API RP API Rp 4g Cabria. Installation of underground petroleum storage tank. We recognize our responsibility to work with thc public, the government, and others to develop andto use natural resourcesin an environmentally sound manner while protecting the health and safety of our employees and the public.
To meet these responsibilities,API memberspledgetomanageourbusinessesaccordingtothefollowingprinciplesusing sound scienceto prioritize risks andto implement cost-effective management practices: To recognize and to respond to community concerns about our raw matcrials, products and operations.
To operate our plants and facilities, and to handleraw ourmaterials and productsin a manner that protects the environment, and the safety and hcalth of our employees and the public. To make safety, health and environmental considerations a priority i n our planning, and our development of new products and processes. To advise promptly, appropriate officials, employees, customers and the public of information on significant industry-related safety, health and environmental hazards, and to recommend protective measures.
To counsel customers, transporters and others in the safe use, transportation and disposal of our raw materials, products and waste materials.
To economicallydevelopandproducenaturalresourcesandtoconservethose resources by using energy efficiently. To extend knowledge by conducting or supporting research on the safety, health and environmental effects of our raw materials, products, processes and waste materials.
To commit to reduce ovcrall emissions and waste generation.
To work with rp7f to resolve problems created by handling and disposalof hazardous substances from our operations. To participate with government and others in creating responsible laws, regulations and standards to safeguard the community, workplace and environment. To promote these principles and practices by sharing experiences and offering assis- tancc to others who produce, handlc, use, transport or disposc of similar raw materials, petroleum products and wastes.
With respect to particular c r icumstances,local, state,and federal laws and regulations should be reviewed. API is not undertaking to meet the duties of employers, mantrhcmem, or suppliers to warn and properly train and equip their employees, and others exposed, concerning health state, or fedand safetyrisks and precautions, nor undertaking their obligations under local, eral laws.

Rotary Shouldered Connection Interchange List Common Fixed Cutter Bit Sizes Theratioofthesection modulus of a rotary shouldered box at the point in the box where the pin ends when made up divided by the section modulus of therotary shouldered pin at the last engaged thread.
This recommended practice involves not only the selection of drill string members, but also the consideration of hole angle control, drilling fluids, weight and rotary speed, and other operational procedures.

A drift is a gauge used to check minimum ID of loops, flowlines, nipples, tubing, casing, drill pipe, and drill collars. Thick-walledpipe or tubedesigned to provide stiffness and concentration of weightat thebit. Improper performauce of a device or equipment that prevents completion its of designfunction.
The process of progressive localizedpermanent structural change occurring in a material subjected to conditions that producefluctuating stresses and strains at some point or points and that may culminate in cracks or complete frilcture after a sufiicient numberof fluctuations. A failure whichoriginates as a result of repeated rp7v fluctuating stresses having maximum values less than the tensile strength of the material. Silicak, salt, and phosphate may also be present.

A connection onto the bottom of the kellyto protect the pin end of the kelly used on drill stringelementswhichhascoarse, tapered operations. The last thread on the pin 3. The stress required to producefracbox or the box engaged withthe pin.
An essentially full-opening valve installed immediately below the kelly, with outside diameter parallel and opposite although theirpaths are offset a speciequal to the tool jointoutside diameter. Valvecan be closed to fied minimum amount. The maximum load divided by the zemove the kelly under pressure and can be stripped in the original cross-sectional area of a section separated by shear. The sealing shoulder on a of 48 inches alongthe pipe body from the juncture rpp7g the tool rotary shouldered connection.
The minimum makeup torque is the minimum amount of torque necessary to develop an arbitrarily derived tensile stress in the pin or compressive stress in the box.
This arbitrarily derivedstress level is perceived as being SufEcient in most drilling conditions to prevent downhole make-up and to prevent shoulder separation frombending ep7g. This process makes thejoint m m flexible andreduces the likelihood of fatigue crachg in this highlystressedarea 3.

The amount of variation permitted. A heavy coupling element for drill pipe having coarse,t a p e d threads and sealing shoulders designed to sustain the weight of thedrill stem, withstand thestrain of repeated make-up and break-out, resist fatigue, ro7g additional make-up during spi, and provide a l e a k – p f seal.

A valve immediately above the kelly that can be closed to confinepressures inside the drill string. A pipe end with increased wall thickness. The outside diameter may be increased, r;7g the inside diameter may be reduced, or both. Upsets are usually formed by hot forging the pipe end.
