JIS G3452 pipe manufacturing method

According to JIS G3452, the process of manufacturing carbon steel pipes is as follows:

The pipes are mainly manufactured by resistance welding or butt welding. After manufacturing, the pipes are usually delivered in the manufactured state.
The cold-worked pipes need to be annealed after manufacturing. The purpose of this is to release the stress generated during the manufacturing process and improve the ductility and toughness of the pipes.
The ends of the pipes can be threaded or plain. For pipes with a nominal diameter of 350A and above, plain ends are usually used. For pipes with a nominal diameter of 300A and below, threaded or plain ends can be selected. Beveled ends can also be selected if the buyer has special requirements.
If a threaded end is selected, a tapered thread needs to be manufactured in accordance with JIS B 0203. One end of the thread needs to be screwed into a sleeve that complies with JIS B 2301 or JIS B 2302. For the end that is not screwed into the sleeve, a thread protection ring or other appropriate protection method is required.
Before threading the pipes and sockets, galvanizing is required. Galvanizing protects the metal from corrosion and prolongs its service life. The zinc used for galvanizing should be grade 1 distilled zinc ingot specified in JIS H 2107 or at least equivalent. Other general matters of galvanizing should be carried out in accordance with JIS H 8641.
Before galvanizing, the pipes and sockets need to be sandblasted, pickled, etc. This can ensure the adhesion of the galvanized layer and make the pipes more corrosion-resistant.
