ESSER TWIN 700 BRACKET PIPE In free-standing or free-hanging shaft pipelines, sections of the pipeline are installed between “bracket pipes”. These are positioned in the shaft on the basis of a static weight calculation. ESSER TWIN 900 COMPENSATOR PIPE WITH STUFFING BOX These pipes compensate for length differences caused by thermal expansion. They consist of two pipes with different diameters that interlock. The stuffing box prevents the conveying material from leaking. ESSER TWIN 900 REDUCER The compensator pipe has increased the diameter of the pipe. The diameter is returned to the size of the pipe by reducing it. The pressure load increases in the direction of the smaller diameter. ESSER TWIN 900 reducers are able to compensate for these loads. ESSER TWIN 900 OUTLET PIPE The pressure and wear load caused by the reduction in diameter of the reducer has an effect on the downstream pipe. The inlet area of the following pipe is subjected to increased stress as a result. This area is often reinforced with ESSER TWIN 900 material. ESSER TWIN 700 STRAIGHT PIPE Once the flow rate in the pipe has normalized, two-layer pipes with a hardness of 63 HRC but smaller wall thickness can be used. They are economical and reliable. These pipes have a much longer service life compared to ST52 pipes. ESSER TWIN 700 TRANSITION PIPE Depending on the design of the elbow (thick-walled with a higher wear layer), it may have a larger outer diameter and require a different flange size. A transition pipe with different flange sizes is used to create the connection between the shaft pipeline and the elbow. ESSER TWIN 900 ELBOW The change in direction of the conveyed material leads to additional wear. The conveyed material collides with the outer radius of the inner bend. ESSER TWIN 900 elbows have a highly wear-resistant cast insert with a thicker wall in the outer radius, which counteracts the heavy friction and impact wear. ESSER TWIN 900 OUTLET PIPE An elbow forces a change in flow direction. At the elbow outlet, the conveyed media causes turbulence. ESSER TWIN 900 outlet pipes are equipped with highly wear- resistant cast sleeves, just like the elbows, to withstand this heavy wear load.
