Step to repeat. If lifting lugs are welded to a reinforcing pad, and the pad is connected to the shell with fillet welds, then the capacity of the lifting lugs is a function of the strength of the pad fillet welds, as well as the fillet welds attaching the lug . The ball valve on the air pump or air compressor or Nitrogen bottle . R-pads are also known as reinforcing . With the increase in pipe size, the cost of branch connection fittings increases. The . In B31.3 and CAESAR, the "reinforced" type is a hole cut into the header pipe, the end of another pipe trimmed to fit the hole, and then a reinforcement pad is added and all components welded together. on each side of the center line of the branch pipe and those dimensions.

The leveling pad shall have minimum nominal dimensions of 6 inches thickness and 12 inches width, and shall be cast using minimum 2,000 psi 28-day compressive strength concrete. Also known as repad or weld pad. Multiply the measurements from Step 1 and Step 2 together. There are many types of meshes used in construction (like carbon and fibre), though steel mesh is the most common and cost-effective. The size and positions of strip footings are usually proportional to the width of the wall structure. However, even when that reinforcement is required, it can be furnished by excess plate thickness and/ or nozzle neck area, and AWWA never specifically requires a reinforcing pad.
