Abstract
A method of assembly of a rotatable flapper valve to an interior of a conduit features the ability to couple the valve plate to its axle outside of the conduit in an independent operation. The conduit is split into first and second sections each having a flared end and a pair of indentations for receipt of the valve axle. While separated, the valve axle is placed in a pair of indentations in one of the conduit sections and then the second conduit section is moved into abutting engagement such that its indentations also partially surround the axle. The first and second conduit sections are then joined by welding.

A method of assembly of a rotatable flapper valve to an interior of a conduit, the method comprising:
- fastening a valve plate to a valve axle;
- selecting first and second conduit sections;
- flaring first ends of the first and second conduit sections;
- subsequently forming first and second indentations in the flared first end of the first conduit section, wherein the first and second indentations in the first conduit section are formed substantially simultaneously with a cylindrical ram;
- forming first and second indentations in the flared first end of the second conduit section such that they will align with the first and second indentations in the flared first end of the first conduit section;
- placing the valve axle in the first and second indentations in the flared first end of the first conduit section;
- placing the flared first end of the second conduit section in contact with the flared first end of the first conduit section such that the first and second indentations in the first flared end of the second conduit section align with the first and second indentations of the flared first end of the first conduit section to partially surround the valve axle;
- and
- fastening the first flared end of the first conduit section to the first flared end of the second conduit section.

- fastening the first flared end of the first conduit section to the first flared end of the second conduit section;
- forming a notch in only the first flared end of the first conduit section;
- and
- welding the first flared end of the first conduit section to the first flared end of the second conduit section at the notch to penetrate the first flared end of the second conduit section.
