Summary #1

The BW/BW (Butt Weld) Conical Junction is a high-performance safety fitting, commonly referred to as a "three-piece fitting", designed exclusively for fully welded piping networks. This specific model makes it possible to create a mechanical breaking point on a fixed line, facilitating the quick assembly and disassembly of a section without having to cut the tubing. Manufactured according to the ISO 4144 standard, this fitting guarantees structural strength and impeccable sealing for the most critical industrial infrastructures.

Summary#2

Made entirely of AISI 316 (1.4401) stainless steel, this fitting has exceptional resistance against oxidation and chemical attacks, particularly in chlorinated or acidic environments. Its high-end composition allows it to withstand severe operating conditions, with an operating temperature range of -20°C to +220°C. It is the reference equipment for the pharmaceutical, food and petrochemical sectors, where the purity of materials and the longevity of installations are non-negotiable requirements.

Summary#3

The major advantage of this union lies in its conical span, which ensures a perfect seal by direct metal-to-metal contact. This technology permanently eliminates the need for polymer seals, which are often prone to wear, drying, or chemical incompatibility. Calibrated for a nominal pressure of PN 20 bar, this fitting offers total safety for discharge or steam circuits. In a specific case, this union is welded between two sections of fixed manifolds, allowing a complete segment to be released for cleaning or inspection by simply loosening the central nut.

Summary#4

This fitting has two Butt Weld (BW) ferrules prepared for a homogeneous end weld with your stainless steel tubes. For example, when creating a permanent heat transfer line, this configuration allows: A total structural fusion with the tube to eliminate any risk of leakage due to vibrations. Maintenance is facilitated by the central movable nut, even on complex and rigid networks. The absence of threads on this model reinforces its mechanical integrity and resistance to repeated pressure cycles, while meeting the highest standards of cleanliness.

Summary#5

Thanks to its three-piece independent architecture, this union significantly reduces technical downtime. For a long-lasting installation, it is imperative to ensure that the two noses are perfectly aligned axially before final clamping. Whether in sugar factories for viscous fluid circuits, in water treatment or in steel mills, this 316 stainless steel fitting is a reliable solution. It allows you to evolve your piping configurations without requiring major structural modifications for each intervention.
