API is not undertaking to meet the duties of employers, manufacturers, or suppliers to warn and proper
3、ly train and equip their employees, and others exposed, concerning health and safety risks and precautions, nor undertaking their obligations under local, state, or fed- eral laws. Information concerning safety and health risks and proper precautions with respect to par- ticular materials and condit
4、ions should be obtained from the employer, the manufacturer or supplier of that material, or the material safety data sheet. Nothing contained in any API publication is to be construed as granting any right, by implication or otherwise, for the manufacture, sale, or use of any method, apparatus, or
5、prod- uct covered by letters patent. Neither should anything contained in the publication be con- strued as insuring anyone against liability for infringement of letters patent. Generally, API standards are reviewed and revised, reamed, or withdrawn at least every five years. Sometimes a one-time ex
6、tension of up to two years will be added to this review cycle. This publication will no longer be in effect five years after its publication date as an operative API standard or, where an extension has been granted, upon republication. Status of the publication can be ascertained from the API Upstre

30、7 Recommended Practice for Field Testing of Electric Submersible Pump Cable 3 Transportation, Handling and Storage of Equipment 3.1 CABLES 3.1 .I Downhole Pump Cables The recommended method to lift a reel of cable is to insert an adequately sized piece of pipe through the center of the reel to serve
31、 as an axle. The reel should be lifted with a power spooler or with a spreader bar and a wire rope or chain sling attached to this axle. A reel of cable should never be lifted using a sling without a spreader bar as the cable or the cable reel could be damaged. The following are also recommended: a.
32、 Necessary precautions should be taken to protect the cable and reel from damage during storage, transportation or instal- lation of equipment. b. The reel of cable should never be allowed to roll against objects that might crush or otherwise damage the cable or reel. c. A minimum 4-in. clearance sh
33、ould be allowed between the outermost layer of the cable and the flange of the cable reel to protect the cable from damage. (See Figure 2.) d. The reel should be transported and handled with the reel axle horizontal to the ground. e. The reel rims-when transported by conventional means-should be cho
34、cked (blocked) on both sides of the reel, and that the reel should be properly secured by “boom chains” passing through the center section of the reel. f. Chains should never pass over the top of the reel or touch the cable. g. When forklifts are used to handle cable reels: 1. Forks shall be long en
35、ough to support both reel rims; 2. Forks shall be of adequate width to safely lift the reel; 3. Forks shall be locked in position; 4. Lifts shall be made on the reel rims only (when approaching the reel from its end); 5. Only one cable reel shall be lifted at a time. 3.1.2 Motor Lead Extension (Flat
36、) Cables 3.1.2.1 To ensure physical protection, a motor lead exten- sion cable that is shipped separately should be boxed, crated, reeled or secured to a pallet.

41、TIONS, AND GAS SEPARATORS 3.2.1 These components normally are shipped and handled in metal shipping boxes provided by the manufacturer. 3.2.2 These components should be properly supported at points one-fourth the distance from each end inside the ship- ping box and should have proper shipping caps i
42、nstalled in accordance with the manufacturers specifications. 3.2.3 The length of the truck or trailer bed used to trans- port the equipment should adequately support the total length of the equipment shipping box with no more than a 3-ft overhang. 3.2.4 Equipment shipping boxes should be in a horiz
43、ontal position when transported. 3.2.5 Support blocks under shipping boxes should be prop- erly spaced for the equipment load, and boom chains securing the boxes should be located only over these support blocks. 3.2.6 All equipment shipping boxes should be marked by the manufacturer to show which en
44、d should be placed toward the wellhead. When off-loading the equipment at the well location, that end of the box should be placed as close to the wellhead as practical. 3.2.7 and maintained in a horizontal position. 3.2.8 Boxes should not be dragged, bounced or dropped when handled. Shipping boxes s
45、hould be lifted with a two-point lift 3.3 SURFACE AND MISCELLANEOUS EQUIPMENT 3.3.1 Transformers 3.3.1 .I for loading, unloading, and handling. 3.3.1.2 Transformers should be lifted either with cables or a lifting beam. Covers should be bolted in place when cables are used, and a spreader bar should
46、 be used to maintain the transformer in a vertical position. 3.3.1.3 Where a crane or hoist is unavailable, transformers should be skidded or jacked-up for movement on rollers. Care shall be taken to avoid tipping transformers. Jacks should be used only under the jack lugs or bosses provided-never u
47、nder drain valves and the like. Transformers should be provided with lifting eyes 4 API RECOMMENDED PRACTICE 11 S3 3.3.2 Motor Control Panels 3.3.2.1 When transporting motor controllers, they should be secured to the truck bed (or other surface, as applicable) to prevent movement, tipping or excessi
48、ve vibration. 3.3.2.2 Nothing should be placed on top of the motor con- troller. Pry bars should be used rather than hammers for uncrating control panels. 3.3.2.3 The interior of motor control panels (controllers) should be kept clean and dry. All internal components should be examined for shipping
49、damage. 3.3.3 Accessory Equipment 3.3.3.1 All accessory equipment should be boxed or other- wise properly protected and identified when shipped. 3.3.3.2 When transported or handled, this equipment should be provided the same protection and handling care outlined for other system components. 3.4 STORAGE 3.4.1 For extended storage of equipment, the equipment manufacturers should be contacted for specific recommenda- tions. The use of desiccant or corrosion inhibitors, or both, may be desirable. 4 General Surface Installation 4.1 GENERAL All equipment shall be properly installed f
