Anti-static pipe clamp

Abstract

The invention discloses an anti-static pipe clamp, comprising of a lining, an U-type bolt, a base plate, a nut and a cushion block. The U-type bolt has a structure of double threads. The base plate is a panel veneer which is symmetrically bended in the length direction and is equipped with through holes on the extended edges of both ends. The middle of the base plate is like a trilateral groove and the diameter of the circle internally tangent to the midpoints of the groove's three sides is equal to the outer diameter of a cargo pipe line to be clamped in length. The lining and the cushion block is made of insulation materials. The lining is U-type and the outer wall of the lining is equipped with a semicircle groove matched with the inner wall of the U-type bolt. The cushion block is a rectangle sheet. The installed lining and cushion block form an insulation structure between the pipe clamp and the cargo pipe line to be clamped. Even if an axial displacement of the cargo pipe line happens, no static electricity is generated. The anti-static pipe clamp has a simple structure and is reliable in connection and is safe to use, and can match cargo pipe lines with various pipe sizes.

Description

technical field [0001] The invention relates to a pipeline accessory, in particular to an antistatic pipe clip used for locking cargo oil pipes on a chemical ship. Background technique [0002] The cargo carried by chemical tankers is usually liquid or gaseous items, and most of these items are inflammable and explosive. Chemical tankers store items in separate compartments, and cargo oil pipes are the main passages for loading and unloading cargo in each tank. For the convenience of loading and unloading, the cargo oil pipes connecting each tank are arranged on the deck. A ship is a structure floating on the water, and it is common for the hull to sway during navigation. The turbulence can easily cause the cargo oil pipeline to shake on the deck. Hidden dangers, especially when the cargo is flammable and explosive, it is more harmful. In the prior art, in order to prevent the cargo oil pipeline from shaking when the hull is pitching, the cargo oil pipeline is locked at th...

AI Technical Summary

Problems solved by technology

However, the prior art does not solve the electrostatic problem caused by the axial displacement of the cargo oil pipeline

When the ambient temperature or the temperature of the transport medium changes, the cargo oil pipe will inevitably have an axial displacement relative to the pipe clamp, and the static electricity generated by this displacement also poses a safety hazard to chemical tankers
