Underground Line Testing Piping, Tubing and Fittings

If you have an ammonia system it’s extremely important that you follow all regulations for your system. You want your operation to run as smoothly and as safely as possible. This means that recommendations are given for a reason and should be followed to the letter to avoid any safety slip ups. Ammonia Propane Solutions can help you adhere to all regulations and assure that your system is working safely. 

What are the regulations for underground line testing piping, tubing, and fittings? 

According to CGA G2.1 – 2014 5.6 – All piping, tubing and fittings must be made of steel or other materials suitable for anhydrous ammonia service. Brass, copper or galvanized steel pipe or tubing must not be used. All piping must be supported in accordance with good piping practices, and provisions must be made as necessary for expansion, contraction, impact, vibration and settling.

Why is this the case? 

It’s important to take into account that chemicals are dangerous and can be harmful to your health. Additionally, they can be corrosive to certain metals or certain metals are not able to contain them. This is why it’s so important to follow regulations that tubing and fittings must be made of steel or other materials suitable for anhydrous ammonia specifically. 

Non-Refrigerated System Regulations

Piping used on non-refrigerated systems must be at least ASTM A53 Grade B seamless or electric resistance welded pipe. Pipe joints must be threaded, welded or flanged. Pipe must be at least Schedule 40 when joints are welded or welded and flanged. Pipe must be at least Schedule 80 when joints are threaded. Threaded nipples must be seamless. Cast iron fittings must not be used.

After assembly, all piping, fittings and tubing must be tested and proved to be free from leaks at a pressure specified by ASME B31.3 or ASME B31.5 as appropriate. Underground piping must be evaluated at a minimum of every 5 years to ensure leak tightness.
