A system for further filtering a liquid extract material after an initial extraction process. In an embodiment, the system includes a semi-rigid filter cup that is substantially cylindrical, the filter cup having a top and a bottom, wherein the top is oriented to receive filter media prior to a filtration process, and material to be filtered during the filtration process. The filter cup includes an integrated deformable flange at the top of the filter cup, an integrated top o-ring that is integrated into the top of the integrated deformable flange and an integrated bottom o-ring that is integrated into the bottom of the integrated deformable flange.

After an annular plate is blanked from a metal flat plate in a blanking step, an inner peripheral portion of the annular plate is deformed upward in a burring step. As a result, a hat-shaped intermediate product having an upstanding tubular portion and an annular plate portion is formed. After that, an outer peripheral portion of the annular plate portion is folded step by step toward an inner peripheral side of the annular plate portion. As a result, a folded portion composed of a first folded portion and a second folded portion is formed, whereby a connection portion having a second flange portion is formed.

Pipe flange alignment leveling pins are disclosed to square a flange. The pins include a first and a second cylindrical magnet each configured to have a hollow axis and a positive radial pole and a negative radial pole. A first and a second chamfered hollow pin are engineered to axially receive a respective cylindrical magnet, the chamfer of each pin on an end configured complementary to a flange hole chamfer. A non-magnetic core is engineered to axially slide in and out of the hollow axis of the magnets received into respective pins wherein each of a pair of apparatus resemble a bow tie in cross section configured to align a pair of flanges in two places for a level operation. A level is set across a first and a second assembly of chamfered pins to determine a level flange ready for welding.

An integral nozzle with a section of pipe having a weld end and a flange end. Proximate the flange end there can be a thickened section to strengthen and stabilize the integral nozzle. The wall thickness of the section of pipe can be less than a standard size, such as schedule 40 or schedule 80 pipe, thereby reducing the weight, overall circumference of the weld end, and required material to make the integral nozzle.
