Why is filet weld necessary while welding slip on flanges to a pipe end?
It is the only type of weld you can make to seal this type of joint. There are flange ends that can be welded onto pipe with a butt weld, but sockets and slip-ons must be fillet welded.
What is the minimum weld required on weldolets have welded a CS as the main run pipe is of less thickness?
To be fully welded out plus a fillet of @ 6mm to reduce the stress concentration factor at the bottom toe.
What is the difference between a Butt weld and a socket weld?
A butt weld is where the diameter of the pipes welded together are the same, a socket weld is where a larger diameter pipe is fitted into a smaller one. In making a butt weld, the pipes (or pipe and fitting) usually have an angle machined or ground into the outside corner, so when they are placed together face-face, there is a circumferential V shaped gap serving as the weld prep. In a socket weld, the pipe is inserted into the socket, backed off slightly to make a gap between the end of the pipe and the bottom of the socket, and the weld is made around the outside diameter of the socket to the outside diameter of the pipe. The gap at the bottom of the pipe prevents thermal expansion from stressing the joint during or after welding.
What is Socket weld?
A socket weld is a pipe attachment detail in which a pipe is inserted into a recessed area of a valve or fitting, and then fillet welded between its outside diameter and the fitting end. Generally used for piping whose nominal diameter is 2 inches (50 mm) or smaller.
How can one weld a flange tight?
One would weld a flange tight by firstly establishing which type of joint they were welding. One of the most common is welding a neck flange. For this you would need to ensure that both pieces of material to be welded are melted on the first bead of the weld. You would continue around the pipe until you reach the beginning. Once back at the start you need to ensure that the final bead is higher than the joint being welded. The weld should be approximately 1/16th of and in to 1/8th of and inch from the pipe to the flange.

What the difference between weldolet and thredolet?
A weldolet is a fitting you weld on a (run) pipe, and then butt weld a branch pipe to it. A tredolet is a fitting you weld on a (run) pipe, and then screw a threaded branch pipe to it. Some people call this a threadolet A sockolet is a fitting you weld on a (run) pipe, and then socket weld a branch pipe to it. A nipolet is the same as a weldolet or thredolet but has an elongated branch connection. You have to specify if it's a welded or threaded nipolet.
What is the past tense of weld?
The past tense of weld is welded.
What is furnace butt welded pipe?
Furnace butt welded pipe refers to the manner in which a pipe is to be welded. The skelp itself is heated to a specific temperature in a furnace. You would then weld the longitudinal seam forge. This is a method that works on fence posts or pipes required for low pressure services.
6 inch weldolet welded to 12 inch pipe what is the inch dia involved?
The meaning of dia inch is the number of weld joints multiplied by the dia of a given pipe size, since the weld joints is on the 6" pipe, the calculations should be 1 weld x 6" = 6 dia inch.
how do weld GI pipe to GI pipe?
A GI pipe is welded to a GI pipe by using solder and flux. The pipe is heated up, flux applied, and then solder allowed to flow into the joints to create a secure bond.
Difference between weldolet and sockolet in piping?
Weldolet has a Bevelled end to butt weld the pipe whereas in sockolet the pipe/tube goes inside it and there it is fillet welded.
What is the minimum weld required on weldolets have welded a CS as the main run pipe is of less thickness?
To be fully welded out plus a fillet of @ 6mm to reduce the stress concentration factor at the bottom toe.
What type of weld for a sockolet?
A sockolet is typically welded using a socket weld. This type of weld is ideal for connecting a branch pipe to a main pipe, providing a strong and reliable joint. The socket weld involves inserting the branch pipe into a recessed area of the sockolet and then welding around the joint to ensure a secure connection. It's commonly used in high-pressure and high-temperature applications.

What is helically submerged arc welded pipe?
Helically submerged arc welded (HSAW) pipe is a type of steel pipe produced using a welding process where the steel strip is formed into a pipe shape and then welded along a helical seam. The submerged arc welding technique involves feeding a granular flux over the weld area, which protects the molten weld pool from contamination and improves the quality of the weld. HSAW pipes are commonly used in various applications, including oil and gas transportation, water supply, and structural applications, due to their strength and durability. Their manufacturing process allows for the production of large-diameter pipes at high speeds.
What is Socket weld?
A socket weld is a pipe attachment detail in which a pipe is inserted into a recessed area of a valve or fitting, and then fillet welded between its outside diameter and the fitting end. Generally used for piping whose nominal diameter is 2 inches (50 mm) or smaller.
