ANSI/ASME B16.25 standard specification

ANSI/ASME B16.25 is the standard covers the preparation of butt welding ends of piping components to be joined into a piping system by welding. The standard includes the butt welding ends information of General scope, Welding Bevel designs, Preparation of inside diameter of welding ends and the tolerances involved. ANSI/ASME B16.25, Buttwelding Ends Following are the dimensions of the butt welding pipe ends according to ANSI B16.25. It includes requirements forwelding bevels, for external and internal shaping of heavy-wall components, and for preparation of internal ends (including dimensions and tolerances). Coverage includes preparation for joints with the following: (a) no backing rings (b) split or noncontinuous backing rings (c) solid or continuous backing rings (d) consumable insert rings (e) gas tungsten arc welding (GTAW) of the root pass Details of preparation for any backing ring must be specified when ordering the component. ANSI/ASME B16....

ANSI Flange Standards

The American National Standard Institute, ANSI, has been overseeing guidelines and standards for products manufactured through several sectors. WHAT IS ANSI? ANSI-approved flanges are used for the industrial market which handles gas, air and steam process systems. Originally formed in 1918, the American National Standards Institute is headquartered in Washington, DC, and is widely recognized as the American organization responsible for overseeing the national standards and conformity assessment system for products, services, processes, systems, and personnel. ANSI works domestically with American government agencies and organizations, as well as with international entities, to make ANSI standards useful around the world. Prior to the creation of ANSI, standards for engineering and equipment such as flanges were developed by the American Institute of Electrical Engineers (AIEE or IEEE), the American Society of Mechanical Engineers (ASME), the American Institute of Mi...

Large diameter elbow

Large diameter elbow is curved connecting pieces that join straight lengths of pipe, commonly at a 90° or 45° angle, allowing obstructions to be avoided in plumbing, ventilation, welding, and automotive applications. ASME B16.9 Standard covers overall dimensions, tolerances,ratings, testing, and markings for factory-made wrought buttwelding fittings in sizes NPS 1⁄2 through NPS 48 (DN 15 through DN 1200). Size range: 20 "-62" Inch Wall thickness: Sch5-Sch160 XXS Material: Carbon steel: ASTM A234 WPB, WPC, ASTM A420 WPL1, WPL3, WPL6, WPHY42, 46, 52, 56, 60, 65, 70 Alloy steel: ASTM A234 WP1, WP12, WP11, WP22, WP5, WP7, WP8, WP91 API5L X42 X52 X56 X60 X65 X70 X80 Stainless steel: ASME A403 WP304, 304L, 316, 316L, 310 Standards: ANSI, DIN, JIS, GB, ASTM, JB, SH, YB, SY, HG, API ASME Usage: Petroleum, chemical, power, gas, metallurgy. Our pipe elbows are widely used in many industries, such as power generation, petroleum, natural ga...
