Extended couplings for oil field tubing

Tubing coupling is a type of drilling tool used in oil fields, mainly for connecting tubing.

Tubing couplings are a type of drilling tool used in oil fields, mainly for connecting tubing and solving the problem of fatigue and fracture caused by stress concentration in existing couplings.

The structure of the oil pipe coupling is:

The end of the oil pipe is connected to the inner wall of the coupling body with a conical thread, and the end of the coupling body is connected to the oil pipe with a flat thread of the same thread and pitch. It has the characteristic of relieving stress concentration at the root of the external thread of a single cone thread connected oil pipe, making it less prone to fatigue fracture and achieving good connection effect. Effectively prevent the occurrence of oil well string breakage accidents.

Couplings are divided into tubing couplings and casing couplings.


The main characteristics of petroleum couplings include corrosion resistance, high temperature resistance, and wear resistance. Oil couplings are commonly used in oil extraction environments such as oil wells and geothermal wells, and have high corrosion resistance and high temperature resistance, which can adapt to harsh working environments.

Q: What are the commonly used hardware materials? What are their respective properties?
Hardware is a kind of building materials industry, including construction hardware, mechanical hardware, spraying equipment, kitchen facilities, bathroom facilities and hardware fittings.The traditional hardware refers to hardware, refers to iron, steel, aluminum and other metal, through forging, calendering, cutting, and so on physical processing made from various metal devices. There are many kinds of hardware products, and the specifications are not the same. They occupy an important position in furniture decoration.Big hardware includes steel plate, steel, flat iron, steel bar, universal channel iron, I-iron and various types of hardware, building hardware, tin, lock nails, wire, steel wire, steel wire cutting, home hardware, tools etc.. On the nature and use of hardware, iron and steel materials, non ferrous metal materials, machinery parts, transmission equipment, auxiliary tools, working tools, construction hardware, household hardware and other eight categories are to be considered.
Q: Hardware stamping materials, know to tell me, the more species, the better, thank you ~!
Steel, steel, alloy, stainless steel, brass, aluminium, zinc, copper and ironSome other good plastic alloys can also be used as hardware stamping materials
Q: What does hardware refer to? What's the use?
[hardware] traditional hardware, also known as "hardware", refers to gold, silver, copper, iron, aluminum, five kinds of metal, processed by artificial, can be made into knives, swords and other art or metal devices. Modern society is more widely used in hardware, today's hardware is often used as a metal or copper, iron and other products collectively. Such as hardware tools, hardware parts, daily hardware, construction hardware and security supplies. Most hardware products are not consumer goods.[hardware use] hardware products, appear in economic life, political life and military activities in every corner. Hardware products of various types, specifications vary, but hardware products in modern life also plays an irreplaceable role in the choice of good hardware fittings, can make many structural parts more safe and convenient to use.
Q: How do you do the hardware business?
Learn to take advantage of. For small and medium enterprises but linked to large orders can find some idle plant or equipment, in order to save the cost of investment, only need to put technology and human resources, so you can earn more profit. Once there is a market crisis, we can flexibly do a good job of market transformation, so as to avoid blind expansion.
Q: What kind of hardware do you have?
Hardware, traditional hardware, also known as "hardware"". Refers to iron, steel, aluminum and other metal, after forging, rolling, cutting, and so on physical processing made from various metal devices. Such as hardware tools, hardware parts, daily hardware, construction hardware and security supplies. Most hardware products are not final consumer goods. It is made as an industry...
Q: Please tell people where can to buy genuine hardware accessories?
To hardware mall, to the regular store. Distribution of various brands of shops.
Q: What do hardware mainly do?
Hardware: traditional hardware, also known as "hardware"". Of five metals: gold, silver, copper, iron, and aluminum. By artificial processing, you can make knives, swords and other art or metal devices. The hardware of modern society is more extensive, such as hardware tools, hardware parts, daily hardware, construction hardware and security products. Most hardware products are not final consumer goods.Many kinds of hardware products, different specifications of hardware products, but in the Home Furnishing decoration also plays an irreplaceable role, choose a good hardware accessories can make a lot of decoration materials use more safe and convenient. Actually, there are more than ten kinds of hardware products in the materials market.
Q: How do hardware stores feature?
Many people in your small electric gas. Older goods. You must remember that you must do is store business integrity then you can repeat. Repeat in your business for Billy in 60%. These two people to be honest. In short. The goods better.
Q: Does hardware affect the tightness of doors and windows?
Wind is one of the major climatic factors in the design of doors and windows. Wind is the motive force of doors and windows deformation, damage, cold air infiltration, rain seepage, and blocking entry into buildings. Therefore, the performance of building doors and windows has the requirements of wind pressure resistance, air tightness and water tightness.Building doors and windows because of the different geographical position, the height of buildings of different factors and the installation of doors and windows position may have positive pressure, negative pressure or positive and negative wind pressure alternation, when subjected to wind pressure is large it may cause serious deformation, broken glass, doors and windows hardware damage, cause the sash fall phenomenon caused by accidents, especially the typhoon area, should pay more attention to high-rise building outside the window due to wind load damage problem.
Q: What does hardware and electrical appliances include?
Traditional hardware, also known as "hardware"". Refers to iron, steel, aluminum and other metal, after forging, rolling, cutting, and so on physical processing made from various metal devices. Such as hardware tools, hardware parts, daily hardware, construction hardware and security supplies. Most hardware products are not final consumer goods.
