With the exploration and innovation of company people, gradually formed four major advantageous products: steel plate, steel pipe, stainless steel, special steel.
The pickling treatment results in a chrome-rich surface. Although the stainless steel will spontaneously passivate after pickling (forming a protective chromium oxide film) by exposure to sufficient oxygen in the outside air, closed systems are generally chemically passivated.
New Steel Pickling Process Applied Without Nitric Acid The usual challenge for stainless steel pickling involves removing all scale, iron contamination, and welding oxides to achieve a fully passivated surface with an even, clean, and aesthetic finish.
stainless steel surfaces for their intended service conditions. If stainless parts are contaminated with grease or oil, then a cleaning operation prior to acid treatment should be carried out. PICKLING AND PASSIVATING STAINLESS STEEL Light scaling left on weld caps and heat tint on the surrounding parent tube surfaces can usually be removed by acid pickling.
Both pickling and passivation are chemical treatments applied to the surface of stainless steel to remove contaminants and assist the formation of a continuous chromium-oxide, passive film. Surfaces must be free of grease and dirt before using these acid treatments. Stainless steels resist corrosion best if they are clean and smooth.
Risks during pickling and passivating. The quality of the end product stands or falls with the quality of monitoring the pickling liquid. Pickling baths can be contaminated by metals, be (almost) saturated or have the wrong composition, causing irreparable damage to the precious metal parts and products.

Main Purpose: Widely applied for chemcial industry, pressure vessel, engineering components, small fittings of stainless steel, nonstandard parts, stainless steel pipe,such as foods, printing, dyeing, aviation, oxidation removal.It has obvious features:improving appearancepickling surface stainless steel pipe applied to industry
Chemical pickling has an inherent advantage in that it will preferentially dissolve these regions leaving only the sound metal behind . Abrasive methods such as grinding or brushing perform this task less successfully; brushing, particularly, might act only to polish and/or embed oxide particles within the steel surface  , whilst grinding pickling surface stainless steel pipe applied to industry
Chemical Surface Treatment of Stainless Steel Types of Process, how they work and their Limitations Left: Using pickling paste on a weld on the inside of a 4436 steel pipe. Right: Steel-Tech Pickle Gel 122, a nitric acid + hydro uoric acid based paste, useful for normal stainless steel. Applied by using a special, acid resistant brush.
Passivation uses either nitric acid or citric acid that are not recognized as being as aggressive as the acids used in pickling. Passivation does not typically go below the surface of the metal and does not change the properties of the metal. The oxide layer left by passivation is only .0000001 inch thick.
Pickling is a metal surface treatment used to remove impurities, such as stains, inorganic contaminants, rust or scale from ferrous metals, copper, precious metals and aluminum alloys. A solution called pickle liquor, which usually contains acid, is used to remove the surface impurities. It is commonly used to descale or clean steel in various steelmaking processes.
Pickling and Passivation. Both pickling and passivation are chemical treatments applied to the surface of stainless steel to remove contaminants and assist the formation of a continuous chromium-oxide, passive film. Pickling and passivation are both acid treatments and neither will remove grease or oil.
Pickling steel is the process of applying an acid solution to remove heat affected zones along with the underlying chromium reduced layer from the stainless steel. Pickled steel is free from surface carbon steel contamination and embedded iron particles. It typically leaves a dull, matte gray finish.
Pickling & passivation are chemical treatment applied to stainless steel pipes, tanks, vessels, machinery, equipments and their parts. Pooja Pickling and Passivation No.1 pickling and passivation services provider in india.
Disclaimer: Pickling products rely on acid to restore the passive layer of your steel. This comes with risks of both personal injury and damage to the steel if improperly applied or used. The information in this guide is intended to serve as a general overview of the benefits and concerns regarding stainless steel pickling.
Stainless Steel Pickling Gel is Stainless Steel Weld Cleaning Pickling Gel Paste used to clean Stainless Steel weld seams and surrounding areas. It is applied with brush, without prior doing any wire brushing or grinding or buffing.

Pickling is the pre-passivation process of treating stainless steel parts with a hydrofluoric acid solution, which would remove oxide scale and heat tint while dissolving steel flecks embedded in the part. Because of EPA regulations, however, this aggressive pre-treatment is increasingly rare, and few companies still practice pickling.
This technical review article describes the properties and characteristics of stainless steel in sanitary design when used as a food contact surface, particularly when compliance with the requirements of standards promulgated by 3-A Sanitary Standards, Inc. is intended.
like after a glass blasting. This is because of the increased surface roughness due to the etching of the steel. Applying the pickle can be done in two ways. The easiest one is to simply immerse the specimen into the pickling bath. However, is this not possible, the pickle can be applied as a paste.
Manufacturer of Stainless Steel Pickling Dip liquid STAR Dip - Stainless Steel Pickling Dip Liquid Star Dip, Spatter Remover 511 offered by Krystal Surface Solution, Mumbai, Maharashtra.
The purpose of pickling carbon steel pipe is to chemically remove the oxides, rust and oil from the inner surface of the pipe and vessel to obtain the glossy metal surface, to ensure the cleanliness of the inner wall of the pipe, and to prevent rust after pickling But also makes the bottom of the pipe wall metal to be protected to prevent pickling surface stainless steel pipe applied to industry
VK Jelly Stainless Steel Pickling Gel Pickling Paste is used for cleaning weld seams and nearby heat affected surface areas. It is used to remove heavy scales, discolouration, annealing colours, rust particles near weld and welding affected area by heat.
Pickling Agent for Stainless Steel. Products. pickling surface stainless steel pipe applied to industry applied for stainless-steel polishing on luster with high speed and efficiency; provided with current commutating pickling surface stainless steel pipe applied to industry
protective oxide film on stainless steel and thus lay the underlying metal open to corrosive attack. Because of the inherent characteristics of oxidizing and reducing acids, mixtures of the two acid types are used for pickling stainless steelsthe most frequently used solution being a combination of nitric and hydrofluoric acids.
Stainless Steel Finishes. The finishing industry uses numbers and letters to define 13 stainless steel surface finishes. The first five, numbered 0 to 2, are mill finishes; 2B is among the most common for fabricators to start with. The other eight finishes, numbered 3 to 10, are applied by steel producers, toll processors, or fabricators.
AVESTA FINISHING CHEMICALS / PICKLING HANDBOOK 5 Stainless steels and the need for cleaning A good stainless steel surface is clean, smooth and fault-less. The importance of this is obvious when stainless steel is used in, for example, faades or applications with stringent hygiene requirements. However, a fine surface
Stainless steel pipe surface treatment process flow is relatively simple. But in actual processing, the difficulty of pickling passivation process is relatively large, generally divided into two aspects: on the one hand, stainless steel pipe can not be removed by ordinary derusting method to remove stainless steel pipe surface oxide skin.
product characteristics, and costs of production for steel pickling operations.
