MATTECH, s.r.o. (Ltd. company) was established by its present owner from the very beginning in 1992. Since then, the company has been successfully extending its production programme, whose core lies in the proposal, calculation, production and services of flow meters with throttling devices which are in compliance with ISO 5167-1 up to 5 international standards. In the course of two decades, the company’s production programme has been extended to production of separation, mud-discharge and condensation vessels, flow straighteners, restriction orifice plates, multivariable restriction orifice plates, special orifice plates and plate discs, welded-on pieces, fittings, chambers for level measurement, steam coolers, and other components for mechanical parts of metering circuits. We have developed meter tubes with flow meters, such as eccentric orifice plates, critical nozzles and multi-nozzles. We have also developed meter tubes with integrated orifice plate for measurement of flow in small diameter pipes. We have been working on development as well as wider use of segmental and multi-bore orifice plates across all industries. We have been developing our own technological processes for proposal, calculation and production of special orifice plates and special nozzles both for industrial use and testing.
Quality Management System
In 2001 MATTECH, s.r.o. implemented the quality management system and was successfully certified by the British company Lloyd´s Register Quality Assurance. In the course of 2002–2003 the company was fully certified for manufacturing the pressure components according to Directive PED 97/23 EC.
In 2012–2014 the company was successfully certified on welding and manufacturing of pressure components for nuclear power stations. Quality management systems as well as pressure components quality management is verified every year by the internal and customer audits and it is also regularly certified by auditing company. In the course of 2016 the quality management system is being re-certified in compliance with ISO 9001-2015 standard and amended Directive for manufacturing pressure components PED 2014/68/EU.
Together with the development of manufacturing programme we made efforts to ensure quality of our products, not only from technical point of view, but legislation as well. Our company obtained new permissions to its specialized activities valid within European Union and Russian Federation.
The interest of MATTECH s.r.o. is focused on human and professional development of our employees aimed at high degree of independence, professionalism and customer mindedness. The company employs highly qualified engineers, M and R technicians and experienced workshop operators. Our employees are trained in new technologies and manufacturing processes every year, we put emphasis on developing human and professional skills, including financial supporting their leisure activities. Employees in production are trained in new technologies of machining and operation of CNC machines including regular trainings in work safety and fire protection. Company’s management is aware that qualified and hardworking people with good morals is the key of the company’s prosperity. For these reasons, much efforts, time and funds are paid to human resources.
In spring 2003 MATTECH s.r.o., moved to its own premises with an area of 4, 000 m2, in which there are several manufacturing and administrative buildings with high quality technical background. These manufacturing facilities were extensively rebuilt in 2011–2013 and a new production hall was built, too. Nowadays, other manufacturing and preparation facilities are being built, including new parking lot on company’s premises.
Principle of Measurement
Orifice plates, nozzles and Venturi tubes represent unambiguously defined (by the standard) and perfect design of mechanical flow meter without moving parts, that can be used for the measurement of any fluids or gases when maintaining conditions of a single-phase and homogenous flow. MATTECH s.r.o. is due to its specialization a unique manufacturing company, that revived measurement by mechanical flow meters after 1992 and during its 24 years of existence it has produced more than 12, 000 pieces of orifice plates, nozzles and Venturi tubes both for home market and for export to every corner of the world – from North to South – from extraction of natural gas beyond the Arctic Circle up to the measurement of steam flow in a solar power plant in the desert. From East to West, from orifice plates supplies to oil fields in the Gulf of Mexico to supplies of nozzles for power plant units in Asia. Compared to electronic flow meters of the competitors throttling devices by MATTECH are the most reliable types of flow meters with long service life due to designs proved in decades. Their service life is often beyond the lifetime of connection pipes. Uncertainty of the orifice plates is often fully comparable to any electronic competition, and if these are calibrated by wet method at the test room (by fluid or gas), even though it is beyond the standard requirement, then the orifice plate, nozzle and Venturi tube, that are precisely manufactured, achieve higher accuracies than it is stated in the standard. Favorable purchase and operating costs of measurements with orifice plates, that is maintenance-free and without need of spare parts, are other benefits for our clients.
Development, design and construction
The important part of MATTECH s.r.o. is its own development focused on new products and new innovative manufacturing technologies aiming at increasing competitiveness of the meters at home and international markets. Design and construction are made in brand new 3D construction CAD programs from Autodesk company. Experienced staff and junior engineers working on design and construction prepare data for production and they take part in maintaining high quality of products. Calculations and designs of measuring circuits are used as technical support for design, supplier and assembly organizations. Flow meters are manufactured and supplied in compliance with ČSN, ISO, ANSI, ASME, GOST standards, or according to specifications and requirements of the customer.
Parallel with the construction of new facilities and expansion of the production programme of MATTECH s.r.o. new CNC machines and technical equipment is being purchased. Nowadays, advanced hall for manufacturing is being built, which is equipped with high-lift and lifting technology with capacity up to 5 tons. In its manufacturing area there are installed all up-to date CNC machine tools essential for production of all flow meter components with machining range from micro dimensions to dimensions exceeding one meter up to workpieces of many tons. Manufacturing facility consists of storage, handling and assembly facilities. The manufacturing facility is followed by company’s own certified welding with staff certified for welding pressure components and parts for nuclear power stations. The whole manufacturing process is completed in our coating plant and pressure testing laboratory for test pressures up to 80 bars. Concept of the production is focused on minimization of sub-supplies and cooperation aimed at ensuring high quality of our products.
In 2015 MATTECH s.r.o. purchased and developed unique calculating computer program MATTECH® DELTA Software® for easy and quick designing and calculation of primary devices for the measurement of gas, vapours, water and fluid flow. This software provides the technicians and other users with high flexibility as well as with uncommon possibilities compared to other calculation programs. It has been developed for 20 years and its functionality was verified in many engineering and construction companies. In 2016 the software was approved by the Czech Metrology Institute. See more information about the software in the separate chapter.
