 · Aside from providing lubricity between the product and the tooling, OD lubricant provides necessary cooling of the product and tools. Too little lubricant leads to excessively high temperatures that lead to abnormal material flow. Too much lubricant inhibits the reduction process, applying abnormal pressure to the tooling.

Lubrication is a key factor in the cold pilgering operation in terms of productivity as in most metal forming operations. This is due to several reasons. First of all, it preserves the surfaces quality of the tool and tube which is a highly important criterion for cold finishing processes. A bad lubricant increases the friction and accelerates ...

Cold Pilgering is a longitudinal cold roling process that reduces the diameter and wall thickness of metal tubes in one process step. There are two main facts to remember about the pilgering process: Pilgering, for one, is a cold working method that vastly strengthens the material structure. Second, with a reduced rate of 50-60%, it will reduce ...

The lubricants that are used today by Materials Technology AB in the cold pilger process contain chlorinated paraffins. Due to environmental, economic and health reasons, these lubrica ...

Two lubricants are normally used in the cold pilgering process, an internal lubricant between the mandrel and the tubing being drawn over it and an external one on the outside of the tubing, i.e. between it and the walls of the rolls. Often the same product can be used as both the internal and external lubricant in applications where small ...

 · Pilgering is a promising technique for fabricating advanced alloys such as oxide-dispersion strengthened (ODS) cladding (MA956 and 14YWT) suitable for producing tubing for reactor use. This project is using the lab-scale pilger mill located at the Pacific Northwest National Laboratory (PNNL). 2. BACKGROUND OF DEVELOPMENT OF PILGERING …

 · Cold pilgering is a seamless tube forming operation, which is widely used in manufacturing tubes made of hardly deformable alloys, including steels and alloys of copper, titanium and zirconium. More than 70% of cross-sectional reduction is possible in cold pilgering, compared with that in cold drawing [ 1, 2, 3 ].

evaluating the lubrication state in cold pilgering by hydrodynamic calculation of the oil film thickness of the lubricant. Carscallen et al. (1994) reported the design of a cooling system for cold pilgering with an optimized coolant nozzle. Tripp (1988) investigated the selection of the lubricant and process controls for cold pilgering.

Fluid Recycling Service (FRS) Pilgering Lubricants Blachford and Quaker Chemical manufacture synthetic non-chlorinated products used in tube drawing and pilgering operations. The unique film forming properties of these products provides excellent cooling in high speed transfer presses and progressive dies.

Cold pilgering is a rolling process in which the diameter and wall thickness of metal tubes is reduced. During this process, a large number of forming steps are completed to improve the roundness, stresses, homogeneity, and surface roughness of the tubes. SMS group's cold pilger mills are also suitable for forming difficult materials with a high cross section …
