What thickness would be used to determine whether heat treatment of this connection is required? (Express answer to nearest hundredth.)ĭ. The material of the branch and the header is ASTM A 106 Grade B. The branch connection is inserted into the header. A ¼” reinforcing pad is used around the branch connection. An NPS 4 Schedule 40 (0.237” wall) branch connection is welded into a NPS 6 Schedule 40 (0.0.280” wall) header. That of the thinner component measured in the thinner pipe except exclusions. That of the average thickness of the two components, except for certain exclusions.ĭ. That of the thicker component measured at the joint, except for certain exclusions.Ĭ. That of the thinner component measured at the joint, except for certain exclusions.ī. When components of a piping system are joined by welding, the thickness to be used in applying the heat treatment provisions of ASME B 31.3, Table 331.1.1 shall be:Ī. An ASME A 106 Grade B, NPS 8, Schedule 40 (0.322” wall) pipe is to be welded to an ASME A335 Grade P9, NPS 8, Schedule 40 (0.322” wall) pipe. At a minimum 2” each side of the weld 17. At least 1” beyond each edge of the weldĭ. At least ½” beyond each edge of the weldī. What preheat temperature, if any, is required.ĭ. An NPS 8 schedule A NPS 8 Schedule 40 (0.322” wall), ASTM A 106 Grade B, is to be welded. What size cover fillet weld (tc) is required around the fully penetrated groove weld of the branch into the header? (Express answer to nearest hundredth)ĭ. A NPS 2 schedule 80 (0.218” wall) is welded into a NPS 6 Schedule 40 (0.0.280” wall) header. What is the maximum slope of the taper bore?ĭ. The thicker pipe is taper bored to facilitate the fit up. A thicker wall pipe is joined to a thinner wall pipe.
What is the minimum energy requirement for this material (average for 3 specimens-fully deoxidized steel)?ĭ. A carbon steel ASTM A 53 Grade B material is being impact tested. Each set of impact test specimens shall consist of _ specimen bars.ĭ. What minimum temperature can it be used and not have an impact test?ĭ. An ASTM A53 Grade B pipe with a maximum wall thickness of 0.75” is being considered for use in a cold service. For a liquid thermal expansion relief device which protects only a blocked-in portion of a piping system, the set pressure shall not exceed the lesser of the system test pressure or _% of design pressure.ĭ.
They can be locked or sealed in both the open and closed positionĭ.
The valves are approved by the jurisdictionĬ. Stop valves are allowed on the inlet and outlet side of a pressure-relieving device, provided:Ī. Poisson’s ratio may be taken as _ at all temperatures for all metals.ĭ. What is the modulus of elasticity of carbon steel material (carbon content ≤ 0.3) at 700☏?ĭ. If 4 materials, carbon steel, 18Chr-8Ni, Monel, Aluminium are heated from 70☏. A 20’ long carbon steel pipe is heated uniformly to 450☏ from 70☏.
