Pipeline for Sour Servic

Sour service line pipe

  • Product specifications: outer diameter: Φ17.1mm~Φ219.1mm; wall thickness: 2.3mm~40.0mm
    Product Features Short description:
    Line pipe is mainly used to transport oil and natural gas pipelines, mainly used in oil, natural gas, chemical industry, electric power Equipment and other industries.

 Line pipe is mainly used to transport oil and natural gas pipelines, mainly used in oil, natural gas, chemical, power equipment and other industries. 

  With the increasing proportion of sulfur-containing oil and gas wells in the exploitation of domestic and international oilfields, the pipelines in this type of oil wells from the mining to the desulfurization station contain a large amount of sulfides, which puts higher requirements on the service performance of the pipelines. Sour service line pipes are the preferred choice for these environments. Changbao Sour service line pipe product category covers all steel grades of API 5L standard, meets customers’ different use strength requirements, and provides customers with satisfactory pre-sales and after-sales service.

Main grades or grades of service products in Souric environments: BNS/X42NS/X46NS/X52NS   BQS/42QS/46QS/52QS/56QS/X60S/65QS/70QS
  

Product implementation standard  GB/T9711-2011 “Steel pipe for oil and gas industrial pipeline transportation system”;   API SPEC 5L “Pipeline steel pipe specification”

Characteristics of Sour service products:  Changbao Sour service pipeline, using low-sulfur high-purity steel and calcification treatment, the company uses CPE or Assel rolling process to roll seamless steel pipe, the process strictly controls the product size. After heat treatment, the performance of the product fully meets the API 5L standard performance index, and has its own HIC, SSC laboratory. In addition to the standard test, a random sampling test is carried out to ensure the corrosion resistance of the manufactured products.

Product use environment  Sour service line pipe is mainly for Sour oil and gas exploration and development environment, in order to solve the problem of cracking and leakage caused by anti-sulfide stress corrosion cracking and hydrogen-induced cracking ability of ordinary conveying pipe under Souric service environment. Generally applicable to oil and gas transportation environment close to surface temperature, CO 2 partial pressure less than 0.2MPa, and H 2 S partial pressure greater than 0.0003MPa.

 Product specification range: 

  Outer diameter: Φ17.1mm~Φ219.1mm; wall thickness: 2.3mm~40.0mm.
