Summary for chemical cleaning and preservation process Discussion
chemical cleaning and preservation process for carbon steel and titanium pipes is presented as a broad, complex topic rather than a simple recipe. M.K.Murthie asks for exact chemicals, concentrations, temperatures, durations, inhibitors, and a 2- to 3-year preservation method for ASTM A106 Grade B and titanium pipes. The reply cautions that this is essentially two separate processing businesses—steel pipe cleaning and titanium pipe cleaning—and says there are no universal book formulas that fit every case. Instead, the answer recommends retaining a consultant or working with a process vendor who can test sample parts or coupons in a lab and tailor the cleaning parameters to the actual soils and corrosion conditions. It also notes that inhibitor selection depends on the specific operating conditions, and that many manufacturers offer different inhibitors for different needs. The overall advice is to develop the process experimentally rather than rely on a one-size-fits-all procedure.
Q. Sir,
We are looking for procedures for degreasing pickling preservation coating of ASTM 106 grade-B pipes and Titanium. We want full details regarding chemicals to be used at what composition and concentration and at what temperature degreasing and pickling (chemical cleaning) to be carried out effectively. Please give duration to be processed for above cleaning. Please recommend the inhibitor to be used in the chemical cleaning. Please briefly give the detail of preservation of pipes for minimum period of 2 to 3 years.

Hi, Mr. Murthie.
What you are requesting seems to be a very wide ranging, deep, and complete understanding of two entire businesses, i.e., processing of steel pipes and processing of titanium pipes — all before you can begin plant layout efforts. I hope some reader can recommend a few good books on the topic, but retaining a consultant would seem to be a necessary step as there are no book formulas that work for all circumstances.
Concentrations and treatment times would have to be tested with your particular parts, but perhaps you can find a process vendor who can run sample parts or coupons in their lab, and suggest these parameters for you based on the types of soils and corrosion found on your pipes. That way you don’t have to become both a processor and a process developer simultaneously. There are many manufacturers of inhibitors and each has a number of different inhibitors based on your specific operating conditions. Best of luck.
