corrosionguru, Thank you for the information. I believe we have Enecon here locally. As you said application is one factor to consider, I have read studies with results of the coat chipping off concluding that there was a fault in the adhesion. I guess the company will be the one to guarantee...

SJones, Again, thank you for the reference and information. Regards, CR Radovan

EdStainless, I never thought of it that way. Thank you for the additional information. We'll look on to these materials and methods of application. regards, CR Radovan

bimr, We are on it. But process needs the pump to be operating and can only give a short period of time. So for the mean time we are to operate it with a mitigation to minimize the damage. Thank you and regards, CR Radovan

SJones, Yes, I am actually looking into that product by Belzona as it is also one of the product stating it follows ASTM G32-92 testing. But there is the "modified" word in the description for that. However, my question is - are linings be enough to prevent damage to the newly repaired pumps...

EdStainless May I know why elastomer or polymer coating? Most of the articles I have read suggested to upgrade to a harder material or conduct surface hardening. However, what do you mean by "our part cannot support a harder overlay"? I apologize for the questions but i am eager to know why...

Hey guys! We have this problem on our plant. Severe cavitation damage are incurred in our pumps and we are currently studying the cause of it. For the mean time we are in the process of repairing the pump since operation of the pump is critical in the process. We are looking into...

Hey RHurst, Right. We'll check for that tapping point. I never noticed one, though. Nonetheless, we can opt to install one. Winter is not a problem for us. We don't have one. So we'll be looking into the jacketed option. We've contacted some companies that could provide us the solutions for...

Hey George, We will be considering the casing heaters and controls in our design for the resolution for this concern. Thank you very much for your inputs. regards, CR Radovan

Thank you Johnny and RHurst. We will be inquiring our manufacturer if they can provide us with the steam jacketed seal gland. Apperently our mechnical seal is, in fact, a single seal configuration. I am wrong on my previous statement of it being dual. Appologies. With regards to the interlock...

Hey, George. Our pump is steam jacketed; and this includes the stuffing box. I think the use of Plan 53B may cause complication due to the cooling configuration not unless we maintain the barrier fluid at an average temperature higher than the melting temperature. We will as the manufacturer...

Hello, georgeverghese! Thank you for your feedback. The melting point of our sulphur is 116 deg. C. We are not having any problems with the secondary seal of plan 62; however, I will take heed of your suggestion. Furthermore, I am doubting the suitability of plan 01. Is it much better to...

Good day, We currently have two molten sulphur pumps running with API Plan 01/62. However, mechanical seal failure is reccuring. We follow a clearly defined procedure in starting up the pump and kept all temperatures high as required. 1. Any ideas what is causing the seal failure? 2. Is the...

Thank you for the information! I'll try and get the copy of the book. Regards, CR Radovan

Good day! I am currently working in a petroleum refining company. We have a newly built desalination plant for cooling and utility water for the plant. I was wondering if there are some typical preventive maintenance programs that we can follow. I am still studying the equipment and I would...
