What is the safety level of stainless steel welded tubes when used in medium and low pressure heat exchangers?
Thread Content
Recently, medium and low-pressure heat exchangers designed with stainless steel welded tubes have been used, with media that are moderately hazardous and flammable/explosive, meeting the regulatory requirements. However, the owner believes that it is less secure than stainless steel seamless pipes, and would like to seek the opinions of experts. If there are no safety issues, how should one persuade the owner? Thank you. What is the safety level of stainless steel welded tubes when used in medium and low pressure heat exchangers? What are their advantages and disadvantages compared to stainless steel seamless tubes? Are there any documents recommending the use of stainless steel welded tubes? What regulations and standards govern the manufacturing and use of stainless steel welded tubes?
You can use the GB/T 12771-2008 standard to convince customers!
2# tbj1860 Thank you for your guidance, tbj1860; happy New Year! Now the owner states that, since the medium is flammable, explosive, and toxic (acetonitrile is classified as moderately hazardous), stainless steel seamless pipes must be used. They simply think that stainless steel seamless pipes are better than welded pipes; how can we convince the owners? Please give me some advice!
