I. INTRODUCTION A study was performed to provide bending moment ratings as a function of internal pressure for five API clamp-hub combinations and for a heavy duty 18 3/4-10 connector, designed to withstand a one million ft·lb bending moment at working pressure. The design of the...
This standard covers methods, process requirements, tolerances and acceptance criteria for shop fabricated pipe bends. The bending methods described in this standard are a partial representation of commonly used processes and do not preclude the use of other methods.
1.1 This test method covers a procedure for determining the long-term ring-bending strain (Sb) of "fiberglass" pipe. Both glass-fiber-reinforc
5.1 This standard practice is a procedure to evaluate the ductility of side bend test specimens that are a transverse section of the pipe wall and butt fusion. Side bend test specimens are prepared from bend test coupons from sample polyethylene pipe butt fusion...
This Def Stan details the procedures and requirements for the bending of metallic pipes for all services except those used in reactor plant systems in nuclear submarines.
5.1 This test method is designed to rank material couples, surface treatments, and lubricants by CFT and in their resistance to adhesive wear. Since adhesive wear is a complex phenomenon and stochastic in nature, it is essential to evaluate surfaces to confirm the presence of adhesion. 5.2 This...
This specification covers high-silicon iron pipe and pipe fittings intended for corrosion-resistant service for both above- and below-grade construction. The castings shall be true to pattern, reasonable smooth, and free from defects that would make the castings unfit for the use for...
1.1 This specification2 covers heavy-wall carbon and alloy steel pipe (Note 1) made from turned and bored forgings and is intended for high-temperature service. Pipe ordered under this specification shall be suitable for bending and other forming operations and for fusion...
1.1 This specification2 covers nominal wall and minimum wall seamless ferritic alloy-steel pipe intended for high-temperature service. Pipe ordered to this specification shall be suitable for bending, flanging (vanstoning), and similar forming operations, and for fusion welding...
This specification covers requirements and test methods for fabricated poly(vinyl chloride) (PVC) plastic schedule 40 drainage and DWV fittings. These fabricated fittings are manufactured from pipe, or from a combination of pipe and injection molded parts. Resistance to bending...
1.1 This specification2 covers nominal wall and minimum wall seamless ferritic alloy-steel pipe intended for high-temperature service. Pipe ordered to this specification shall be suitable for bending, flanging (vanstoning), and similar forming operations, and for fusion welding...
This specification covers wrought welding fittings, including threaded fittings, for pressure piping, factory-made from nickel and nickel alloys. The term welding applies to butt-welding or socket-welding parts such as elbows, bends, caps, tees, reducers, lap-joint, and stub ends. This...
1.1 This specification2 covers seamless and welded black and hot-dipped galvanized steel pipe in NPS 1/8 to NPS 26 [DN 6 to DN 650] (Note 1), inclusive, with nominal wall thickness (Note 2) as given in Table X2.2 and Table X2.3. It shall be permissible to furnish pipe having other...
1.1 This specification2 covers electric-resistance-
4.1 The inspection of installed reinforced concrete pipe verifies proper installation of the product and establishes thresholds for comparison further evaluation. 4.2 This practice is useful as a reference by an owner in preparing project specifications and to identify, evaluate and...
