ABOUT COMPANY

TEHREMEX since 1966 is the leader in Russia and CIS-countries in electrical tube expanding machines in tube sheets of heat exchangers and machins for facing of tubes.

MER-11M, MER-16M, MET-2 machines are withstand operation in 3 shift mode for minimum 10 years.

Tube expanding machine MER-11М and tube facing and drilling machine MET-2 are a unique development of TEHREMEX, they are have no analogues in the world.

The team of TEHREMEX has developed regulations for the tube expanding: GOST R (STATE ALL-RUSSIAN STANDARD) 55601-2013.

The company TEHREMEX – today

Today in Russia and the CIS, almost all the enterprises of chemical and petrochemical engineering, a refining, petrochemical, nitrogen plants, the chemical and nuclear industries, thermal power plants, enterprises of GAZPROM, ROSNEFT, LUKOIL and also their repair Department in Russia and CIS have successfully used tools and equipment, TEHREMEX. So, for example, delivered more than 280 of the electrical tube expanding machines in series, the MER and more than 30 electrical tube expanding and drilling machines series MET. TEHREMEX is the leader in Russia and CIS countries on this equipment.

Regular customers of equipment and tools, TEHREMEX appreciate its high quality, reliability, dependability, convenience in work; for the quality produced with it works that is the result of our 50 years of experience in research, technical developments and their introduction into production.

The company has a quality management certificate ISO 9001:2015. Also tube expanding machines series of "MER" and tube facing and drilling machines series of "MET" are certified in accordance with the EAC (EurAsian Conformity).

HISTORY OF THE COMPANY

In 1964 founded the Institute of VNIIPTchemnefteapparatury (All-Russian research and design-Technological Institute of chemical and petroleum apparatus), which is the only in Russia specialized scientific research organization in the manufacturing technology of the vessels.

In 1966 the Institute established the research laboratory of tube expanding.

Since 1968, the laboratory, based on its own developments, have organized the production of tube expanders and tube expanding machines.

he laboratory has gone from simple devices for expanding to mass production tube expanding machines that meet global standards.

In 1992 at the research laboratory of tube expanding No. 21 PJSC VNIIPTchemnefteapparatury was founded TEHREMEX Ltd.

In 2006, TEHREMEX Ltd. was reorganized. On its base was established TEHREMEX-LRT Ltd. ("TEHREMEX" - technology, repair, exploitation; "LRT" - laboratory of tube expanding).

PRODUCTS AND SERVICES OF THE LABORATORY OF TUBE EXPANDING

Laboratory of tube expanding development in the field of standardization

Team TEHREMEX together with VNIIPTchemnefteapparatury (All-Russian research and design-Technological Institute of chemical and petroleum apparatus), developed and implemented at the enterprises of chemical and petroleum engineering since 1966 14 names GOST (STATE ALL-RUSSIAN STANDARD), OST (the standard of the organization), STO (the standard of the organization), RTM (Release To Manufacturing) on the basic processes of fastening of tubes in tube sheets, tightening of threaded connections, etc.

The team of TEHREMEX is the co-author of a number of regulations for the fastening of tubes in tube sheets of heat exchangers, tightening of threaded connections in heat etc. all these guidelines ensure the use of unified technological solutions in the production process, contribute to improving its technical level. Most of the documents have been approved by Rostekhnadzor (Federal Service for Environmental, Technological and Nuclear Supervision).
