A weld neck flange, additionally referred to as high hub flange or tapered hub flange, is obtainable in 2 styles specifically regular sort and long sort. The regular sort is beneficial with pipes whereas on the opposite hand, the long sort is beneficial in process plant systems. There’s a circular fitting in an exceedingly weld neck flange that incorporates a projected flange at its boundary. Actually, these weld neck flange undergo typical butt weld process into a pipe and ar machined from a formation. The flange here has range of drill holes which permit the flange get glued to a different flange victimization bolts.
Weld neck flange are brought into use in hostile areas wherever there’s severe pressure, temperature and alternative nerve-racking forces. This sort of flange gets its resilience after you share its stress with the pipe with that it’s welded. They’re additional seemingly to be helpful at pressures up to five,000 psi.
Weld neck flange are brought into use in hostile areas where there is severe pressure, temperature and other stressful forces. This type of flange gets its resilience when you share its stress with the pipe with which it is welded. They are more likely to be useful at pressures up to 5,000 psi.
A weld neck flange, also called as high hub flange or tapered hub flange, is available in two designs namely regular type and long type. The regular type is useful with pipes while on the other hand, the long type is useful in processing plant systems. There is a circular fitting in a weld neck which has a protruding flange at its boundary. Actually, these weld neck flange go through typical butt weld processing into a pipe and are machined from a forging. The flange here has number of drill holes which allow the flange get affixed to another flange using bolts.

Normally, producing of weld neck flange is in varied pressure ratings. As a matter of truth, every category of weld neck projection handles additional pressure than previous category of its construction. Funnily enough, higher the category is, thicker the metal that results in a decent handling of big pressures. The pressure capability of flanges alters once varied factors like the kind of metal used etc. Ironically, because the pressure reduces, the temperature will increase and is so vice-versa.To identify flanges, a troublesome stamp of projection specification is imprint on the outer diameter of the bottom projection. However, the quality and pure mathematics average roughness height (AARH) determines the projection face end. Above all, there are 5 varieties of projection finishes that are as below.
Flanges that are usually bought into use, have a soft seal squeeze in between the more durable projection surfaces that forms a leak-free seal. Materials used for seal will be rubbers, elastomers (springy polymers), soft metal (copper or aluminum) and soft polymers covering a bouncy metal (e.g., PTFE lined unblemished steel).
When the pipe is weld until the flange neck, these pipe flanges get joint. Further, this ends up in transfer of stress till the pipe from flange. Additionally thereto, it conjointly reduces the gathering of stress at the bottom of the hub. Often employed in areas of high, weld neck flanges have a novel inner diameter that is intended to match inner diameter of the pipe. FittingCart manufactures weld neck flanges having a hub of size varying from 1/2″ through 96″ and conjointly in different material grades, sizes and specifications that embody stainless-steel weld neck flanges, carbon weld neck flanges and alloy weld neck flanges. As a matter of truth, weld neck flanges square measure supplied with a raised face wherever the quality height is 1/16: lesser than 400#, flat face and RTJ facing.With the simplest warehouse and storage facilities, FittingCart has numerous weld neck flanges hold on as outputs and prepared to ship anytime. Our company manufactures ANSI B16.5 weld neck flanges, ASME B16.47 Series “A” and B of weld neck flanges severally, pressure Vessel weld neck flanges and conjointly custom weld neck flanges with shoppers demands.
FittingCart’s Weld neck flanges are helpful in applications at severe and significant applications like air mass, warm temperature, volatile and dangerous fluids and temperatures within the sub-zero vary.At FittingCart, we offer customary connections in big selection of pressure rating sizes and categories that area unit per ASME standards of ASME Section VIII Div. one and ASME B16.5. Furthermore we tend to additionally manufacture connections that match up to ASME Section VIII Div. two and additionally alternative specifications once specifications area unit out there. The opposite styles of weld neck projections that FittingCart manufactures are unit Weld Neck Flat Face Flanges and lift Face Weld Neck Flanges.
