Tube mi l ls & rol l forming l ines

Three-roll cold forming for finned tube rolling ESCOFIER is a specialist in cold rolling profiles onmechanical parts dedicated to the automobile market. The company’s knowledge of this technology and its associated machines are well known by major OEMs forming threads and splines on shafts utilised in gearboxes and transmission systems. For example, the machine is able to stop and recover the finning process on applications such as bent tubing.

The fully electric Triroll machine is available in two sizes, and with a range of options, offering the same modular concept as the Flex series. Escofier process engineering teams have contributed to offer, along with the Triroll machine, an optimal disk assembly concept, assuring higher quality and tool life. The specific design and development allows aluminium tube manufacturers the opportunity of saving up to eight per cent of the material cost by increasing the fin depth.

As a result of its long experience, and having successfully developed its Flex Quatroll, a cold rolling machine dedicated to thin wall stainless tubes with low fins capable of working from 5 to 6m per minute, the Escofier product line has now been expanded with the launch of the new three-shaft Triroll series machines, specially adapted for rolling finned tubes utilised in heat exchangers. Designed to cold roll fins on steel, copper or even aluminium tubes from 10 to 80mm in diameter, the three numeric axes supplied on the base version, and the various options available, assure a simple use of the Triroll.

Line for small diameter, heavy wall thickness pipe

MYUNG Jin Machinery has delivered its first ERWpipemill line for producing pipe

with heavy wall thickness, particularly for high precision automotive products.

With annual production capacity up to 47,000 tons, the new plant has been producing tubes from 27.2 to 60.3mm diameter, and wall thickness from 5.5 to 11.2mm. As a second project, Myung Jin has been awarded a contract for the supply of a high performance pipe mill line for producing pipe of OD 101.6mm and wall thickness of 12.7mm, from pipe manufacturer Seah Steel, for its requirement of API pipes. Based on the high durability of each stand and shaft, the double edge forming system enables the mill line to produce pipes with heavy wall thickness of sch. 140. The complete line will be supplied along with finishing equipment such as straightening machine, end facing and chamfering machine, and hydrostatic tester.
