7、on joint, externally pressurized Continued. REQUIREMENTS: Design and construction: Dimensions and configuration: See figure 1. Construction: Externally pressurized expansion joints shall be constructed of welded metal piping. Each unit shall be constructed with both internal and external guide rings

8、. Each unit shall be equipped with a drain port to be located on the outer shell of the unit. The design shall incorporate a totally enclosed, externally pressurized stainless steel bellows that is protected from by a heavy-walled shroud designed for full line pressure. The bellows shall be of singl

9、e-ply, or multi-ply construction. The classification of the expansion joints covered under this specification sheet are as follows: Type I - shall have corrugated bellows. Class 4 - shall be of the externally pressurized variety either single or double bellows. The bellows in class 4 expansion joint

10、s shall be designed and manufactured in accordance with the EJMA Standards. Sizes up to and including 10 inches shall be formed from seamless tubing Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-DTL-17813/4 3 or from a tube having only one long

11、itudinal welded seam. For sizes larger than 10 inches, more than one longitudinal seam is permissible. In no case will circumferential seams be accepted unless the requirements of a particular application require such construction and the design is approved by the agency concerned. Convolutions shal

12、l be symmetrical and of similar dimensions. Single or double bellows construction shall be specified in MIL-DTL-17813. Materials and finishes. Materials and finishes for the bellows and flanges shall be in accordance with MIL-DTL-17813. The Part or Identifying Number (PIN) consists of the letters M,
