This review from the Lukoil Volgograd Oil Refinery's senior maintenance engineer comments on use of TREM Engineering’s mechanical seals as of 2003. The process pumps at the 13 tags transfer various hydrocarbons starting from LPG to heavy fractions with temperature up to 350C. The pumps are sealed with TREM Engineering SD-series metal bellows seals, shaft size 60, 70, 80, and 90mm:
“All mechanical seals are operating at the moment. The first of the installed seals have been operating for more than three years. No negative feedback. The seals the AVT-6 [CDU] unit were installed to replace seals made by Sealol. These seals, both made by TREM and Sealol, have dry running outboard seals without buffer fluid [as per API 682 Plan 72]. We are planning to use more of these seals in 2004.
This review from the Kirishi Oil Refinery, dated March 2005, signed by Senior Engineer (Mech.), says that TREM Engineering’s mechanical seals, packing, and gaskets have been used since 1999 at the following applications:
The review states that “all products demonstrate high quality conform to industry standards, which helps to maintain industrial, fire and ecological safety.”
This review from the Mozyr Oil Refinery, dated March 2003, signed by Senior Engineer (Mech.), says:
“At the visbreaker and FCC units we have Flowserve pumps, supplied in 2001-2002, which were originally equipped with John Crane and Flowserve mechanical seals. In 2003 and 2004 we installed TREM Engineering’s SD series metal bellows tandem mechanical seals to replace the original seals.
At present the SD series mechanical seals are running, without complaints on our part. The MTBR of SD series mechanical seals is as long as, and in many cases longer than that of the John Crane and Flowserve mechanical seals.”
This review from the Nizhnekamsk Lubricants and Additives Plant, dated September 2002, signed by Technical Director, comments on TREM Engineering’s 70 SD-V mechanical seal operation:
“According to Unit 39/4 equipment upgrade project, shaft seal of pump P-109A was changed from mechanical packing to TREM Engineering’s mechanical seal type 70 SD-V at 01.03.02.
The application date is the following:
The pump was started on 01.03.02. Since then the pump is operating normally:
Pump running time since start up is 3672 hours [at the moment].
During installation of the mechanical seals SKF (Sweden) bearings size 6216 and 7414 were also installed.
We are going to use more 70 SD-V mechanical seals in process pumps of dewaxing, phenol extraction, and others, as per the Safety Improvement Program.”
This review from the Omsk Oil Refinery, dated October 2003, signed by Unit Senior Maintenance Engineer, comments on TREM Engineering’s mechanical seals installed at the AVT-10 crude and vacuum distillation unit.
“At present SD Series [metal bellows] mechanical seals are installed at the AVT-10 crude and vacuum distillation unit at the following positions:
The mechanical seals were installed in November, 2002. At present all mechanical seals are running. Cooled flush is not used. During unit start-up the mechanical seal at P-106 failed (leaked into the barrier fluid tank) as a result of pump running dry for several hours because of difficult unit starting in cold weather. In general, the mechanical seals showed high resistance to abnormal pump operation at start up. We do not have any complaints about work of these mechanical seals. Seals work under API Plan 52 (barrier fluid tank without pressure, with instrumentation and control).”
This review from the Omsk Oil Refinery, dated 2005, signed by Chief Engineer, comments on TREM Engineering’s mechanical packing, gaskets, and mechanical seals installed at the following positions:
“SD series metal bellows tandem mechanical seals are being used in [local manufacturer’s] pumps NK, NKV, and NSD, pumping hot hydrocarbons (heavy fuel oil, bitumen, gas oil) (hot hydrocarbons (heavy fuel oil, residue, gas oil) with temperature up to +380C. The seals are installed without any additional heat exchangers [inside the seal chamber]. Cooled flush lines have been cut off. Up to now there have been no complaints about the products.
MC131 mechanical packing for valves is used throughout the plant in furnace valves, hot pipeline valves, steam valves. Up to now there have been no complaints about the products.
MG140 cut gaskets and sheets and spiral wound gaskets are used throughout the plant on furnace valve flanges, pipeline valve flanges, pump flanges, and heat exchangers. Up to now there have been no complaints about the products.
All installed mechanical packing, gaskets, and mechanical seals are in operation which shows the high quality, fully conform to OST, RD, and PB [Russian safety] standards, contributing to a high level of industrial, fire, and ecological safety.”
