API is a leader in the development of petroleum and petrochemical equipment and operating standards covering topics that range from drill bits to environmental protection. These embrace proven, sound engineering and operating practices and safe, interchangeable equipment and materials. Many have been incorporated into state and federal regulations and adopted by ISO for worldwide acceptance.
In order to avoid kinking rotary hose, the length of hose and height of standpipe should be such that while raising or lowering the traveling equipment, the bending radius of the hose will not be less than the value of the Minimum Bending Radius (MBR) provided in Table 7 and C.1 of API Spec 7K at the swivel when the traveling equipment is in its lowest drilling position and at the standpipe when the traveling equipment is in its highest drilling position. The recommended length of rotary hose is derived by the following equation (see Figure A.1).
Please insert the following changes to Std 1104: Section 3.2.2, Change: “ branch weld: The completed weld joining a branch pipe or branch fitting to a run pipe.” to “ branch weld: The completed groove and/or fillet weld joining a set on or set in branch pipe or a set on or set in branch fitting to a run pipe . ”
This Specification under the jurisdiction of the API Executive Committee on Standardization and was developed with oversight from API Subcommittee 11 on Field Operating Equipment. This Specification is intended to give requirements and information to both parties in the design, selection, and manufacture of beam pumping units. Furthermore, this Specification addresses the minimum requirements with which the manufacturer is to comply so as to claim conformity with this Specification.
