Q:Can flared and jacketed hydraulic couplings be used as gas line couplings?
Yes, but it's not economical.Hydraulic pipe joint pressure is very high, commonly used in 16MPa, 25MPa, 35MPa several levels.
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:What material does the hydraulic pipe joint use? Carbon steel or cast iron?
Carbon steel, low carbon steel is welded joint. Medium and low pressure is no problem. 1~16mpa no problem. Medium and high carbon steel has not been used, this is not good welding.
Q:Connect with stainless steel tube with 304 stainless steel clip type pipe joint,
Because it is clamping, used for steam to consider the impact of temperature, it is not recommended for toxic, harmful, medium pressure above the high temperature gas.
Q:About thread, pipe joint standard question
For thread purposes, you are recommended to study the metric, American and American thread standards manual
Q:What is pressing type pipe joint
Belongs to a class of hose joint, joint sealing need to withholdA joint body and sleeve are generally formed
Q:How much is the monofilament of the 304 pipe joint?
This kind of pipe connection is very large, but the price depends mainly on how many sizes you want
Q:Quick plug and card sleeve joint sealing which good?
1, small;2, standard type;3, metal type;4, stainless steel type;5, flame retardant;6, compound type;7 drum type joint body combination;
Q:What is the nominal diameter of the phi 1/2 in the pipe joint?
One foot (25.4mm) is divided into eight parts, 1/4, that is, 2/8 is two in charge, 1/8 is 1 in charge, 3/8 is 3 in charge, 1/2 is 4 in charge, in order to calculate nominal diameter
Q:How to distinguish between flared pipe joint and welded pipe joint
Welded pipe joints: welded pipe joint applicable medium: oil, water, gas and other non corrosive or corrosive medium. The welding type sealing pipe joint with steel pipe specifications and flexible pipe welding, has the characteristics of reliable connection, good sealing performance, so it is widely used in oil refining and chemical engineering light industry, textile, metallurgy, aviation, defense, and ship system; also suitable for hydraulic transmission of various mechanical engineering, machine tools and other equipment pipeline. When the sleeve type pipe joint production can not meet the needs, and in the case of strong corrosion, priority can be adopted.
Rapidly developing, we could produce 1,300,000 couplings. We have passed API, and our products include all types of API 5CT. If you are interested in our products, please contact us without any hesitation. We are looking forward to establishing mutually beneficial business relationships with clients both in the domestic and the overseas markets.
