About company


In 1964 founded the Institute of VNIIPTchemnefteapparatury, 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. The laboratory has gone from simple devices for expanding to mass production tube expanding machines that meet global standards.

Since 1983, the laboratory has developed the following regulations for the tube expanding: OST 26-17-01-83 Reissue (March 2007), OST 26-17-02-83 Reissue (October 2008.) ОСТ26-02-1015-85 Reissue (July 2007). 00220368-014-2009 STO, STO 00220368-015-2009 STO 0022368-018-2010. In 2013, the laboratory has developed the GOST R 55601-2013.

In 1992 at the research laboratory of tube expanding No. 21 PJSC  VNIIPTchemnefteapparatury  was founded  Techremex Ltd., which has developed and manufactures an advanced series of tube expanding machines, tube expanders and other required for the production and repair of heat exchangers process equipment.

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

2010 Tube expanding machine MER-11M

('M - upgraded')

The company TECHREMEX-LRT Ltd. – 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, and also their repair Department in Russia and CIS have successfully used tools and equipment, TECHREMEX. So, for example, delivered more than 280 of the electrical tube expanding machines in series, the MER and more than 30 electrical tube facing and drilling machines series MET. TECHREMEX is the leader in Russia and CIS countries on this equipment.


Regular customers of equipment and tools, TECHREMEX 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.
