Q:Re series 24 degrees cone O ring seal pipe joint joint, corresponding to the national standard number is?
The pipe joint is the connecting tool between the pipe and the pipe, and it is the connection point between the component and the pipe. It plays an indispensable role in pipe fittings. It is one of the two main components of hydraulic pipe. The [1] pipe joint is used for straight connection such as instrument, and the connection form is socket welding or threaded connection. It is mainly used in low pressure pipes with small diameter, used for parts that need to be packed frequently or used as final adjustment of threaded pipe fittings. Fast and easy and related products were included, should adopt the structure of metal surface contact sealing structure, structure of gasket seal is usually used for conveying water, oil, air and other general pipeline, the use of malleable cast iron material. In addition, the use of requirements and prices are also factors to consider when selecting.
Q:What's the difference between the half pipe joint and the branch seat?
The 1. half pipe joint standard half pipe joint specification production pipe connection form the connection form is divided into three kinds of socket weld connections, welded connections, threaded connections. Pressure rating: pipe pressure rating, general socket welding, butt welding fittings form the pressure rating of 3000LB (SCH80), 6000LB (SCH160), 9000 (XXS). Thread connection type, pipe pressure grade is divided into 2000LB, 3000LB, 6000LB. The commonly used pipe Name: 90 degree elbow, three, four, 45 degree oblique three, couplings (pipe joints, and copy), half coupling (half pipe joints, pipe cap, semi Bele), Union (by either), Taiwan Branch (branch block). The power plant took over the seat, forged three, threaded plug, the wire, bushing, strengthening pipe joint pipe.
Q:The expansion type pipe joint and the sleeve type pipe joint difference, everybody looks at the picture, this is belongs to that kind of?
Sleeve type pipe joint: the working principle of the clamp sleeve is to insert the steel tube into the clamp sleeve, lock the sleeve with the nut, contradict the sleeve and cut into the pipe to seal. The utility model does not need welding when connected with the steel pipe, and is favorable for fire prevention, explosion prevention and high-altitude operation, and can eliminate the defects caused by careless welding. Therefore, it is a kind of advanced connecting device in pipeline, automatic control device, pipeline, oil refining, chemical, petroleum, natural gas, food, pharmacy, instrument and meter, etc.. Apply to oil, gas, water and other medium pipeline connection. The card connector has reliable, high voltage capability, high temperature resistance, good sealing and repeatability, installation and convenient maintenance, safe and reliable connection.
Q:What's the difference between pipe repair device and clamp type flexible pipe joint?
