Whait is process in making LPG cylinder?

Every country has a standard to make this kind of cylinders. For example in my country there is a standard to make this kind of cylinders. And this instructions must to be followed by any factory which want make LPG cylinders. For example this kind of factories , must follows the meassures , welding specifications using special process , the steel used under standard for quality , hardeness , etc. Size of cylinders , shapes , according the use, for example household , automotive , industry ,etc. Any use must have a different design. For example you musn´t use the cylinder desingned for automotive in household and so on. If you want to get more specific information about this , you should go to your local office for standars in your country . So every country has an office for standards which is something like a library where only you can find all standards instructions to make a lot of things.. Eg. Automotive , Mechanical , Chemical , Aircraft ,etc... Regards.


What is s Indian Standard code for painting of LPG Pipeline?

I don't know what you mean by s Indian, I assume you mean South and by Indian I assume you mean the country of India. Most likely there is no governmental specification for buried LNG line. There are 2 main ways to protect buried pipeline. By coatings or wraps Most major pipeline companies specify nominally 25 mils of an Epoxy classified as a FBE (fusion bonded epoxy) that works in conjunction with cathodic protection. Most pipes installed are shop coated with a powder and baked. Rehabilitation uses a liquid applied 2 component epoxy applied with either a plural component sprayer, cardtrigde sprayer for girth welds and small area (a pneumatic powered big caulk gun), or by hand (Poor quality finish - many holidays). The downside of coatings is that they cannot take temps above 450F depending on brand- but that is mostly applicable to crude. They may also fail earlier then wraps - will still have 50yrs+ if applied right. The upside of coatings - they fail safe - cathodic protection will let you know when the coatings have failed. Wraps are another way to go. Polyolefin, bituminous and others, but these are the most popular. Polyolefin upsides - stays pliable for 50yrs+ - newer technology then bituminous. Drawbacks- Does not work in conjunction with CP. No way to tell if they have failed. That is when you get explosions. Bituminous wraps - asphalt based wraps The upside of bituminous wraps. They are low cost for initial investment. The drawbacks of bituminous wraps. They are not fail safe (see above), they can become brittle in far less then 50yrs. Hope this helps
