An in depth examination of electric resistance welding (ERW) weld nuggets as a quality control step in the manufacturing of high strength tube and pipe used for pressure applications has been a proprietary procedure for some manufacturers for several years.

Aug 27, 2013 · While this technology has application on all types of tube and pipe welding, of particular interest is its application to weld profile monitoring of ERW and HF welded tubes. Properly monitoring the height and shape of the weld bead allows an inference of the quality of the weld, thereby enabling real time detection of defects during production.
REvisual welding inspection Vasudevan1968 (Mechanical) 23 Jun 16 08:05 do we need to qualify branch weld (weld 'o' let to run pipe) full pen groove weld separately as per ASME B 31.3? which category this will be considered as whether fillet or butt joint as per ASME Sec IX for qualification? please share your valuable knowledge.
It is recommended to use high quality ERW pipe, with its seam weld line positioned around the 12 Oclock during installation, to minimize and decelerate grooving corrosion. It is also important to perform regular or routine inspection, on suitable intervals, determined by past experience.
The manufacture of electric resistance welded pipe. We next examine the basic steps necessary to produce electric resistance welded (ERW) pipe. Coil Feed Ramp. The coils are removed from storage and placed on the feed ramp (see Figure 4.1). Each coil
