Protection caps with straps PÖPPELMANN has expanded its Kapsto ® range of standard products. The new GPN 696 protection cap with retaining tab reliably prevents banjo screws from being damaged or contaminated. Compared to other protection caps, the GPN 696 series has a number of beneficial distinctions. Whether during transportation or This is due to the GPN 696’s retaining tab. It continues to hold the banjo screw tight after the protection cap has been removed from the threads, preventing the screw from coming loose from the ring fitting. As a result, each banjo screw can be reliably installed in the vehicle or pipe system. The perforated retaining tab of the GPN 696 opens at the predetermined breaking point

from stock, and a team of application engineers develops special solutions based on customer specifications, such as combining protection with assembly functions.

The GPN 696 can be removed just as easily and with low abrasion by gently pulling, which splits the perforated retaining tab at the predetermined breaking point. The GPN 696 series also saves time. Its flexible TPE material (thermoplastic polyester elastomer) and internal clamping points ensure fast and simple assembly. Produced in sizes M 10, M 12, M 14 and M 16 for banjo screws, the new standard Kapsto products are produced in yellow. More than 3,000 different plastic caps and plugs can be delivered

At the same time, it simplifies assembly of banjo screws and pipes.

Induction tube hardening and tempering with EloMat TM multi-zone technology

input material and usually does not exceed 2mm/m; sometimes it is even better. SMS Elotherm offers to customers complete quench and temper system solutions with comprehensive process expertise.

A significant feature of modern tube hardening and tempering systems is the high homogeneity of the tempered structure, with uniform Rockwell hardness (variation ±1 HRC or better) measured over the entire tube length. Due to the very short heating times achieved with induction heating, surface decarburisation does not occur and scale formation is minimal compared to furnace hardening. The negative effect of tempering brittleness with various material grades that are preferably used for hardening and tempering does not occur with induction technology. Precise process management with high reproducibility in conjunction with specific material handling during transport, induction heating with controllable multi-zone technology, effective quenching and a special cooling bed allow a high degree of tube straightness to be achieved after hardening and tempering. The straightness corresponds to that of the

INNOVATIVE solutions from SMS Elotherm offer higher flexibility than conventional furnace systems for induction hardening and tempering of long products, especially with small batch sizes. In just a few minutes, tube hardening and tempering lines can be ramped up or down and reconfigured for the next material batch. In situations where materials of different sizes and batches with different steel grades need to be hardened and tempered at different temperatures on a daily basis, output capacity can sometimes be increased by more than half compared to hardening and tempering in a conventional furnace. In induction tube hardening and tempering systems, thermal energy is induced directly in the material to achieve maximum throughput for the entire range of tube products. This avoids lost time due to conductive heating, which requires longer process times.
