304 stainless steel pipe fittings are a general term for various pipe fittings made of 304 stainless steel. 304 stainless steel is a universal stainless steel material, belonging to austenitic stainless steel, with good corrosion resistance, heat resistance, low temperature strength and mechanical properties.

Incoloy 825 flange is a nickel-iron-chromium alloy with additions of molybdenum and copper. This nickel steel alloy’s chemical composition is designed to provide exceptional resistance to many corrosive environments. It has excellent resistance to both reducing and oxidizing acids, to stress-corrosion cracking, and to localized attack such as pitting and crevice corrosion.

ASME B16.11 socket weld pipe fittings are pipe fittings with a socket and a spigot structure, used to connect two pipes. The socket is one end of the pipe fitting, whose inner diameter is slightly larger than the outer diameter of the pipe, and is used to accommodate the inserted pipe; the spigot is the other end of the pipe fitting, whose outer diameter matches the inner diameter of the pipe, and can be inserted into the socket of another pipe or pipe fitting.

ASTM A320 L7 Stud Bolts This is the most common A320 bolt grade. A320 Grade L7 bolts and threaded studs are manufactured from alloy steel with chromium, manganese, and molybdenum. The bolts undergo a heat treating process to reach their required mechanical properties.

ASTM A563M heavy hex nut is a mechanical part with a hexagonal shape and a threaded hole inside. It mainly consists of a nut body and a threaded part. The nut body is a hexagonal block structure with six parallel faces and equal sides. This hexagonal structure makes it easy to use a wrench to operate the nut when tightening and loosening. ASTM A563 Nuts come under the specification for carbon steel and alloy steel nuts that are intended for general, mechanical and structural applications.

Stainless steel socket weld flange have a socket interface. The socket part is a concave structure with an inner diameter slightly larger than the outer diameter of the pipe connected to it. The spigot part is the structure at the end of the pipe, and its outer diameter matches the inner diameter of the socket. This structural design allows the pipe to be inserted into the socket of the flange to form a tight connection.
