Stainless steel pipe pickling line

Short Description:

Compared with wire rod pickling and phosphating equipment, most of the medium for steel pipe pickling and phosphating equipment is sulfuric acid, and a small part uses hydrochloric acid. Most users are more suitable for linear type, because the tank body of steel pipe pickling and phosphating equipment is thinner and longer than that of wire rod pickling and phosphating equipment.

The advantages and development trend of automated pickling treatment

Automated pickling surface treatment equipment has advantages that traditional pickling methods and other acid-free treatment methods can’t compare:
★ Good surface quality—— the medium used is still acid, so the surface quality still retains the advantages of traditional pickling
★ Automatic production—— continuous automatic production, high production efficiency, large output, various process parameters are controlled by a computer, production has been automatically. The process is stable, especially suitable for large-volume, centralized production
★ Low production cost—— automatic control of process parameters, the production process can be optimized, with reasonable and effective production media circulation. Ring utilization, while automated production can effectively reduce personnel costs. These factors make the automated pickling equipment. The operating cost of equipment is much lower than that of traditional pickling
★ Low environmental pollution—— the automated pickling equipment can be equipped with advanced waste water and waste gas treatment devices, combined with the characteristics of its own equipment,Achieve relatively low emissions and minimal pollution to the plant and its surroundings. Especially for acid mist treatment and water treatment. On the other hand, if equipped with suitable acid regeneration and wastewater treatment equipment, zero emissions can even be achieved.
With the advancement of technology, automated pickling equipment will gradually realize seamless connection with logistics tracking, MES, ERP and other systems. With industry 4.0, machine vision, cloud big data and other technologies, can achieve a higher degree of intensive, automated, and multi-variety production, bringing huge economic benefits to the enterprise.
