• It uses a non-consumable tungsten electrode to create the weld.

• TIG welding produces high-quality, clean welds with minimal spatter.

• The process allows for precise control over the welding ar...read more

Cleaning pipe lines involves various procedures such as flushing, pigging, and chemical cleaning.

• Flushing involves using water or air pressure to remove debris and buildup from the pipes.

• Pigging uses a device called a 'pig' to scrape the inside of the pipe and push out any blockages.

• Chemical cleaning involves using specific chemicals to dissolve and remove stubborn deposits in the pipes.

• Regular maintenance and inspecti...read more

NAS value is a measure of network-attached storage performance and reliability, important to achieve within standard limits for optimal data storage and access.

• NAS value stands for Network-Attached Storage value, which measures the performance and reliability of a storage system.

• It is important to achieve NAS value within standard limits to ensure optimal data storage and access speeds.

• Exceeding NAS value limits can re...read more

Conveyor alignment is done by adjusting the idlers and pulleys to ensure the belt runs straight and centered on the conveyor frame.

• Check for any misalignment by observing the belt's position on the idlers.

• Adjust the idlers and pulleys to ensure the belt runs straight and centered.

• Use alignment tools such as laser alignment devices for precision.

• Regularly inspect and maintain the conveyor system to prevent misalignment ...read more
