Hi engineers,we are trying to replace several PTFE lined steel pipes for a liquid bromine line. Pressure rating: 0.2 MPa, Temperature: room/ambient. Please see the attached 3 photos: the flanged steel pipes are lined with PTFE. A small hole was drilled on each end of the pipe to supervising...
Sorry that there's a typo. It should be Ti Grade 7 "Ti-0.15Pd". The nominal composition of Grade 16 is "Ti-0.05Pd". They have identical mechanical properties. However, compared to Gr.16, Gr.7 is more often applied in corrosion applications since there are more approved engineering experiences or...
I think I have a technical literature which says Ti-0.5Pd (Grade 7 titanium) is a TYPICAL crevice-corrosion-resistant titanium material for industrial application with Cl ion ≈ 20%, PH2, 120°~130°C. The application is concentrator equipment in salt purification. Due to the large size, just...
Generally, carburization is suitable for low carbon steel(0.1%~0.25%). It is reported that there are new carburization techniques for high-C materials, however, what's the meaning here? I don't get it.

Sorry for the late reply. I just come back from vacation. One of my fellow engineer says it seems that your chemical composition is inapproriate. As a rule of thumb, we should adhere to "Low-Carbon High-Manganese" principle in the production of LCB casting. An actual chemical composition is...
Our engineer once did this heat treatment experiment on LCB casting specimens and I just find some documentation and try to translate the literature partially: three LCB specimens(A, B, C), chemical composition analysed by spectrum apparatus - ok,
Specimen A: Normalized + Tempered. Normalizing...
metengr is right. ASME SA387 Gr.9 plate is not within the jurisdiction of ASME BPVC Section VIII Division 1. It can't be used. I also did a thorough search on Code Cases - 2015 Edition. So far nothing regarding 9Cr-1Mo is found. However, I have a question: when a new edition of code Cases is...
Sulfide stress cracking(SSC) is a special case of hydrogen stress cracking, also known as hydrogen-induced cracking(HIC). This cracking mechanism depends on several factors:hydrogen fugacity, material strength, heat treatment/microstructure, applied stress, and temperature. For many steels...
Dear Hokie66, dhengr & Edstainless, thanks for all your valuable advice. I didn't reply them yesterday because of time difference. For clarification, we are talking about the refurbishment of the 31-meters(102 feet) monument behind the horse statue. You are right, hokie66, the refurbishment work...
Racookpe1978, thanks for your prompt reply and advice. Bronze may be a good idea. However, instead of changing the whole stone monument to bronze statue, the municipal government at present just consider a metal sheet cladding. Could you please recommend a bronze specification for sheets /...
Dear engineers, I am not sure whether this is the right place to pose this question. Recently one of my friends is working on the refurbishment of our city's landmark - Liberation Monument(please see the photo attached). This monument, about 31 meters tall, was made of giant stones about 30...
Thanks for your reply, BigInch. I raise this question is because those F65 flanges supplied were approved by an authoritative Third-Party Inspection corporation appointed by the customer. To my astonishment, they just reviewed the MTR and checked some dimensions. My understanding is A694...
