What manufacturing problems can occur during the production of a GOST Flange?

These Russian standard flanges are robust and sturdy, withstanding high pressure and temperature. As a trusted GOST 33259 flange supplier in UAE, we acquire and stock only premium-grade products suitable for offshore oil refineries, natural gas processing, railroads, and process instrumentation. Using poor raw materials and outdated production techniques is the root of manufacturing problems in this category.

Buyers can encounter cracks, improper sealing (leakage), non-compliance, and dimensional errors when procuring a GOST 12821 flanges from manufacturers with inadequate quality control.

How do I check the mill test certificate of a GOST 33259 flange?

Suppliers of a GOST 33259 flange include the chemical and mechanical properties in the Mill Test Certificate, also called MTC. It lets you trace each production step and verify the quality of the raw materials.

While reading the MTC of GOST 12821 slip on flanges, clients should cross-check the product specifications, like dimensions, quantity, required properties, and compliance with GOST.

What is the pressure class at which a Russian standard flanges can be used?

We can deliver these flanges from DIN15 to DIN1600 for pressure ratings of 600 to 2500 KPA. A Russian standard flanges can comfortably operate at PN6 through PN160. It gets designed to tolerate critical conditions in oil fields, trains, factories, etc.

The pressure rating will also depend on the material and the design. For example, GOST 33259 threaded flanges may not perform as well as weld-neck alternatives.

What is the hardness of a GOST 12821 flanges?

This flanges typically uses stainless steel material and showcases excellent strength. The hardness of a GOST 12821 flanges will depend on the exact material grade. For instance, it stands at 95 on Rockwell B for stainless steel 316.

Can GOST 12821 blind flanges be used in high-temperature applications?

High pressures and temperatures are not a concern for GOST 12821 blind flanges. Based on the stainless steel grade employed for production, they tolerate a minimum of 425°C at prolonged exposure.

What is the impact of coating on the price of a GOST standard flanges?

These products stand out for their tolerance against oxidation and corrosion. These desirable traits of a GOST standard flanges get enhanced by anti-rusting paint, black paint, or zinc plating.

Additional processing increases the final costs of a GOST 12821 PN6 welding neck flanges.
