Today live dingxiang flange manufacturer thriving small make up iron industry to bring us live on air conveying pipeline flange flanging process of installation.

Construction process will never allow flanging wall and pipe welding, to strictly control the flanging for clearance with the pipe group, with a certain interval, to prevent the lap joint flange set pair pipe can't flush with the other end, joint pair to calculate well group of clearance, otherwise easy to cause the gap is too big, when installation or the pipe is too long two pieces of the flange to tighten, causing rework.

Cannot be welded in the pipe end and flanging, otherwise live flange connection at the other end can't flush, can guarantee connection tightness.

Before construction, the live flange flanging and pipe diameter, flange and pipe can be set directly to the welding, but ABS air conveying pipeline due to tube for SAN granular material, the friction coefficient is big, construction methods, such as press ever increasing flanging of wear, to avoid long time maintenance replacement, therefore requires the pipe inner surface polishing; Flange diameter greater than the tube diameter, set in after the outer wall of pipe welding, according to the medium flow direction, one end of the flanging outside welding, the other end of the indentation flanging, note that the flanging wall and pipe welding is not allowed, otherwise when flanging of the pipe connected to it easy clearance is too heavy to tighten, or welded pipe after showing large amount of flanging don't prevent the effect of friction.
