Product Description:

API STC Casing Couplings

We provide STC casing coulings from 4-1/2″ to 20″, in grade J55, K55, N80, L80 and P110.

Threads are used as mechanical means to hold the neighboring joints together during axial tension or compression. For all casing sizes, the threads are not intended to be leak resistant when made up.

The round-thread (STC or LTC) casing-joint strength is given as the lesser of the fracture strength of the pin and the jump-out strength.

Q:Will the moving angle of the air conditioner indoor be harmful to the connecting pipe joint?
It will not affect the joint, but it is possible to take care of the brass pipe and bend it or make it straight.
Q:What is the difference between the pipe and the pipe joint?
A metal tube 1, ordinary carbon steel wire (wire casing pipe) 2, metal flexible pipe (galvanized pipe, stainless steel pipe, plastic coated metal snakeskin snakeskin tube)
Q:How about the water pipe fittings and millimeters?20mm is 425mm is 6Why
20mm is not a scientific argument.Should be the plastic pipe, the nominal outer diameter of DN20 plastic pipe, only corresponds to 4 points of the metal pipe threadThree,If it is a metal tube, it should be nominal diameter Dn15, and the corresponding English pipe thread is 6
Q:How much is the monofilament of the 304 pipe joint?
If it is conventional, the basic can be connected, Sheng Jiang Industrial products have such joints, called water pipe joints
Q:How was the pipe joint named?
Hydraulic hose, high pressure ball valve, special quick joint, clip type pipe joint, welded pipe joint, high pressure hose. Transition type pipe joint, clamp type pipe joint, three type pipe joint, non-standard pipe joint, flared pipe joint, right angle pipe joint, rotary pipe joint, quick joint, stainless steel pipe joint and copper joint.Welded pipe jointPipe welding with nozzles. The sealing surface of the O sealing ring is sealed between the joint body and the pipe. The utility model has the advantages of simple structure, easy fabrication, good tightness and low requirement for the dimension precision of the pipe. High welding quality, inconvenient assembly and disassembly. The working pressure is up to 31.5MPa and the working temperature is -25 to 80 DEG C. It is suitable for the piping system with oil as the medium. Table 6~14 JB966 to 1003-1977
Q:The pipe line of the hydraulic pressure pipe is formally installed
Three. Threaded pipe threads (GB 7306 is the same as ISO7/1)1. thread sealed pipe threads, without padding or sealing, can prevent leakage. The pipe thread with screw thread has two connecting forms: cylindrical internal thread and tapered outer thread, tapered inner thread and tapered outer thread. When the pressure is below 5 * 105Pa, the former connection is close enough, and the latter connection is usually used only at high temperature and high pressure.2. thread sealed pipe thread, there are two kinds of thread cone, cylinder. The external thread has only one form of taper. Tooth type is as follows: taper 1:16, tooth shape angle 55 degrees, old thread standard example: ZG3/8;
Q:Drawing design, drain cross dry pipe is flexible cast iron pipe, vertical pipe is PVC pipe joint
The transverse drain pipe is a flexible cast iron pipe. The vertical pipe is PVC pipe joint. When it needs to change the diameter, it is most suitable to use a special AD type bottom joint.
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:Hydraulic tubing connections are made of material steel
Such as carbon steel and cast iron, a much more used, less material costsBut if you're under a lot of pressure, try using carbon steel
Q:What joints do nylon hard tubes work on?
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.There are three kinds of hard tube joints: flaring, clamping and welding
