MEKA has devoloped invidual seamless pipeline branching method. Pipeline branching is the more important to obtain high strength. MEKA has used extraction method with cold forming instead of tubing barb. Pipeline branching used extraction method a cold formed main material on the pipe extracted at least four times length of main pipe thickness. This teachings provide %30 strength to connection with butt welding. Filled edge of the branching outlet is provide %10 gain compared with sharp outled to energy conversation.
