What does API 6A mean?

What does API 6A mean?

API Spec 6A is an International Standard that specifies requirements and gives recommendations for the performance, dimensional and functional interchangeability, design, materials, testing, inspection, welding, marking, handling, storing, shipment, purchasing, repair and remanufacture of wellhead and christmas tree …

What is the difference between API 6A and API 6D?

API 6D and API 6A are both standards used for Valves in the oil and gas industry. API 6D is standard or specification for valves in any pipeline, including rigs, platforms, skids and production plants. API 6A is standard or specification for valves used in wellhead and Christmas tree equipment.

What are PSL levels?

PSL stands for Product Specification Levels. PSL stands for Product Specification Levels. Pipes are used in different types of environments such as corrosive and non-corrosive. Pipes used in the severe corrosive environments required material that can withstand such process conditions.

What is PR1 and PR2 in API 6A?

PR1 is the basic level of testing and designing in accordance with material/temp/pressure specifications. PR2 is a higher-level validation design procedure which, on occasion, can be requested by customers. This involves carrying out and applying the test procedures specified, such as pressure and temperature cycles.

What is API 6A CRA?

API 6A CRA is a supplement to API 6A, covering a group of high performance alloys – specifically age-hardened nickel alloys, which includes Alloy 718, Alloy 725 and Alloy 925 as well as Alloys 716, 935 and 945. In all cases these alloys develop their high strength through a secondary ageing heat treatment.

What is API 6A flanges?

A standard developed for the American Petroleum Institute, the API 6A specification shares many characteristics with ANSI/ASME flanges. They are dimensionally similar, however their minimal design requirements for operating pressure begin in the 2000# class, which is derived from the ASME/ANSI 600# class.

What is the key purpose of product specification level PSL for subsea equipment?

The PSL system applies a tiered level of material qualification testing and non-destructive testing to equipment as specified by the user/buyer and allows reference to standard procedures to apply continuously higher standards for higher risk equipment applications.

What is a target flange?

Target flange is widely used for pipe line manifold application in oil and gas industry. It is a special configuration of blind flange with lead used downstream and facing upstream to cushion and reduce the erosive effect of high velocity abrasive fluid. Usually a target flange has a counter bore filled with lead.

What is an API ring?

API Ring Type Joints are widely used in high pressure hydrocarbon service in Oil and gas production. Used in both Topside and Subsea applications they incorporate a high integrity metal to metal seal and offer a highly reliable and robust connection.
