    [21]: 82 The flare nut, which had previously been installed over the tubing, is then tightened over the fitting to force the tapered surfaces tightly together. Flare connectors are typically brass or plastic, but stainless steel or other materials may be used. Although flare connections are labor-intensive, they are durable and reliable.

    The most common is a tool design with a die and a cone, which is screwed through the handle until the edges are separated at the required angle. [11] [12] [13] A relatively new compact design is the reamer, used as an attachment to a drill. In this case, by friction, the pipe material is heated and gradually flattened to the shape of the nozzle ...

    A blowdown stack can be used to complement a flare stack or as an alternative. The purpose is to prevent 'loss of containment' of volatile liquids and gases. Blowdown from several systems may be combined in a blowdown header prior to the stack. A knock-out pot may be provided at the base of the stack to remove any liquids. Blowdown stacks may ...
