Abstract

The invention discloses a galvanized and dipped varnish malleable steel pipe fitting. A galvanized and dipped malleable steel pipe fitting, comprising a malleable steel pipe fitting base body, the surface of the malleable steel pipe fitting base body has a galvanized layer and a varnish layer in turn, the galvanized layer is an inner layer, and the varnish layer is an outer layer; the thickness of the galvanized layer is 50‑80μm; the thickness of the impregnated paint layer is 40‑70um, the adhesion is ≤ grade 1, and the impact resistance is ≥70kg.cm. In the present invention, since the galvanized malleable steel pipe fittings are impregnated with epoxy resin, the thickness of the galvanized layer of the present invention reaches 50-80 μm; the thickness of the impregnated paint layer reaches 40-70 μm, the adhesion is ≤ grade 1, and the impact resistance is ≥ 70 kg .cm; galvanized and dipped malleable steel pipe fittings also overcome the problem that galvanized malleable steel pipe fittings cannot withstand acidic and alkaline environment corrosion; also solve the problem of the surface color of traditional malleable steel galvanized pipe fittings and other pipelines and their connectors used in conjunction with it The problem of color mismatch; at the same time, it also improves the antirust effect of galvanized and dipped malleable steel pipe fittings.

Description

Technical field [0001] The invention belongs to a pipeline connector, in particular to a galvanized malleable steel pipe fitting. Background technique [0002] At present, galvanizing technology is mostly used for the surface treatment of malleable steel pipe fittings, but galvanized malleable steel pipe fittings cannot withstand corrosion in acid and alkaline environments. At the same time, most of the surface color of galvanized malleable steel pipe fittings does not match the color of other pipelines and their connecting parts. , Affecting the aesthetics of the construction, it is necessary to separately spray the entire pipeline connected by galvanized malleable steel pipe with protective paint to uniform the color of the pipeline, increase the consumption of protective paint materials, and the anti-rust effect of galvanized malleable steel pipe is not very good. Therefore, how to overcome the defect that galvanized malleable steel pipe fittings cannot withstand the corrosion...
