Product Description:


Inside BOP


In all size


API 7-1


The Inside BOP is heavy-duty drop check valve with a conical plug to reduce the cutting action of the mud on the valve seat, ensuring positive closure whenever required.


Installed in the drill string, it can protect the rotary swivel, rotary hose, stand pipe, and mud pumps from drill pipekicks.


It may be used along with high pressure pumps to maintain well control by preventing high pressure backflow.

Q:What are the installation requirements of the card sleeve joint?
(1) pre assembledThe pre assembly of the sleeve type pipe joint is the most important step, which directly affects the reliability of the seal. Special pre assemblies are usually required. The small diameter can be pre joint in a vise. The concrete method is to use a joint body as the mother's body and press the nut and the sleeve tightly onto the pipe. The utility model mainly comprises a sleeve type through pipe joint, a clamping sleeve type end through connection head, a clamping sleeve type three way pipe joint and other patterns. The author found that even if the same batch of goods of the same manufacturer, the tapered holes on these joints are often different in depth, resulting in leakage, and this problem is often overlooked.The correct approach should be to connect the end of the pipe with what kind of joint body, and the corresponding connection end with the same type of joint pre installed, so as to maximize leakage problems can be avoided.
Q:What do you mean by pipe fittings 3/4?
Pipe fittings 3/4 refers to the pipe fittings of six points (6 British points), DN (diameter) of 20mm, the outer diameter of 26.8mm.
Q:Principle of fast pipe joint
Quick change joint, one is with one-way valve, and the other is without one-way valve.
Q:Maintenance skills of fire hose clamp joint leakage
The best approach is to remove the clamp groove on the inner wall of the groove, cut a layer of 3mm thick rubber (or thin rubber inner tube), the inner wall of the groove width is smaller than the width of about 2~3mm, their good after the clamp bolt is good, no Water Leakage the problem.
Q:PT3/4 what is the diameter of the pipe joint?
Diameter: Phi 23.6 mm.Taper Pipe Thread is an inch taper pipe thread standard. Threaded pipe threads (GB 7306 and ISO7/1).
Q:How should thread thread be broken in the joint?
2, in the broken wire head to open a groove or welding nut go up, screw out the broken wire.3, the broken wire will be drilled directly.4, the electric spark will break the wire destroyed.
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:PEX floor heating pipe fittings and fittings are aluminium plastic pipes?
4., antistatic, easy to flammable fluid delivery;5. good electromagnetic shielding performance;6., good flame resistance, to achieve GB8624 refractory (B1) level;7. good insulation performance.(two) hydraulic performance of aluminum-plastic composite pipe inner surface roughness of thin wall excellent, very smooth, fluid friction resistance is small, no fouling phenomenon which affects the flow of water flux than the metal pipe, and because it has a certain flexibility, can effectively reduce the water supply of water hammer and fluid pressure shock and noise.
Q:What is a slot type mechanical joint?Copy search
The groove type mechanical joint is a kind of pipe connection method that was developed in 1997. It can speed up the construction more than 10 times, and the reliability has reached the perfect level. Now, the fire fighting system has been adopted in this way. The rolling machine with the steel pipe processing a groove, and then the special clamp sealing ring will steel pipe and pipe fittings or two steel pipes are connected, convenient, and does not damage the galvanized layer, promotion of high,
Q:Hydraulic hose connector size 20As shown in Figure six, the angle is 71mm to the edge, 80mm to the diagonal, approximately 34mm higher
The maximum thread size is M60, but the maximum size is only 50.Press joint standards; hydraulic pipe fittings - screw thread. A standard two; classification; 1. screw internal and external threads two; 2.; according to the tooth shape can be divided into: 1) 2) 3 triangular thread trapezoidal thread; according to the 3. line number single thread and multi thread;; 4. by rotation in the direction of the left and right screw screw two, right standard; 5. by use of different points are: with the common thread, metric thread sealing pipe; two. 1. common metric screw threads; metric screw thread with a capital M, tooth type angle 2 DEG =60; 2. metric screw thread according to pitch
