Shanxi Solid Industrial Co., Ltd. Welcomes the Year of the Snake with You

Solid will attend Buildexpo Kenya 2026 in Nairobi from July 8-10, 2026. Visit Booth 137, Hall 4 to explore ductile iron pipe fittings, flange adaptors, couplings, dismantling joints and repair clamps for water pipeline projects.

Solid is pleased to announce that we will participate in THAIWATER EXPO 2026, one of the important exhibitions for water supply, wastewater treatment, pipeline engineering, and related infrastructure industries in Southeast Asia.

Learn how to choose between PN10, PN16 and PN25 flange adaptors for water pipelines. Compare pressure ratings, applications, selection factors and common mistakes.

Learn the key differences between restrained and non-restrained flange adaptors, including pipe restraint, pull-out resistance, installation, applications, and selection tips for water pipeline projects.

One of the most common mistakes is selecting a flange adaptor that does not match the pipe outside diameter. Pipeline projects often involve different pipe materials, and the same nominal diameter may have different outside diameters depending on the pipe standard.

Learn what a flange adaptor is, how it works in water pipeline systems, where it is used, and how to choose the right flange adaptor for reliable pipe connections.

A restrained flange adaptor is a specialized pipe fitting designed to connect plain-end pipes to flanged equipment while simultaneously preventing axial pipe movement caused by internal pressure, surge loads, or external forces.

Rubber expansion joints are flexible connectors manufactured from elastomer materials such as EPDM, Neoprene, Nitrile, or Viton. They are commonly reinforced with fabric layers, steel rings, or other strengthening materials to improve pressure resistance and durability.

Flange adaptors are essential pipe fitting components used to create a secure transition between plain-ended pipes and flanged pipe systems.

Corrosion is one of the most common threats to pipeline systems, especially when ductile iron pipe fittings are installed in aggressive environments such as coastal areas, desert regions, wastewater networks, industrial plants, and underground water transmission lines.
