SEAMLESS PIPE
Seamless pipe means pipe without a connection. In practice, seamles pipe is indeed a pipe that is formed without making any connections, so that no part of the pipe has ever been disturbed or changed its material due to welding heat. This pipe is made of solid cylindrical steel, which is perforated in an almost melted state, commonly called a billet. By using this method, pipes of any thickness are possible to produce.
WELDED PIPE
Welded pipes or in Indonesian called welding pipes, are pipes that are processed by the welding method. Welded pipes are usually made of steel plates or strips that are joined by welding techniques. The joints of these welded pipes also vary, some are spiral and some are straight / longitudinal. Steel plates or strips with a certain thickness will be rolled in a circle using a plate bending machine or a roll machine. Welding in welded pipes also varies, some of the most famous welding techniques are to conduct high voltage electric currents on the pipe joints so that the joints will melt and melt into one.
