{"id":89,"count":23,"description":"This single-layer, internally hardened pipe is ideal for hydraulic and pneumatic conveyance of slightly abrasive materials. The wear resistant pipe and elbows are internally hardened up to 45 HRC, with hardness decreasing linearly from the inside to the outside. Customization is possible with these hardened pipe solutions, including the use of manganese cast elbows and special tube shapes. The Esser 400 series of wear resistant pipe has a service life of 2 to 3 times that of conventional steel pipes.\r\n\r\nThis hardened steel pipe system is ideal for applications requiring moderate abrasion resistance alongside structural flexibility. With an internally hardened surface of 45 HRC, these wear resistant pipes provide excellent wear protection against slightly abrasive materials.\r\n\r\nIdeal uses include:\r\n
