Looking for a fastener manufacturer that delivers on time?
Production of fasteners ASME / ASTM / ANSI up to 5 tons / day with worldwide delivery
We guarantee terms - We will refund 5% of the order amount in case of violation of the delivery time
ISO 9001:2015 certificate
We will produce according to your requirementsThe ASME B16.5 standard governs the product itself and its practical use. For example, sets the working pressure at a specific temperature for flanges. These standards are based on data published in international standardization.
Sizes and weights for heavy duty steel stud nuts are in accordance with ASME B18.2.2 specification. The ASTM standard affects the electrical, physical, mechanical properties of the product, chemical composition, testing methods and all requirements for rolled metal products (configuration, dimensions, and so on). The most common stud materials (for flanges) are ASTM A193 (Grade B7, B8, B8M, B8T), ASTM A453 (Grade 660), ASTM A320 (Grade L7, L7M) and ASTM A182 (duplex and super duplex bolt). For aggressive solutions and environments, studs can be coated with xylan and other materials.

Project: Omsk NKZ
Task: Flange Fastener Manufacturing
Client: Gazpromneft 
Description: Working with a major oil refinery has made flange fasteners a priority at this stage in our company's life.
In working on a new type of product for us, we got the opportunity to apply the experience of previous cases and our own developments and in a short time become a leading manufacturer of flange fasteners.
This is the result of hard work and proof that the company's development vector, chosen several years ago, turned out to be correct.
Project: ZapSibNefteKhim-2
Task: Supply Foundation Bolts
Client: Technip 
Description: Technip is the largest European company involved in the creation of objects around the world. In 2015-2016, they were looking for contractors for construction in Tobolsk.
The main condition was compliance with high technical requirements for products. Quality control was carried out by a representative of the customer's company, which inevitably led to difficulties due to the insolvency of some contractors.
It was this case that became the starting point in the construction of our own factory. After all, only by fully controlling all stages of production can you be 100% sure of the result.
Project: Amur GPP
Task: Supply of embedded parts
Client: Renaissance Industries 
Description: Work with a Turkish holding engaged in construction and energy began with the supply of foundation bolts to the Amur GPP. By that time, we had our own workshop and were actively developing this area, reducing time and production costs.
Further work on embedded parts for the same site revealed two pain points customers face: timing and traceability. Having experience of working with European companies and focusing primarily on international quality standards, we expanded our production by purchasing equipment for automated submerged arc welding.
Project: Linde Engineering
Task: Supply of foundation bolts - 110 tons
Client: ZapSibNefteKhim-2 
Description: The main principle of our company is honesty in everything, down to the smallest detail.
Integrity is the cornerstone of our brand reputation.
We have gone from completing small orders and tenders in 2013 to joint projects with Linde Engineering, Technip and CASALE.
Looking back, we can say with confidence that the path we have chosen is the right one.
