Api specification 6a

Type 6B may also be used as threaded flanges. Actuators for adjustable chokes are covered under If a running tool is preheat-machined to different diameters, the prolongation shall be taken from the end having the largest diameter. Reduce the pressure to zero between all holding periods.

API - 6A - 20th Edition

The manufacturer's written specified requirement for non-metallic materials shall define the following: Test pressure- measuring devices shall comply with the requirements of 7. Acceptance criteria for forgings shall be in accordance with manufacturer's written specifications. Yes No Lock screw function: Search the history of over billion web pages on the Internet. Additionally, special corrosion- and abrasion-resistant materials, coatings or overlays shall be used for adjustable choke stem tips and positive choke flow beans.

For batch heat-treatment only: Impact properties as determined from these tests shall satisfy the applicable requirements of Table 6.

Casing-head spools are attached to the top connector of housings or other spools. A complete reorganization of the speciifcation requirements are now grouped by specific activity and not by PSL, making it easier to determine the specific requirements for all PSLs in one location and not spread throughout the document. The monitored holding period shall be at the rated working pressure.

See also Annex M for listings of tables and figures. The equivalent round ER section of all heat sinks shall be determined in accordance with the methods of 5. Impact test temperature shall be no higher than the lowest anticipated service temperature. However, it is the responsibility of the manufacturer to specify other pressure-boundary penetrations which have been qualified to meet performance requirements.

If the overlay material is not considered as part of the specifiation or this International Standard's design criteria, a tensile test and an impact test of the overlay material are not required. These tolerances only apply to the materials covered by Table 8.

Check valves shall be tested from the upstream side.

Valves speciifcation meet all the requirements of Clause 4. Sample connections shall be provided in the tank and in the return line to the tank so that representative samples for sand content and viscosity analyses can be taken. The subscription updates itself, so your subscription automatically reflects the latest edition.

Users of this annex should review all notes and explanations that accompany the same table specified in the main body of this International Standard. Maximum flowing fluid temperature at wellhead: Acceptance criteria shall be appi accordance with the manufacturer's specifications.

speclfication Analysis of produced fluids may not predict the field performance of metallic or non-metallic material. Acceptance criteria for critical dimensions shall be as required by the manufacturer's written specification. Questions concerning the interpretation of the content of this standard or comments and questions concerning the procedures under which spfcification standard was developed should be directed in writing to the Director of the Standards department, American Petroleum Institute, L Street, N.

High-pressure connections as described in 4.

API Spec 6A

The chemical specifiication of the deposited weld metal at that location shall be as specified by the manufacturer. The manufacturer shall have a written procedure for storage and control of welding consumables.

In no case shall an individual impact value fall below two-thirds of that required as a minimum average. API standards are published to facilitate the broad availability of proven, sound engineering and operating practices. The pressure applied shall be equal to the rated working pressure of the actuator.

The manufacturer shall specify and verify critical dimensions.

Leakage by the thread during the hydrostatic testing of a threaded wellhead member when joined with a threaded test fixture is permissible above the working pressure of the thread. No Yes If yes, type: If the manufacturer's pressure rating specfication the maximum rated load is not equal to the maximum rated working pressure, repeat the test using the rated maximum working pressure of the hanger with the ali rated hanging load at that pressure.

    I think, that you are not right. I am assured. I can defend the position. Write to me in PM, we will discuss.
