“ZKZ, LLC” has been operating on the market since 2002. Currently the plant’s primary activities include production of the parts such as “rotation bodies” of carbon, high-alloy and stainless steels used for the manufacture of flanges, pipelines fittings, vessels and devices. The plant provides a complete closed cycle from half-finished product preparing to the manufacturing of finished products (mechanical processing).

“ZKZ, LLC” offers for sale of up to 400 tons of products per month. Orders are taken starting from one piece.

Manufacturing time and terms of delivery to the Purchaser are from one day. In stock of the plant there is a wide range of finished products for immediate delivery.

As a direct manufacturer, our plant offers high quality products at low prices. Deliveries can be made in any quantity and on any terms from EXW to DDP, as our customers may wish.

• Ring blanks; weight - from 20 to 1500 kg, diameter (outer) – up to 2300 mm, height - 500 mm, (following the geometry of the finished product with an allowance of 3-5 mm on the side).

• Grid plates and their blanks.

• Blanks according to customer drawings (following the contour of the required part).

• Blanks for the casing connections, cross connections and preventers (ram, universal, rotating, annular, wellhead, etc.)






• pipelines components with low performance requirements are made of carbon steel ASTM A 105 Gr1, A 106 GrA, B, A 659 CS Type 1020, A 794 CS Type 1020, EN 1.1151, AISI 1020, DIN C22E;

• cold-resistant pipelines components with easy weldability from structural low-alloy steels for cryogenic temperatures and severe winter weather conditions ASTM A 516-65, A 561 Gr70, A 516-55, A516-60;

• heat-resistant pipelines components exposed to high temperatures of the external and internal environments, are made of the steel ASTM SA-387 Gr5, A 193 Grade B5, A 182 Grade F5, DIN 17176;

STEEL GRADES






HEAT TREATMENT

Heat treatment of the blanks involves their heating and cooling at a certain mode. Heat treatment of the

parts contributes to improvement of structure and mechanical properties of alloys, eliminates blanks warping by reducing internal stresses as well as metal machinability by cutting.

Temperature mode depends on the purpose of heat treatment, alloy type, nature and peculiarities of the part operating.

Annealing or normalizing are applied to improve the structure and mechanical properties, which is preparatory but often final heat treatment, finishing the technological cycle of the blanks production.

Normalizing should be applied for low-carbon non-alloyed steel as normalizing improves the structure and mechanical properties (plasticity, impact resistance). Moreover, normalizing process is faster and economically sound (heat-treatment furnace does not work during the period of cooling).

RESEARCH WORKS

Technologies used at the ring blank plant allow to obtain high quality castings equal to forgings in terms of strength properties. Top institutes recommend to use our castings in valve industry instead of forgings and bar iron for manufacture of the choke and hardware flanges.

THANK YOU FOR YOUR ATTENTION!

Thus, use of steel of different grades enables us to produce flanged connections for different operating conditions: flange connection for chemically active media, high pressure pipelines, high and low operating temperatures.

Technologies used at the ring blank plant allow to obtain high quality castings equal to forgings in terms of strength properties, castings have a dense fine grain structure of directional view which ensures obtaining metal with a low content of harmful impurities of sulfur, phosphorus and hydrogen due to melting under protective flux layer without oxides added into the melt.

All blanks are heat-treated, tested for chemical composition and mechanical properties at the plant laboratory certified by the State Committee for the Russian Federation for Standardization and Metrology and fitted with the equipment for non-destructive ultrasonic testing of the blanks quality. Blanks are supplied with the certificate of quality.

With due attention and in the shortest time we will consider your order and provide the minimum prices and production time.
