project and construction presses for the production of pipes with JCO method
Aem3 s.r.l. It is the only company in the world able to provide all the line for the construction of pipes with the J-C-O method. As described below, for the production of these pipes, it is necessary a complete line of various installations. Each line is planned according to the production requirements of the customer. The normal production of pipes is included in a range of diameters: from 219 mm. to 1219 mm. - Thickness: 6 mm. to 60 mm. - Lengths: up to 13 meters - material: stainless steel (AISI), duplex steel, steel SUPERDUPLEX. Each system must be designed according to the product range and the size of the planned orders, what is critical to have a functionality and a professionalism in line with market requirements.

CHAMFERING LATERAL SHEET METAL
The sheet metal cut to size (length equal to the final length of the pipe and a width equal to the development of the required diameter of the pipe) must be provided with chamfers on the sides as legislation, so that when it is bent for the construction of the pipe, creating the correct space for final welding. According to the production, this system can be performed with processing for "planer" or by machining with milling machine. AEM3 s.r.l. hand knowledge of the best manufacturers of these machines and may accompany the customer to the correct selection.

FIRST BENDING FOLD SHEET METAL OR PIPE INVITATION
After the CHAMFERING LATERAL, the sheet metal is ready to be bent.
Before the total bending of the pipe is essential to carry out the first bend on both sides of the sheet, so that the subsequent bending guarantees correct geometric tolerances circularity of the pipe.
For this work AEM3 s.r.l. It proposes two different systems of its production:
- Press invitation "single", ideal for small / medium production
- Press invitation "double", ideal for large productions. -
SHEET METAL BENDING
After the first bend of invitation proceed performing the various bends until the pipe with the half-closed edges. Bending changes depending on many reasons: the diameter in production (ability to perform the complete bending of certain diameters and for larger diameters need to perform bending, turn the pipe, and run bending on the opposite side) - the sheet thickness (minor bending step by increasing the thickness) - length of the pipe. According to the production required of our folding machines are dimensioned and manufactured with power push and correct size for use.
-
SPOT WELDING PIPES
After performing the pipe bending, keep closed the edges, so you can after provide for the welding of the pipe: TIG - MIG - MAG - SUBMERGED ARC. For this operation the plants to choose between products from AEM3 s.r.l., will mainly be indicative based on production / pipe diameter, that will do: production SMALL-MEDIUM-LARGE.
-
WELDING
After the correct bending sheet metal and spot welding the pipe must be welded along its entire length, filling the space between the welding chamfers initially performed. Welding machines and welding systems are of various types and they are selected by the customer according to their own supply and the applicable regulatory requirements. AEM3 s.r.l. hand knowledge of the best manufacturers of these machines and may accompany the customer to the correct selection.
-
CALIBRATING
The calibration process is used to make pipes with circularity tolerances correct with international standards. The pipe, after always tends to flatten that welding processes so you have to bring it back to the correct conditions of circularity. In addition to flatten that the pipe heated by the welding process is retort losing its linearity must also then be straightened. In addition to the welds to deform the pipe can also be thermal hardening treatments, in that case, the adjustment process must also be done after the thermal treatment. The calibration presses must make the circular tube and right, ready for subsequent processing. Together the presses Aem3 s.r.l. It can also provide the calibration of mold that can be of various types according to the characteristics of the presses on which they are mounted.

FACING SIDES PIPE
After calibrating and straightening pipe, you have to execute the facing. By facing execute a machining on 2 pipe heads, performs the correct final size, the straighten and do an outer bevel (chamfer of the same size that was run longitudinally). The outer bevel which allows the pipe the final stage of installation can be joined to other pipes, for laying in work. AEM3 s.r.l. hand knowledge of the best manufacturers of these machines and may accompany the customer to the correct selection.
-
HYDRAULIC LEAK TEST
After finishing the working pipe, according to technical standards and requirements of the end customer, a hydraulic weld tightness test is performed. For the execution of hydraulic test Aem3 s.r.l. has designed and constructed two different systems, a plant for large productions (when tests are required on 100% of production) and a plant for small / medium production if the tests are performed only random. The hydraulic test is performed by entering into the pipe a quantity of water treated and apply an internal pressure of up to 1300/1500 Bar and make sure the seal weld.
