API 686: A Guide to Machinery Installation and Installation Design
If you are involved in the installation or design of machinery for petroleum, chemical, and gas industry services facilities, you may want to check out the API 686 recommended practice (RP). This document provides procedures, practices, and checklists for the installation and precommissioning of new, existing, and reapplied machinery. It also helps with the installation design of such machinery to ensure safety, reliability, and efficiency.

In this article, we will give you an overview of what API 686 covers, why it is important, and where you can find it.
What is API 686?
API 686 is a recommended practice published by the American Petroleum Institute (API), a leading trade association for the oil and natural gas industry. API 686 was first issued in February 1996 and has been revised twice since then. The latest edition is the second edition, which was published in December 2009.
API 686 covers the installation and installation design of various types of machinery used in the petroleum, chemical, and gas industry services facilities. These include pumps, compressors, turbines, fans, blowers, gearboxes, couplings, drivers, and auxiliary equipment. API 686 provides guidance on topics such as:
Installation design considerations, such as foundation design, piping design, electrical design, instrumentation design, and environmental design.
Installation procedures, such as receiving and handling, inspection and verification, alignment and leveling, grouting and anchoring, piping and electrical connections, lubrication and flushing, instrumentation and control systems, preservation and protection.
Precommissioning activities, such as cleaning and flushing, hydrostatic testing, mechanical running test, performance test, vibration test.
Installation checklists, such as foundation checklist, mounting plate checklist, grouting checklist, alignment checklist.
API 686 also includes several appendices that provide additional information on topics such as grout materials and properties, alignment methods and tolerances, vibration limits and measurement techniques.
Why is API 686 important?
API 686 is important because it helps to ensure that the machinery installed in the petroleum, chemical, and gas industry services facilities are safe, reliable, and efficient. Proper installation and installation design can prevent or minimize potential problems such as:
Mechanical failures or malfunctions due to improper alignment, leveling, grouting, anchoring, or piping connections.
Electrical failures or malfunctions due to improper wiring, grounding, or insulation.
Instrumentation and control failures or malfunctions due to improper calibration or configuration.
Vibration or noise issues due to improper balancing or isolation.
Corrosion or erosion issues due to improper material selection or protection.
Thermal expansion or contraction issues due to improper piping design or insulation.
Environmental issues due to improper ventilation or drainage.
By following the recommended procedures, practices, and checklists in API 686, you can avoid or reduce the risk of these problems and improve the performance and lifespan of your machinery. You can also save time and money by avoiding rework or repairs due to installation errors or defects.
