About Us

   "STA" LLC is the successfully working Ukrainian enterprise in Kharkov city established on the basis of modern technologies and equipment. It is one of the main manufacturers and suppliers of parts in the building of pipelines, valves, products of technological and sanitary purposes, of color and black metal in Ukraine.
The company was founded in 2002 in Kharkov city. The main activity of «S.T.A." LLC was the production of seamless steel elbows using induction heating by high frequency, conical reducers, caps and pipe workpiece. In 2012, "S.T.A." company successfully started the production of the ball valves DN 15, 20, 25, 40, 50, air valve (Majewski tap) DN15, check valve, y-strainers, brass unions. Since July 2013 the production of the original bypass valve is started, as well as a big range of threaded brass parts (fittings) is greatly expanded.

Today the range of the company includes:

  • Brass ball valves and air valve (Mayevsky tap);
  • Brass check valves Brass y-strainers Brass fitting connectors universal and turnkey (American);
  • Brass tie-in tank assembly;
  • Brass and steel hose fittings;
  • Brass manifold for underfloor heating;
  • Brass crimp union
  • Steel and galvanized pipeline parts: seamless bent elbows, concentric reducers, elliptical caps;
  • Steel and galvanized pipe workpiece: locknuts, sockets, threads, pipe sleeves, tube with bilateral thread;
  • Bypass valve for heating systems to circulating pumps with check valve or tap.

Among our partners are leading building companies, businesses, food, metallurgical, machine-building, chemical industry of Ukraine, CIS, and countries near and far abroad. Our company continues to grow rapidly; we set new strategic goals and identify promising areas of development. Continuous improvement of production technology, product quality and experience allows the company to offer customers the ability to produce high quality brass items and confirm their compliance with national and international quality standards.

How We Work

Development of 3D models for brass parts
When manufacturing brass parts we widely use 3D simulation, which is used both when we develop the new products and when test products for assembling.
Modern software, professional designers and experience in the production of parts by hot forging can reduce production time and the introduction of new brass products, as well as to guarantee high quality at the design stage.

Production of the press molds for brass forging
Our tool maintenance department is a specialized unit of the company for the production of press molds for volumetric hot brass forging and other items needed in the process.Having at our disposal a unique experience, highly qualified staff and park of mechanical, electrophysical and forging equipment

Volumetric hot brass forging
Our company accepts orders for volumetric hot brass forging for the machine-building enterprises, companies of automotive and electrical industry, oil and gas industry and other organizations including.The production capacity of the company allows producing parts both for the ready standard projects and for new projects according to individual orders.

СNС machining of the brass parts
An important advantage of our production is the process automation of brass workpieces machining on the machines with CNC.
Automatic processing of the parts on CNC machines ensures the stability of the quality and identity of the produced units of the whole lot, as the negative factors that occur during manual operation are excluded.

Parts assembling and quality control
The final step in the manufacturing process of brass products is the assembling of products and output quality control followed by packaging. Particular attention is paid to the correct assembly of the combination of components, compliance with the axial and radial clearances, tightening the thread connections with a certain force and ensuring leak resistance of mating parts with special gaskets and sealants. Product quality control in a separate process that allows to respond quickly the possible deviations in compliance of the ready products quality to the requirements of the standards or technical specifications of the customer, as well as to identify possible defects. 

Examples of brass products

Brass Ball valve

Brass Ball valve is the modern kind of valves for water, which is produced in Ukraine now only by our company since 2012. To organize the production of brass ball valves we organized the production capacity - production facilities ..

Brass caps & lock nuts

Brass caps and lock nuts are threaded fittings and used for connection or locking of pipelines and systems. Due to its high corrosion resistance the brass caps and lock nuts are more preferable to use than similar products made ...

Brass inserts for PPR fittings

We produce brass inserts for PPR fittings with better quality among suppliers offered in the Ukraine. Today the manufacturers of PPR fitting cannot avoid nickel-plating the brass threaded inserts, which are important components in their products...

Brass union

Brass union is the type of pipe connection fittings which allows obtaining quick release connections, where appropriate, for devices that require periodic assembly / disassembly for maintenance (strainers, metering devices, etc.)

Brass plugs & nipples

Brass plugs and nipples are used to connect pipelines or devices with main pipes of the same or different diameters. As the pipes are mainly used of steel, the method of "splicing" and mutual "penetration" of the thread on the border...

Brass manifold for heating systems

The manifold (collector) for heating systems is a device that allows you to distribute and regulate the coolant flow in several heating circuits. It is used when there are at least 2 heating circuits...

Brass filters

"STA" company produces well-known and reliable Y-strainers with stainless steel mesh for water and non- aggressive liquids of solids. Such strainers can be made in several series: "Standard" is ordinary type and "Premium"...

Threaded sockets & reducers

Brass threaded sockets and reducers are very common elements for connecting main pipes with same or different diameters. Despite the great diversity of this type of fitting on the market, the customers often need nonstandard...

Brass crimp couplings

Threadless crimp coupling - an universal tool for connecting non-threaded sections of the pipeline with threaded elements. Crimp repairing couplings can be used to repair water supply systems, heating, pneumatic systems...

Brass check valves

Brass check valves are the simple devices for preventing reverse flow of fluid when the direction of its movement reversed.Check valves of our production have a classic design of the spring valve(body consists of two threaded parts...

Brass tees & elbows

Brass tees and elbows are threaded fittings for branching and changing the direction of the pipeline to 90 degrees. They are made by hot forging which ensures high strength and excellent quality of products both in standard design...

Brass fitting for MP pipes

Brass fittings with crimping collets are used for installation pipelines, made from metal-plastic pipes. The most popular fittings are threaded, which unlike compression fitting does not require special expensive tools for its installation...
