Product Details

Product Name: welded joints Connector specifications: ZG1/4- 14, ZG3/8- 14, ZG1/2- 14, 1/4NPT- 14, 3/8NPT- 14, 1/2NPT- 14,1 /2NPT-M20*1.5-14*3 Material: 20#, 201, 304, 316, 321, 316L Withstand voltage: 1.0-32MPA, temperature resistance: -20-500°, pipe diameter 6MM-25MM, etc. :M,ZG,G,ZM,NPT,PT,BSPP,BSPT,R,RC,Connection: Butt-welded, welded, threaded, ferrule-welded product alias: transmitter connector, pressure gauge connector , stainless steel air source connector, pressure pad type straight through union, instrument joint, butt welding straight joint, butt welding joint, differential pressure transmitter joint, instrument valve joint, needle valve welding short tube, instrument air source Connector , Transition joints, conversion instruments and other joints. Generally, the normal specification is the form of PTFE pressure pad seal. The hydraulic pressure is generally JB/966, and the JB/T970 cone seal standard is JB/T6381.
1, JB/T6381.2. JB/T6381.3, JB/T6381.4 Sealing form: PTFE pressure pad type, copper pad seal, cone seal, flat O-ring seal, spherical hard seal, etc. 1/2NPT(M)-M20*1.5/14 Butt welding type through terminal joints Uses: Widely used in electric power industry, electromechanical engineering, chemical engineering, mechatronics, shipbuilding, auto parts, metallurgy, various gas sources Pneumatic, hydraulic piping, pressure gauge connection piping, differential pressure transmitter connection piping. A simple summary of the form of the pressure gauge joint:
1, butt welding pressure gauge joint: This is a nut plus a welded short tube, the form of the joint, the general form M14 * 1.5-φ8, M20 * 1.5- Φ14,
2, M22*1.5-φ16, M24*1.5-φ18, this pressure gauge is actually the welding instrument connector of the instrument needle valve. 3, Butt welding type straight terminal joint: one external thread ZG1/2, 1/4NPT, 3/8NPT, 1/2NPT, one end with live joint welding short tube, this joint is often in each gas source pipeline Application, applied in the connection pipeline of differential pressure transmitter, so it is also called stainless steel air source joint, transmitter joint, etc. 4, hexagonal inner and outer wire form, one end is inner wire, one end is outer wire, commonly used in The application of pressure gauge pipe, also called instrument conversion joint, pressure gauge joint, internal and external wire pressure gauge joint, stainless steel adapter, etc., conversion form can realize the conversion between various thread forms. 5, the inner pressure gauge connector of the pipe, the joint is essentially a pipe inner wire, M14*1.5, M20*1.5, G1/2 inner wire is often connected with the pressure gauge 6, the ferrule type pressure gauge joint The joint is an internal thread M14*1.5 or M20*1.5, and the first one is a ferrule type connection. The diameter of the tube of the ferrule is generally 6MM, 8MM, 10MM, 14MM, 18MM, etc. The company can customize various air source joints. , pneumatic joints, butt-welded pressure gauge joints, ferrule-type pressure gauge joints, hexagonal internal and external wire conversion pressure gauge joints, pipe internal pressure gauge joints, quick-connect joints, butt-welded straight-through terminal joints.
