Flanges

Fed up of ill-fitting and poor quality flanges?

After welding, flanges are the most commonly used method for attaching pipes, valves and pumps. If the quality of the flanges you use at your plant isn’t the best, you will only end up with broken and leaky pipes and fixtures. You certainly don’t want that happening, do you?

When buying flanges, your ultimate focus should be on quality, durability and availability of options that are right for you. At Forxar, you get all of this, along with world class customer service.

Why use ASME B16.5 Flanges?

  • Heat code traceability
  • 100% material annealed and passivated
  • High quality steel finish
  • Three chambers cleaning system

How does it work?

Flanges are used for connecting pipes, valves, pumps or other equipments. Usually, the flange is attached to the equipment using screws or welding. In case you need to attach multiple flanges together, they are attached using gaskets to make sure they fit properly and there is no leakage or gaps.

Where is it used?

Most commonly, flanges are used to fix equipments in the petrochemical industry. But being so versatile, it is now used almost everywhere. The oil and gas industry is another major industry that used flanges for fixing equipments.

Why buy from Forxar Industries?

Flanges might not be as significant as a valve, pipe or the actual equipment. But if the quality and functionality of the flanges isn’t perfect, it could result in serious loss and damage.

At Forxar industries, our products, flanges included, are approved for sale only after a through quality check. Unless our specialists have checked and double-checked the product, we don’t send it out to the customer.

When you buy flanges from Forxar, you never have to worry about leakage, breakage, damage or any quality issues.

We are 100% committed to quality and customer satisfaction.

NOTES: (For 150# & 300# Class)

(1) This dimension is for large end of hub, which may be straight or tapered. Taper shall not exceed 7 deg on threaded, slip-on, socket-welding, and lapped flanges. This dimension is defined as the diameter at the intersection between the hub taper and back face of the flange.

(2) The minimum thickness of these loose flanges, in sizes NPS 3 ½ and smaller, is slightly greater than the thickness of flanges on fittings, which are reinforced by being cast integral with the body of the fitting.

(3) For Class 300 these flanges may be supplied with a flat face. The flat face may be either the full tf dimension of thickness plus 2 mm or the tf dimension thickness without the raised face height.

(4) Dimensions in Column 15 correspond to the inside diameters of pipe as given in ASME B36.10M for standard wall pipe. Thickness of standard wall is the same as Schedules.

(5) To be specified by the Purchaser.

(6) 2.0 mm (0.06 in.) raised face for Class 150 and 300 raised face flanges
