STEEL THREADED PIPE FITTINGS MANUFACTURED ACCORDING TO THE BS EN 10241:2000 STANDARD. NORMATIVE REFERENCES: EN 10204, EN ISO 6708, ISO 7-1 PART 1, ISO 7-2, PART 2, AS 1074.

Black & Galvanised Steel Unions - Taper Threads

Black steel unions are used in a wide range of make-and-break joints such as: filters, valves, hoses, machinery and general piping installations requiring periodic disconnections. They are particularly suited to high or low pressure assemblies in air, oil, gas and water. They are available in Steel-Steel, Steel-Bronze and Bronze-Bronze seats with Female-Female and Male-Female end connections.

These unions are electro zinc plated and are available in Steel-Steel, Steel-Bronze and Bronze-Bronze seats with Female-Female and Male-Female end connections. This process gives a complete coating both externally and internally which protects the pipe union at the thread and vital seating areas. They are particularly suitable where there is condensation, such as in air and gas lines. The zinc coating also gives an outside protective coating against rust when exposed to the atmosphere. (The Steel-Steel zinc coated union is an ideal union suitable for most applications where vibration and moisture are present, such as compressed air lines and railway breaking systems)

Ball to Cone Seating in the following combinations:-

STEEL – STEEL (SS)

This is a general purpose combination recommended where vibration is present. The seats are integral and therefore are the most economically priced. This union will suit almost any application. Zinc coating improves the corrosion resistance of the joints to a marked degree where corrosion is present.

STEEL – BRONZE (SB)

A good seat combination where corrosion due to the fluid medium that is being used in the line or where condensation is present and when periodic disconnection is required. Zinc coating improves the corrosion resistance of the joints to a marked degree where corrosion is present.

BRONZE – BRONZE (BB)

This seat combination is recommended when corrosion due to the fluid medium in the pipe line or condensation is a major factor and where constant disconnection is required. This seat combination is ideally suited to steam lines. Zinc coating improves the corrosion resistance of the joints to a marked degree where corrosion is present.
