WNFR Test Programs
Appearances
The surface of the WNRF flange should be smooth and free from obvious oxidation, rust, oil, or other contaminants. The connecting surface of the flange is flat, without unevenness or obvious mechanical damage.
Outer Diameter of Flanges
An important dimensional parameter of weld neck flanges. The size and geometry of the flange's outside diameter directly affect the way the flange is installed and connected.
Flange Inside Diameter
The Flange Inside Diameter of a Weld Neck Flange is the diameter of the inside of the flange, often also referred to as the flange bore or pipe caliber. The size of the Flange Inside Diameter is critical to the tightness of the flange-to-pipe connection, as it needs to match the outside diameter of the pipe to ensure a tight and secure connection.
Weld Neck Diameter
The diameter of the welded portion on the weld neck flange is also known as the weld neck diameter. The size of the weld neck diameter depends on the outside diameter of the pipe, and it matches the outside diameter of the pipe to be welded.
Hub Diameter
The Hub Diameter of a WNRF flange is the diameter of the protruding portion of the flange. The size of the hub diameter is the same as the diameter of the weld neck, which is the part of the flange that is used to connect to the pipe and matches the outside diameter of the pipe.
Bolt Hole Diameter
Bolt holes are the diameter of the holes in weld neck flanges used for mounting bolts. These holes pass through the thickness of the flange, usually part of the flange, and are used to join two flanges together to form a sealed pipe connection.
Flange Face Thickness
The flange thickness of WNRF refers to the thickness of the sealing surface of the flange, i.e. the thickness of the flat part of the flange.
If the flange thickness is insufficient, it may lead to deformation or rupture of the flange during installation or use, which may affect the sealing performance.
Total Height of Flange
The overall length of the flange, including the thickness of the flange disk, the length of the weld neck, and the length of the transition between the flange disk and the weld neck.
The overall flange height needs to match the height of other flanges or pipes in the piping system to ensure that the flanges are correctly connected to other components in the piping system.
Laser cutting method of welding-neck flange
Welding-Neck flange is not easy to deform, well sealed and widely used. It has corresponding rigid and elastic requirements and reasonable Welding-Neck thinning transition. The distance between the welding joint and the joint surface is large, and the joint surface is free from welding temperature deformation. It adopts a more complex trumpet structure, which is suitable for pipelines with large fluctuation of pressure or temperature or pipelines with high temperature, high pressure and low temperature. It is generally used for pipelines with PN greater than 2.5MPa Pipeline and valve connection; also used to transport expensive, flammable, explosive media on the pipeline.
In the process of processing, the performance parameters of Welding-Neck flange are strictly controlled in the process of consumer manufacturing and electric welding, so as to ensure the full use of effectiveness and application value in consumer manufacturing and application.
If a certain section of carbon steel flange connected pipe is damaged, it can be easily removed and replaced. In this way, there is no need to dismantle and replace all the pipe systems; under the condition of pipe maintenance and inspection, the pipe can be removed and inspected section by section.
The inspection speed and accuracy are improved. Carbon steel flange has different strength and pressure strength in application and consumption manufacturing, and can give full play to different effects and application value in application. Flange with different pressure strength will present different characteristics and advantages in application.
The high carbon steel has good plastic deformation and low compressive strength. After adding proper amount of carbon element, it will become more and more hard. The plastic deformation reduces and the compressive strength improves. The looper flange may need to bear the tension, pressure, torsion and tensile strength of the conditioner. Carbon steel flange is a good choice.
Applications of WNRF Flanges
Oil and Gas Industry
Oil and gas industries need the transportation of materials like crude oil, petroleum products, natural gas etc.the WNRF flanges are installed here to ensure the leak proof environment to avoid any accidents. MOST SUITABLE.
Chemical Processing Industry
Chemical processing industry has to work and transport many hazardous, reactive, corrosion causing chemicals.it is important to use a seal which sets reliability to the piping system in the form of WNRF flanges.
Water Treatment Industry
Transport of the water might lead to high pressure conditions.it becomes important to establish a secure connection which could withstand pressure during flow of water. VEry less incidents observed but sometimes client requires it.
Power Generation Industry
There is a need for transportation of steam, gas and other fluids in the power generation industry. Weld neck raised face flanges are installed due to ability to withstand high temperature and other extreme connections.
Transport packaging of WNRF Flange
Packaging:
Weld Neck Flanges is sleeved into plastic bag individually, ten pieces wrapped with water-proof material, bundled with nylon rope. Clear labels are tagged on the outside of the package for easy identification of the quantity and product I.D. Great care is taken during operation and transportation.
Prevent any damage.
During transportation items are tagged, packed in plastic bags and closed in carton boxes or seaworthy wooden cases.plywood case,pallet and according to customer's requirment
Marking:
Weld Neck Flanges are marked with alloy name, outside diameter, wall thickness and heat number. Additional information like standard and alloy numbers can be added on request.
Our Factory
The company currently has 3 elbow pushing machines and various types of molds. Capable of producing 1/2 "-24" seamless and slotted elbows through push production, with 6 sets of tee forming machines capable of producing tees of various wall thicknesses from 1/2 "-24". 10 sets of various types of press machines to meet the production of different types of reducer and pipe caps.
