Long Weld Neck Flange Manufacturers Standards
Manufacturers of steel flanges follow specific production standards when designing or machining a flange. Dimensional tolerances and dimensions for long neck orifice flanges are covered in the American Society of Mechanical Engineers section 36 of publication B16. AMSE publication B.16 covers pipes and fittings made of steel, cast iron, cast bronze and wrought copper
Any long weld neck flange manufacturer has to follow the standards set by the American Society of Mechanical Engineers (AMES). This is to ensure that all flanges will be consistent in size, material, weight, and shape. They have to fit correctly in the pipe application.
Besides buildings and apartments, chemical and gasoline industries also use long weld neck flanges. There is a consistent change in temperatures and pressure in the water and gas sources that travel inside the pipes.
Long weld neck flanges operate when the connection pipes need to bend or go through different directions. Due to this reason, and the high pressure that occurs, long weld neck connection forging is crucial. They should be assessed to prevent damage.
Connection forging is the addition of extra long weld neck flanges to aid in better flows for the pipes.
There are various ways to configure your piping system depending on the kind of pressure changes that the pipe has to go through. Just like with manufacturing, long weld neck connection forging follows the standard of AMES.
Some examples of connections are heavy barrel, which provides more support because of its thicker size. The intermediate barrel is for more support compared to the heavy barrel. The equal barrel provides the most amount of support. It is ideal for places where the pressure and temperature changes.
LWN Application, Long Weld Neck Flange Uses
LWN steel flanges are largely used in the petroleum and chemical industries but can also be used in residential and commercial buildings where fluctuating temperatures and high stress are expected, such as a main water or gas source. Long neck steel flanges are used under conditions where line or pipe expansion creates bending or repeated changes in the pipe. Because a long neck flange is used in pressurized applications, the flange may have additional pressure connections and may be referred to as an orifice flange. The flange supports free product flow when bored to match the diameter of the pipe it will receive. Long weld neck flanges are attached using V-shaped welds known as butt welds
ANSI B16.5 Long Weld Neck Flanges, ASME B.16.5 LWN Pipe Flanges, DIN Long Weld Neck Flange
We are specialized in manufacturing high standard quality of Long Weld Neck Flanges. Long Weld Neck Flanges are widely used in special circumstances with their main advantage being that they can be attached to the pipe without welding. We are one of the leading manufacturer and supplier of steel LWN flanges in India, we can supply stainless steel, carbon steel and nickel alloy LWN flanges.
Steel flanges offer a way to secure metal pipe and prevent leaks and other damage. Choosing the right metal flange and other metal fittings is dependent upon what type of substance flows through the piping system. A steel flange called a long weld neck flange is designed to offer extra support and safety in certain high-pressure areas found in residential, commercial and industrial piping systems.
LWN flanges, steel LWN flanges are available with following specifications:
We proffer Long Weld Neck Flange pipe flanges that are being manufactured at our best services to companies in a range of industries including power generation, shipbuilding, petrochemical plants, waste water treatment plants, oil refineries, paper mills, turnkey projects and pharmaceutical plants among others.

lap joint loose flange, lap joint flange details, lap joint flange material
These flanges are always used with either a stub end or taft which is butt welded to the pipe with the flange loose behind it. This means the stub end or taft always makes the face. The lap joint is favoured in low pressure applications because it is easily assembled and aligned. To reduce cost these flanges can be supplied without a hub and/or in treated, coated carbon steel.

- Class 2500 lbs
Key Features:
- Most commonly stocked flange due to the fact that one size fits all pipe schedules.
- Fabricators can more easily cut pipe to length for slip-on flanges and their smaller thickness allows for easier alignment of bolting holes
- ASME B16.5 code limits their usage for 1500#-2500# (lbs.) applications and they are generally not preferred for high pressure temperature environments.
