This guide provides a complete overview of blind flange (flange cover) standards, including ASME B16.5/B16.47 and EN 1092 manufacturing specs, ASTM A105/A182 and EN 10222 material grades, and RF, FF, MFM, TG, RTJ face types. It also covers companion fastener and gasket standards, installation tips, and key applications in petrochemical, power, and marine industries. Essential reading for engineers and procurement specialists.

ASME B16.5 flanges play a vital role in industrial piping systems. Their safety and reliability largely depend on the correct selection and installation of fasteners. The dimensional accuracy, pressure class, and material requirements for ASME B16.5 flange fasteners are strictly regulated. These sta

ASME B16.20 standard for flange gaskets is an authoritative guide published by the American Society of Mechanical Engineers (ASME) that specifies the design, manufacturing, and dimensions of metallic spiral-wound gaskets, jacketed gaskets, and ring joint gaskets for pipe flanges. Selecting gaskets that comply with this standard is a fundamental requirement for ensuring a tight seal at flange connections under high temperature, high pressure, and harsh media conditions.

ASTM A193 B7/B7M bolts, with their excellent strength, toughness, and high temperature resistance, meet the needs of industries such as petrochemicals, power energy, and pressure vessels. The reliability and safety of industrial pipeline and equipment connections are extremely important in high-temp

The JIS B 1180 standard defines the specifications for high-quality Hexagon Head Bolts, covering materials, mechanical properties, dimensions, and surface treatments. This guide explains its types (A/B/C grades, coarse/fine thread), key specifications, advantages like reliability and ISO interchangeability, and critical applications in heavy industry, steel structures, and automotive sectors. Learn procurement tips for correct selection and usage.

This article will delve into the two core standards of ASTM A193 and A320, interpreting the performance characteristics of key material grades such as B7/B7M；B8/B8M;B16;L7/L7M and providing professional guidance for the selection of high-performance ASTM stud bolts.
