Overview

Application

It is mainly used to make high-quality alloy steel boiler pipe , heat exchanged pipe, high pressure steam pipe for petroleum and chemical industry

Main Grade

Grade of high-quality alloy pipe :P1,P2,P5,P9,P11,P22,P91,P92 etc

 

For alloy pipe  A335 , main market is India .  For India Market it oftenly need IBR. today will show IBR for reference.

The Indian Boiler Regulations (INDIA BOILER REGULATIONS, hereinafter referred to as IBR) regulations clearly stipulate that boilers, pressure vessels, pipes, valves, raw materials (plates, bars, castings, forgings) exported to India are required to be inspected by the CBB authorized inspection agency. Authorized inspectors conduct design review and manufacturing process supervisory inspections in accordance with IBR, and conduct on-site installation inspection and registration before entering the Indian market. At the same time, manufacturers need to issue various IBR Forms such as manufacturing, installation and material certification in accordance with IBR requirements. Approval can only be submitted after being signed by the authorized inspection agency.

 

The Indian Boiler Code clearly stipulates that boilers and pressure vessels manufactured in countries other than India need to undergo IBR inspection and certification, and third-party inspection agencies must be authorized by CBB. Therefore, passing IBR certification is a "passport" for the company to enter the Indian market.

 

At present, the projects of domestic engineering companies in India are mainly self-supplied power plants of electrolytic aluminum plants, and investment companies also intervene. Products related to pressure vessels are mainly: thermal power projects, EPC general contracting for engineering companies; direct export of boilers, steam turbines, power station auxiliary, etc.; some pressure vessels used in petrochemical industries; valves, pipe fittings and other components; steel pipes, steel plates and other raw materials.

 

With the help of rich industry certification experience, Yunquan Testing can provide IBR related inspection services, standard training, personnel training, technical consultation and evaluation, IBR related welder certification and process qualification accreditation services, and issue related compliance with the CBB authorized inspection agency. Certificates, for example, FORM certificate, IBR welder certificate, etc.
