Abstract
Provided is a large-caliber thread protector, which relates to the field of thread protectors, and comprises an iron casing, a bayonet, plastic and a thread. The inner part of the iron casing is provided with the plastic, and the iron casing is connected to the plastic through the bayonet. The thread is disposed at the inner side of the plastic. A through hole is disposed in the iron casing. The iron casing is disposed at the inner side of the plastic, and the iron casing is connected to the plastic through the bayonet. The thread is disposed at the outer side of the plastic. The large-caliber thread protector is advantageous in that the pipe thread and pipe end used for petroleum natural gas can be prevented from being damaged during the normal process of loading and unloading and transporting; the screw thread can be prevented from being blended with dust and water during the transport process and the normal storing period; corrosion caused by invading or retaining of wet air can be reduced to the lowest; the structure is light, and mounting and dismounting are convenient; production and general use can be facilitated in terms of cost.
Description
Technical field:
The utility model relates to a kind of cap for the protection of steel tube screw thread and pipe end, is specifically related to a kind of threading protectors that is applicable to bigbore oil, natural fuels use steel pipe.
Background technology:
Threading protectors is mainly used in preventing the oil sky, so gas loads and unloads and damage in transit normal with gas thread and pipe end; prevent that screw thread from infiltrating dust and water with normal lay up period in transportation, help to make by wet gas invade or be detained the corrosion that causes and be down to minimum.
Known threading protectors is overall plastic structure, mainly has following defect: 1) temperature Change plastic hot distortion, and protector product size and steel tube screw thread quality of fit are uncontrollable; The high temperature threading protectors comes off, and the low temperature threading protectors can't be dismantled; 2) overall plastic threading protectors impact strength can't meet the requirement of API Spec5CT/IS011960; 3) install and need installation accessories to fix, guarantee product threading protectors in transportation does not come off; 4) large calibre threads protector size is large, and the product weight is installed, dismantles inconvenient.
The utility model content:
The purpose of this utility model is to provide a kind of large calibre threads protector; it can prevent effectively that petroleum gas from loading and unloading and damage in transit normal with gas thread and pipe end; prevent that screw thread from infiltrating dust and water with normal lay up period in transportation; help to make by wet gas and invade or be detained the corrosion that causes and be down to minimum; has lighter structure, installation, convenient disassembly.And can advantageously production and general on cost.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it comprises iron-clad 1, bayonet socket 2, plastics 3 and screw thread 4, the inside of iron-clad 1 is provided with plastics 3, and iron-clad 1 is connected by bayonet socket 2 with plastics 3, and screw thread 4 is arranged on plastics 3 inboards.
Described iron-clad 1 inside is provided with through hole 5.
The utility model iron-clad 1 is connected bayonet socket and is connected with plastics, prevent that iron-clad 1 from separating with plastics 3.Hard iron-clad 1 has good impact resistance, and plastics have good snubber impulsive force, effectively the tube head each several part of protection the inside.Large calibre threads protector through-hole structure deisgn product is lightweight, the large calibre threads protector is installed is need not annex, and a people can operate.
The utility model can prevent effectively that petroleum gas from loading and unloading and damage in transit normal with gas thread and pipe end, prevent that screw thread from infiltrating dust and water with normal lay up period in transportation, help to make by wet gas and invade or be detained the corrosion that causes and be down to minimum, has lighter structure, installation, convenient disassembly.And can advantageously production and general on cost.
Description of drawings:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of this specific embodiment two.
The specific embodiment:
The specific embodiment one: referring to Fig. 1, this specific embodiment is by the following technical solutions: it comprises iron-clad 1, bayonet socket 2, plastics 3 and screw thread 4, the inside of iron-clad 1 is provided with plastics 3, and iron-clad 1 is connected by bayonet socket 2 with plastics 3, and screw thread 4 is arranged on plastics 3 inboards.
Described iron-clad 1 inside is provided with through hole 5.
This specific embodiment iron-clad 1 is connected bayonet socket and is connected with plastics, prevent that iron-clad 1 from separating with plastics 3.Hard iron-clad 1 has good impact resistance, and plastics have good snubber impulsive force, effectively the tube head each several part of protection the inside.Large calibre threads protector through-hole structure deisgn product is lightweight, the large calibre threads protector is installed is need not annex, and a people can operate.
This specific embodiment can prevent effectively that petroleum gas from loading and unloading and damage in transit normal with gas thread and pipe end, prevent that screw thread from infiltrating dust and water with normal lay up period in transportation, help to make by wet gas and invade or be detained the corrosion that causes and be down to minimum, has lighter structure, installation, convenient disassembly.And can advantageously production and general on cost.
The specific embodiment two: referring to Fig. 2, this specific embodiment is that with the difference of the specific embodiment one described iron-clad 1 is arranged on the inboard of plastics 3, and iron-clad 1 is connected by bayonet socket with plastics 3, screw thread 4 is arranged on the outside of plastics 3, and other compositions are identical with the specific embodiment one with annexation.
