How the 天然气 Distribution Industry Conquers Corrosion

How the 天然气 Distribution Industry Conquers Corrosion

Creating an efficient and long-lasting product is the end goal for manufacturers. While every industry experiences obstacles that may interfere with fulfilling this prophecy, not every industry goes to such great lengths to deter the effects of them. When it comes to corrosion on parts surrounding the gas meter, the natural gas distribution industry is no stranger to investing in corrosion prevention and repairs. After all, too much is at stake when the longevity of a gas part is compromised.

Atmospheric corrosion is the deterioration and destruction of a material and its vital properties. 这是由于 电化学 as well as other reactions caused from the atmosphere surrounding the material. Discoloration, rust, pitting, and cracking are examples of corrosion.

A large portion of a manufacturer’s job is factoring in the possibility of corrosion, especially when metal-based material is involved. If this isn’t taken into account, 生锈可以接管澳门葡京赌场赢钱技巧, significantly lowering its lifespan. In the natural gas distribution industry in particular, this is a major concern as the steel or iron parts are vulnerable to a low-level electrical current that can accelerate corrosion. From there, rust and degradation can wear down the part sooner rather than later. This can mean leaving the part vulnerable to potential leaks, 安全问题, 而且失去了外观吸引力.

In order to address and reduce the effects of corrosion on gas parts, the gas distribution industry is determined to find answers. 事实上, 仅在一年内, a total of $5 million was spent on corrosion prevention and repairs, according to NACE International (National Association of Corrosion Engineers). Such research and tests over time have allowed experts to come to the following conclusion in regards to common corrosion sources and what steps can be taken to reduce them:

让这个话题更进一步, the industry has also been able to utilize certain tests that measure the success of corrosion resistance, 常见的如下:

• 盐雾试验符合ASTM B117
  As the most common ASTM standard test for the job, the Salt Spray Test works by first placing the material in a salt fog chamber. Next, a 5% NaCl solution is atomized at 95°F with a neutral pH of 6.5-7.2. The parts are kept in a continuous fog without touching any other metallic or corrosive material. The materials are checked periodically for rust or decay through the test duration as determined by the manufacturer. A的结果如下.Y. 麦当劳盐雾试验.
  
  
  
  
• Water Immersion Test per ASTM A967
  The Water Immersion Test involves repeatedly submersing a sample in water and drying in order to check for rust and corrosion. Once again, testing duration is determined by the manufacturer.

• High Humidity Test per ASTM A967
  In order to perform the High Humidity Test, the material must be placed in 95-100% humidity at temperatures greater than 100°F for 24 hours to check for rust.

在严重的情况下, when corrosion meets a natural gas distribution part, the lifespan of the product can go downhill. 知道了这一点, ample amount of research and resources have been put toward rectifying the industry-wide issue. A.Y. McDonald does our part by applying coatings to our products that reduce the effects of corrosion, 如前所述. 这包括油漆, 热浸镀锌, zinc plating that’s commonly enhanced with chromate over-coatings and additional sealants, and additional paint over-coatings. 除了, we continue to take corrosion prevention seriously by performing tests such as the Salt Spray Test.
