Vessel Head also called tank heads is one kind head used for vessel or pressure vessel.It is a major component of a vessel or pressure vessel. The main role is sealing. Vessel Head mainly used for both ends of vessel or pressure vessel.Vessel Head is to make up and down the bottom of the vessel or pressure vessel.
In April, we got an Vessel Head inquiry from Malaysia as below:
Diameter 3450mm,117.5t+3t(clad),75SF, material SA516 GR70N+SS316L
Diameter 2000mm,68.5t+3t(clad),75SF, material SA516 GR70N+SS316L
The material of Vessel Head is one kind of cladding material,and technical request must accord with NACE MR0175/ISO15156.
NACE MR0175/ISO15156 is standard which The United States Association for Corrosion Engineering and the International Organization for Standardization (ISO) publish standards.
“NACE MR0175/ISO15156 Oil and Gas Industry – Use of Materials in H2S Environments in Oil and Gas Production” is a standard for corrosion corrosion problems developed in H2S-containing oil and gas fields. It is a product of the cooperation of the world’s two major standard systems. The experience and wisdom of the industry symbolize the formation of consensus in this area around the world. It has a good reputation and practicality. The standard consists of three parts.petroleum and natural gas industrial–material for use in H2S-containing environment in oil and gas production.Part 1. General principles for selection of cracking-resistance materials. Part 2. Cracking-resistant carbon and low alloy steels, and the use of cast irons. Part 3.Cracking-resistant CRAs(corrosion-resistant alloys)and other alloys.
The scope of application of the standard: General principles, requirements and recommended methods for the assessment and selection of metallic materials in equipment for the production of oil and natural gas and desulfurization equipment in the hydrogen sulphide environment. The cracking mechanism caused by hydrogen sulfide includes: SSC SCC HIC SOHIC SZC. Appropriate selection of equipment designed and manufactured according to conventional elasticity criteria is not suitable for plastic design (eg based on strain and limit state design). Not suitable for refinery or downstream processing equipment, such as considering the need to see standard NACE MR 0103-2010
We found the material supplier of Vessel Head which can accord with NACE MR0175/ISO15156, and gave customer good Vessel Head quotation.Now the customer have placed Vessel Head order to us.Hope we can have a good cooperation in Vessel Head.
