Pipe Ends
*Threading
NPT (National Pipe Thread) and BSPT (British Standard Pipe Thread) are two commonly pipe thread standards.
NPT threads are commonly used in North America and BSPT threads are more commonly used in Europe and Asia.
Both standards have tapered threads that create a tight seal when tightened together. Widely used in water, gas, oil and other pipelines connection.
2. Fixing of steel pipes: It is also a common application to fix steel pipes to walls or other surfaces through the steel pipe drilling process.
*Grooved
Roll Groove connection is a popular method of connecting fire protection pipes because it offers many advantages. Here are some of the main benefits:
1. Convenient and fast installation: Roll Groove connection allows for quick and easy installation of pipes and fittings, as there is no need for welding or threading.
2. Economical and environmental protection: This connection method is more cost-effective than other methods, making it a popular choice for many applications. It is also environmentally friendly as it reduces waste and uses fewer resources.
3. Preserves the original characteristics of the pipes: Roll Groove connection does not affect the original properties of the pipes, such as their strength, durability, and resistance to corrosion.
4. Maintenance is convenient: If maintenance and repair are needed, Roll Groove connection makes it easy to disassemble and replace components, without requiring any specialized tools or equipment.

*Plain Ends
Cutting both ends of steel pipe into planes at 90◦ to the axis is a common requirement in many industries where the pipes are used. This is usually done to prepare the pipe for welding or other types of connections, and ensure that the ends are flat and perpendicular to the pipe's axis.
*Flanged
A flanged steel pipe is a type of pipe that has a flange attached to one or both ends. Flanges are circular discs with holes and bolts that are used to connect pipes, valves, or other equipment. The flanged steel pipe is usually made by welding a flange to the end of a steel pipe.
Flanged steel pipes are commonly used in industries such as water supply, oil and gas, and chemical processing. They are preferred over other types of pipes because they can be easily installed and are highly durable. Flanged pipes can withstand high pressure and can be easily disassembled for maintenance or repair.
The flanges on a flanged steel pipe come in different shapes and sizes to match the connection requirements. Common types include slip-on flanges, weld neck flanges, threaded flanges, and socket weld flanges.
In summary, flanged steel pipes are a popular choice for many industries because they provide a reliable and durable connection between pipes and equipment.
*Cutting Length
Water cutting technology is known for its precision and accuracy, as well as its ability to produce smooth, burr-free edges.
One of the major advantages of water cutting technology is that it is a cold cutting method, meaning that there is no heat-affected zone (HAZ) around the cut.
Water jet cutting is also environmentally friendly, as it does not produce any hazardous waste or emissions. The system uses only water and abrasive, and the waste products can be easily collected and disposed of safely.
