Abstract

A seawater-proof pipe clamp is used in the fields of ships sailing at sea, oil and gas drilling platforms, oil refineries and the like on offshore and offshore islands. The use of seawater pipelines has a common corrosion problem, and the corrosion is divided into two types, namely pitting corrosion and crevice corrosion. The corrosion point or surface is generated by the motion friction between the pipeline and the pipe clamp or other hard objects, the friction is generated by the dynamic environment of the sea bottom and the sea water, the consequences caused by corrosion damage of the pipeline are serious due to earthquakes, ocean currents and the like, the economic loss and the difficulty of fault finding in maintenance are high, and the problem is a general problem proved by research and cases. The seawater-proof pipe clamp can solve the problems and adopts the technical scheme that an upper pipe clamp body (3) is designed below a cover plate (2), and an upper hole groove (3-1) is formed in the middle of a lower opening surface; the lower pipe clamp body (4) is designed below the upper pipe clamp body (3), and a lower hole groove (4-1) is arranged in the middle of the upper opening surface.

Description

Seawater-proof pipe clamp

Technical Field

The utility model relates to a "prevent sea water pipe clamp", it uses in the pipeline engineering field of ocean.

Background

Ships sailing at sea, oil and gas drilling platforms, oil refineries and oil refineries on offshore and near-shore islands all use stainless steel as a typical steel pipe material, but all have a common corrosion problem, namely corrosion is divided into two types, namely pitting corrosion and crevice corrosion. The corrosion point or surface is generated by the motion friction between the pipeline and the pipe clamp or other hard objects, the friction is generated by the dynamic environment of the sea bottom and the sea water, the consequences caused by corrosion damage of the pipeline are serious due to earthquakes, ocean currents and the like, the economic loss and the difficulty of fault finding in maintenance are high, and the problem is a general problem proved by research and cases.

Disclosure of Invention

For solving the above difficult problem, the utility model provides a technical problem adopts technical scheme, characterized by: the upper pipe clamp body 3 is designed below the cover plate 2, and an upper hole groove 3-1 is arranged in the middle of the lower opening surface; the lower pipe clamp body 4 is designed below the upper pipe clamp body 3, a lower hole groove 4-1 is formed in the middle of the upper opening face, the bottom plate 5 is designed below the lower pipe clamp body 4, the rubber strips 6 are respectively fixed in the upper hole groove 3-1 and the lower hole groove 4-1, and the bolt 1 penetrates through the cover plate 2, the upper pipe clamp body 3 and the lower pipe clamp body 4 to be connected with the bottom plate 5.

The working principle is as follows: the common pipe clamp is used on the land, two semicircular holes are formed in two sides of the contact surface part of the upper pipe clamp body and the lower pipe clamp body, and a circular pipeline with a cable penetrating into the interior is clamped, pressed and fixed up and down, so that the pipeline is stable, and the cable in the interior is safe; the seawater-proof pipe clamp is used in seawater or seabed, two sides of the contact surface part of the upper pipe clamp body and the lower pipe clamp body are provided with two half hexagonal holes, the rubber strip 6 is also arranged in the holes, after the circular cable pipeline penetrates into the holes, the upper pipe clamp body and the lower pipe clamp body clamp the pipeline firmly through the rubber strip 6, because the rubber strip 6 is a soft body and is completely attached to the surface layer contact surface of the circular pipeline body, the rubber strip cannot invade seawater and cannot be embedded into sand stones when the pipeline body is slightly shaken under the action of external force, thus effectively avoiding the damage of internal circuits caused by the friction of the sand stones, salt grains, impurities and the like on the surface of the cable pipeline due to the vibration caused by seabed ocean current, volcano, tide, seabed organisms and the like, and the gaps are remained around the circular cable pipeline clamped by the hexagonal holes, so that the flowing impurities can smoothly pass through the gaps along with the seawater, the pipe clamp is not detained around the pipe clamp, and the influence on the pipeline is avoided. The rubber strip 6 not only has the effects of being flexibly attached to the surface of the pipeline, not generating friction with the surface of the pipeline, but also has the effect of damping, avoids equipment damage or economic loss, and is also the core technology of the seawater pipe clamp.

The utility model has the advantages that: after the arc-shaped hole is changed into the hexagonal hole on the basis of the existing pipe clamp and the rubber strip 6 is added, the cable pipeline is protected when being used on the seabed, and the beneficial effects of the cable pipeline are obvious.
