KVV - Contractor

OT INDUSTRIES-KVV Contractor Co. Ltd. is a leading gas and oil pipeline construction, piping and tank construction company in Central Europe.
Based on our several-decade long expertise in Siófok, we are constantly looking for new opportunities to provide high quality services to our customers through the use of innovative solutions and constant renewal of technology, machine and equipment.
In addition to our activities in Hungary, we have also been present in foreign markets for 40 years now. During this period, we have been actively involved in major projects in Germany, Croatia, Romania, Belarus, Poland, Slovenia, Georgia, Iraq, Kuwait and Kazakhstan. 


Our professional past, references and resources guarantee quality and reliable partnership cooperation to our customers. 

Our major areas of expertise:

Our company is one of the leading companies nation-wise when it comes to vertical-cylindrical, atmospheric, aboveground steel storage tanks.

In addition to construction, reconstruction and repair, we have our own diagnostic team and an independent accredited laboratory, so our company is able to complete non-destructive (and even destructive) tests related to all types of tanks (LT, PT, RT, MT, UH, ET, He2).

From 2013 onwards, our services include cleaning as well. Thanks to a highly innovative, self-developed technology, our staff can clean storage tanksup to 40,000 m3 in a closed system without having to get into them. Due to our unique technology in Hungary, the risks of accidental and environmental damage have been significantly reduced.

Construction, repair, maintenance, renewal and dismantling of storage tanks, complete construction

What we offer our customers:
Repair, manufacture and installation of steel tankbottoms

The main activity of our pipeline construction group is to complete the entire process of implementing pipelines that carry hydrocarbons from the moment of trail-preparation to the last tasks of restoring the surrounding environment.
Thanks to our dedicated and innovative technicians and the state-of-the-art machinery we can build  even 200 kmlarge (1400 mm) diameter pipeline per year.
Along with the pipes, we also carry out the implementation of the additional equipments (block value stations, metering and control stations, pump and compressor stations) and the  necessary equipments required at the crossings of rivers, roads and railways.
In 2015, a new area has been added to our expertise: building geothermal district heat pipelines.
