What are the benefits of installing our stainless steel welded ventilation pipes in the workshop of food processing plants?

Installing stainless steel welded ventilation pipes in the workshop of food processing plants has the core advantages of corrosion resistance, easy cleaning, high safety and long service life, which can effectively meet the strict requirements of food industry for hygiene, environmental protection and production efficiency. The following is an analysis of specific benefits:

First, meet the hygiene standards of the food industry

1. The material is safe and pollution-free.

Stainless steel (such as 304/316L stainless steel) has the characteristics of smooth surface and no pores, and is not easy to absorb pollutants such as grease, dust and microorganisms, so as to avoid the inside of the pipeline from becoming a "hotbed" for bacteria breeding, which conforms to the hygienic requirements of production equipment materials in the National Food Safety Standard General Hygienic Specification for Food Production (GB 14881).

Compared with ordinary carbon steel pipes (which need to be coated with antirust paint, which is easy to fall off and cause particulate pollution) or galvanized steel pipes (the zinc layer may precipitate heavy metals after long-term contact with humid air), stainless steel materials are safer, and the potential pollution risk of pipeline materials to food is eliminated.

2. Easy to clean and disinfect

The surface of stainless steel is corrosion-resistant and acid-and-alkali-resistant, and can be directly washed and disinfected with high-pressure water gun, disinfection water (such as sodium hypochlorite solution) or steam to meet the needs of regular cleaning in food workshops.

The welding process can realize seamless welding of pipeline joints, reduce the problem of crevice fouling in traditional flange connection or threaded connection, avoid cleaning dead corners and reduce the risk of microbial pollution.

Second, adapt to the complex environment of food workshops

1. Excellent corrosion resistance

Corrosive substances such as * * water vapor, acid mist (such as pickling workshop) and grease vapor (such as frying workshop) are often produced during food processing. Ordinary pipelines are easy to be corroded and lead to rust and perforation, while stainless steel pipelines can endure such environments for a long time, reducing the cost of shutdown and maintenance caused by pipeline damage.

For example, in the meat processing workshop (high humidity and salt content) or sauce production workshop (acidic environment), the service life of stainless steel pipeline can reach 3-5 times that of ordinary pipeline.

2. High temperature resistance and fire resistance

Some food processing links (such as baking and cooking) will produce high-temperature gas, and stainless steel pipes can withstand high temperatures of 200-800℃ (depending on the stainless steel model) to prevent ordinary plastic or galvanized pipes from deforming and releasing harmful substances due to high temperatures.

Stainless steel is a non-combustible material, which meets the fire safety requirements of the workshop, and is especially suitable for high-temperature working areas such as frying and baking, so as to reduce the fire risk.

Third, improve the efficiency and stability of ventilation system

1. Reduce airflow resistance and improve ventilation efficiency.

The inner wall of stainless steel pipes is smooth, and the surface roughness is only 0.02-0.05mm (about 0.1-0.2mm for ordinary carbon steel pipes), which can reduce the friction resistance when air flows, reduce the energy consumption of ventilation system (the fan power can be reduced by about 10%-15%), ensure smooth air circulation in the workshop, and quickly discharge odor, hot gas and dust.

2. Strong structure and strong sealing performance.

Adopting argon arc welding technology or automatic welding technology can realize high-strength connection between pipes and fittings (such as elbows and tees), avoid air leakage caused by aging sealing rings in traditional flange connection, and ensure the tightness and stability of ventilation system.

Stainless steel has strong rigidity and vibration resistance, and is suitable to be installed near large food processing equipment (such as centrifuges and shredders), so as to reduce the risk of pipeline looseness or fracture caused by equipment vibration.

Fourth, reduce long-term operation and maintenance costs

1. Long service life and reduced replacement frequency.

Under normal maintenance, the service life of stainless steel pipes can reach 20-30 years, which is much higher than that of ordinary carbon steel pipes (5-10 years) or galvanized steel pipes (8-15 years), especially in highly corrosive environments, reducing the shutdown loss and material cost caused by pipeline replacement.

2. Low maintenance cost

There is no need for regular maintenance work such as anti-corrosion painting and replacement of seals, which can save labor and material costs. For example, traditional carbon steel pipes need to be rusted once or twice a year, while stainless steel pipes only need to be cleaned regularly.

Five, in line with industry norms and sustainable development

1. Meet the requirements of environmental protection and occupational health.

Efficiently discharge the dust (such as flour and starch), oil fume and volatile organic compounds (VOCs) in the workshop, improve the working environment of workers, reduce the risk of occupational diseases (such as inhalation dust hazard), and meet the standards of occupational exposure limits on Hazardous Factors in the Workplace (GBZ 2).

When used with air purification equipment (such as oil fume purifier and activated carbon filter), the stainless steel pipeline can endure the chemical action in the purification process for a long time to ensure the overall efficiency of the system is stable.

2. Recyclable, green and environmentally friendly

Stainless steel is a recyclable material, which can be recycled through professional treatment after being scrapped, reducing the impact of industrial waste on the environment and conforming to the green production trend of food industry.

VI. Typical application scenarios

Function of stainless steel ventilation pipe in food processing

The baking/frying workshop discharges high-temperature hot gas and oil fume to prevent oil condensation from blocking the pipeline and avoid fire risk.

The pickling/fermentation workshop emits acid mist and peculiar smell gas to resist corrosive environment.

The flour/starch processing workshop transports dust to prevent explosion caused by dust accumulation and facilitate cleaning.

The packaging/cooling workshop adjusts the temperature and humidity to keep the air circulating, so as to prevent the food from getting damp and deteriorating.

summary

Stainless steel welded ventilation pipe is the preferred scheme for food processing plants, and its core value lies in balancing health and safety, environmental adaptability and economic benefits. Although the initial investment cost is higher than that of ordinary pipelines, from the perspective of long-term operation and maintenance, production safety and product quality, the comprehensive cost performance ratio is remarkable, especially suitable for high-end food production enterprises with strict hygiene requirements (such as dairy products, baking, quick-frozen food and other industries).
