ISO 13680-2020 pdf free.Petroleum and natural gas industries – Corrosion-resistant alloy seamless tubular products for use as casing, tubing, coupling stock and accessory material一Technical  delivery conditions. This document specifies the technical delivery conditions for corrosion-resistant alloy seamless tubular products for casing, tubing, coupling stock and accessory material (including coupling stock and accessory material from bar) for two product specification levels: — PSL-1, which is the basis of this document; — PSL-2, which provides additional requirements for a product that is intended to be both corrosion and cracking resistant for the environments and qualification method specified in Annex G and in the Iso 15156 series. At the option of the manufacturer, PSL-2 products can be provided in lieu of PSL-1. NOTE I The corrosion-resistant alloys included in this document are special alloys in accordance with ISO 4948-1 and ISO 4948-2. NOTE 2 For the purpose of this document, NACE MR0175 is equivalent to the ISO 15156 series. NOTE 3 Accessory products can be manufactured from coupling stock and tubular material, or from solid bar stock or from bored and heat heat-treated bar stock as covered in Annex F. This document contains no provisions relating to the connection of individual lengths of…

ISO 13503-1-2011 pdf download.Petroleum and natural gas industries – Completion fluids and materials – Part 1: Measurement of viscous properties of completion fluids. 3 Measurement and precision Temperatures shall be measured to an accuracy of ±1 °C (±2 °F); pH shall be measured to an accuracy of ±0,1 units. All other quantitative measurements shall be made to an accuracy of ±2 %, unless specified otherwise. 4 Fluid preparation Certain aspects of sample preparation and handling can affect the viscosity or rheological properties of a fluid. During all procedures, steps shall be taken to minimize entraining air into the fluid. The procedure used to prepare the fluid sample shall be documented, including the following information: a) description and/or composition of the base fluid; preparation of the fluid shall be described, starting with the fluid source, such as deionized water, tap water, completion brines, produced water, seawater or type of oil: b) identification of mixing apparatus, container volume, and total volume of fluid prepared; C) identification of each fluid component and amount added; d) the order and method of addition of each component; e) mixing speeds, with time at each speed; f) ageing or holding time prior to measurements, if required; g)…

ISO 13631-2002 pdf free.Petroleum and natural gas industries – Packaged reciprocating gas compressors. ISO 13631 gives requirements and recommendations for the design, materials, fabrication, inspection, testing and preparation for shipment of packaged skid-mounted, reciprocating, separable or integral compressors with lubricated cylinders and their prime movers, for use in the petroleum and natural gas industries for the compression of hydrocarbon gas. It is also applicable to all necessary auxiliary equipment. such as water and gas coolers, silencers, emission control equipment, filters, separators, control panel, piping, etc.. required to install an operable unit in compliance with the purchase specifications and with the intent of minimizing field construction and field-purchased equipment. This International Standard is not applicable to the following: – reciprocating compressors for petroleum and natural gas industries covered by ISO 13707; column-mounted compressors; non-lubricated compressors; compressors having trunk-type (automotive-type) pistons that also serve as crossheads; — utility or instrument air compressors with a discharge gauge pressure of 0,9 MPa (9 bar) or less; compressors driven by diesel engine, gas turbine and steam turbine prime movers. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this International Standard.
