Chapter 6 Description of Supply Limits The principle of the supply boundary is based on the first flange port (or thread or pipe joint) outside the equipment. The description of each part is as follows: The vacuum dehydration element is bounded by the interface flange of the vacuum element and the vacuum pipeline. The steam hood is bounded by its inlet and outlet flanges. The drying cylinder is bounded by the steam inlet and the outlet of the steam head. The spray pipe and air pipe provide the inner part of the paper machine, and leave the interface outside. The above-mentioned parts are the scope of supply of paper machine suppliers, and those outside the boundaries are the responsibility of the paper machine purchaser or other suppliers. Polyester nets, blankets, dry blankets for papermaking, equipment lubricants, installation cables and wires and spare parts are not included in the scope of supply.