This review from the Orenburg Gazprom gas refinery, dated November 2004, signed by Senior Engineer (Mech.), comments on TREM Engineering’s mechanical packing, gaskets, and mechanical seals:
“TREM Engineering’s’ sealing products have been used at Orenburg Gazprom gas refinery since 2002. These products are mainly used for sealing high temperature or chemically aggressive fluids like hot hydrocarbons or fluids containing hydrogen sulfide. The following products have been used since 2002:
MC131 mechanical packing are being used for valves with pressure up to 30 bars and temperature up to 300C; steam condensate pumps with pressure up to 5 bars and temperature up to 120C.
MV410 spiral wound gaskets, with OD up to 2030mm, are being used in pipeline, valve, pump, and heat exchanger flanges with pressure up to 30 bars and temperature up to 300C.
Mechanical seals are being used in [local manufacturer’s] pumps NPS, MT, and NK series, pumping LPG, with temperature 50C and intake pressure up to 25 bars.
During this period we have had no complaints about TREM Engineering’s mechanical seals and sealing materials. The products fully satisfy our specifications. More purchases are planned for 2005.”
This review from the Ryazan Oil Refinery, dated October 2002, signed by Senior Engineer (Mech.), comments on monitored use of TREM Engineering’s mechanical seals, packing, and gaskets:
This review from the Syzran Oil Refinery, dated October, 2003, signed by Senior Engineer (Mech.), comments on 60 SDN mechanical seal operation at Unit 24/8:
“… the mechanical seal was installed in a TKA [local manufacturer’s model] pump at process Position L-24/8s (hydrotreated residue, 360C), Pump House 3, Plant 18, Syzran Oil Refinery, and up to this moment the seal has been operated for 5125 hours during 1 year and 2 months.
During this period of time the pump with this mechanical seal was switched into operation and back to stand-by mode (about 50 times in total).
It was noted that USG series [o-ring] mechanical seals made by Nalchik Works, installed in nearby pumps, had failed several times, each, during the same period of time.
A was also noted that after steam-cleaning of the pump (which is the usual cleaning procedure) it was not necessary to remove and disassemble the seal for servicing.
During all this period of operation the mechanical seal was neither repaired nor serviced.
Considering the above, use of mechanical seals of this type at similar process positions is recommended.”
This review from a Elhovneft plant (Tatneft Company), dated July 2004, signed by Chief Engineer of the plant, comments on TREM Engineering’s mechanical seals, packing, and gaskets working since 2000 at the following positions:
All installed mechanical seals and sealing materials are in operation (except the materials that were changed during planned maintenance), fully conform to OST, RD, and PB [safety] standards, ensuring a high level of industrial, fire, and ecological safety.”
This review from the Ufaneftechim Petrochemical Plant signed by Oil Refinery Senior Maintenance Engineer, comments on use of bellows assemblies made by TREM Engineering. These bellows assemblies were supplied as spare parts kits for imported mechanical seals installed in pumps series KRG1H at the crude and vacuum distillation unit. The process fluids sealed are fuel oil, tar, diesel fuel with temperatures up to 360C.
"Compared to imported products, bellows assemblies made by TREM Engineering are made of same materials, with same specifications, and show same high level of quality."
This review from the Ufaneftechim Petrochemical Plant maintenance contractor signed by general manager, comments on use of TREM Engineering’s mechanical packing, gaskets, and mechanical seals since 1999:
“SD series metal bellows tandem mechanical seals are being used in [local manufacturer’s] pumps ... at the crude and vacuum distillation units, visbreaker, hydrocracking, catalytic cracking, hydrotreating units, and in imported KSB pumps at the visbreaker, which pump hot hydrocarbons (heavy fuel oil, bitumen, reduced crude oil, gas oil) with temperature up to +390C. At this moment we don't have bad comments about the products.
MC131 mechanical packing for valves is used extensively in furnace valves, hot pipeline valves, and steam valves. At this moment we don't have bad comments about the products.
MG140 cut gaskets, sheets and spiral wound gaskets are used extensively on furnace valve flanges, pipeline valve flanges, pump flanges, heat exchangers, economizers at the crude and vacuum distillation units, visbreaker, hydrocracking, catalytic cracking. At this moment we don't have bad comments about the products.
The installed mechanical seals and sealing materials are in operation, demonstrate high quality and fully conform to OST, RD, and PB [Russian safety] standards, adding to a higher level of industrial, fire, and ecological safety.”
