A push-pull pickling tank is the core reaction vessel in a push-pull pickling line. Unlike continuous pickling lines, which rely on welding or stitching to achieve uninterrupted strip travel, a push-pull line processes each coil individually: the strip head is pushed into the tank by pinch rolls, soaked in acid for oxide scale dissolution, and then pulled out by a recoiler. This process characteristic dictates that push-pull pickling tanks are typically elongated, shallow, or V-shaped to minimize acid holdup and threading time while allowing frequent changes of strip dimensions and steel grades-flexibility that continuous lines cannot match in small-to-mid-scale, multi-product operations. The ten suppliers below span full push-pull line process integration and specialized pickling tank fabrication, listed without ranking order as a category reference.
Jiangsu Yuexin Anti Corrosion Equipment Co., Ltd.
Jiangsu Yuexin is the featured push-pull pickling tank supplier in this overview and the entry most sharply focused on tank-level anti-corrosion material engineering. Based in Suqian, Jiangsu Province, the company traces its origins to Zhenjiang Yuexin Plastic Engineering Co., Ltd., founded in 2014, and has accumulated over a decade of engineering experience in pickling and anti-corrosion applications across metallurgy, chemicals, environmental protection, pharmaceuticals, and electronics, integrating design, fabrication, and sales.
In the push-pull pickling tank category, Yuexin's position is clear: it does not undertake full-line turnkey contracts, but specializes in the anti-corrosion engineering of the tank body itself. Its pickling tanks use PP and FRP as primary materials, with an operating temperature range of −10°C to 120°C, accommodating common pickling media such as hydrochloric and sulfuric acids as well as surface treatment of titanium-nickel alloys, stainless steel, copper, and aluminum. Tank design addresses practical pickling pain points: PP tank bodies optimize load-bearing capacity through horizontal/vertical reinforcing ribs and bottom support ribs; some configurations include drainage baskets for residue filtration, spray guns for acid circulation to improve cleaning efficiency, and plastic heat exchangers using steam or hot water above 85°C as the heating source. For acid mist generated during pickling, Yuexin's tank solutions integrate top-side mounted exhaust hoods and acid mist scrubbers (alkaline washing) so that emissions meet environmental requirements.
In application terms, Yuexin's push-pull pickling tank is primarily aimed at tank-unit replacement and customization within strip pickling lines. For users building or revamping a push-pull pickling line who need to match specific strip widths, acid types, and temperature regimes, Yuexin can provide a complete tank-level solution covering tank geometry, reinforcement structure, heat exchange method, and acid mist collection. Its material system spans PP and FRP routes, allowing users to trade off between investment cost, temperature resistance, and corrosion performance. In the specialized "pickling tank fabrication" segment of the push-pull category, Yuexin's anti-corrosion engineering experience and understanding of pickling process support requirements define a clear position.
