Equations 7.12 and 7.13 are slightly different in form because of the different types of piping systems each is intended to cover. In Equation 7.13, no special provision is made for corrosion or thread allowance. Most gas distribution systems are large-diameter, welded pipe. ASME B31.8 does not...
(inside diameter) are explored, as well as the three systems of weight, schedule, and measurement to determine a pipe’s wall thickness. Butt-weld, threading, and socket-weld methods ofjoining pipesare explained and detailed. The uniqueness ofcast iron pipeand its two basic types of ...
to form an external conical shoulder whereby, when the pin and box member are threadably connected, the overhang or lip 31 overlies the end 40 longitudinally of the joint to prevent the box end from spreading under excessive torque or make-up strain, all as explained in the aforementioned pa...
13. The method of manufacturing a single piece of thermoplastic pipe as recited in claim 8 wherein said reinforcement band extends beyond a last thread of said internal thread, in a direction opposite said female leading edge. 14. The method of manufacturing a single piece of thermoplastic pipe...
In 1939 API adopted the 8Rd thread connection to connect joints of API tubing and casing, which is still used to connect about 80% of well pipe today. My U.S. Pat. No. 5,427,418 filed in 1992 explained why API 8Rd Connections loosen and leak, and “API Item 2239 Work Group” di...

Ferritic stainless steel types are not explained since they are not common in the oil and gas industry. Martensitic stainless steels Martensitic stainless steel grades that are used for industrial valves in the oil and gas industry are normally 13Cr, 13Cr-4Ni, or 17-4 PH. These materials ...
In this chapter, 45° elbows, straight and reducing tees, and stub-ins are explained. Other types of fittings used to make branch connections, such as unions, couplings, weld-o-lets, sock-o-lets, thread-o-lets, latr-o-lets, and elbow-lets, are presented. Concentric and eccentric ...
However, due to the weight of these tubular members, such relatively uncontrolled handling can result in damage to thread connections, and also because of the inordinate amount of manual handling which is required, can result in injury to workers at the well site. Considerable attention has ...
