What are di double flanged pipes, and how are they different from other types of pipe connections?
How are double-flanged pipes inspected and tested during their manufacture and installation?
These pipes are checked and inspected by seeing that they follow international industry standards. These industry standards are ASTM, ASME, DIN, MSS, EN, and JIS codes and standards.
These kinds of double-flanged pipes are tested during the manufacturing and installation by following these methods:
What are some common failure modes associated with di flange spigot pipe, and how can they be prevented?
Corrosion: This is the main reason for the failure of the di-flange spigot pipe. The problem of corrosion occurs when the pipe comes in contact with the air and water for a long time.
Soon, corrosion starts eating the metal itself and there are leakages in the pipes. This situation can be prevented with proper care, maintenance and coating the pipe with anti-corrosion paint.
High temperatures: When placed under extreme temperatures for a long time, the surface of the pipe becomes brittle and the pipe can burst. Hence, to ensure safety proper ventilation must be done, and use the right pipe for any condition.

What are some common flange types used in cast iron double-flanged pipe connections, and how do they differ in terms of design and application?
Slip-on flanges: It is basically a ring placed over the end of the cast iron double-flanged pipe. This type of flange slips over a pipe and hence it is known as a slip-on flange. These types of flanges are used in low-pressure type applications. This flange is used in many pipelines that carry fluids.
Weld neck flange: These socket weld flanges are only used on the outer of the pipe with one fitted weld. These weld neck flanges are not suitable for use in critical services. These types of flanges are mostly used for small bore lines. The weld neck flanges are very much prone to corrosion that’s why they are used on stainless steel pipes.
What are the advantages of using ci puddle flanged pipe connections over other types of pipe connections?
The ci puddle flanged pipes are most suitable for use in the pressure involving applications. These flanges are widely used in plumbing operations, oil and gas industries, and chemical processing industries.
These flanges are also used in joining two pipes together that can't be fitted because of their overall structural difference.
These flanged pipe connections can also be used in corrosive environments as there are no chances of leakage when these types of flanges are used.
What is the role of bolt tightening in welded flanged pipe connections, and how is the appropriate bolt torque determined during installation?
There is an important role of bolt tightening in flanged pipe connections. When the welded flanged pipe connections are used in the water mains then it is an important reason to have proper tightening of the bolt in the flanged joints. If these bolted joints are not done correctly then there are chances of leakages.
During the installation process, the appropriate bolt torque is determined by selecting from the pipe flange bolt torque chart, however, its calculation is possible. For the safety of the flanged joint pipe, the entire bolt connections must be tightened 3 times at 30%,70%, and 100% of the torque value.
