Seamless Steel Conical Pipe

Seamless Steel Conical Pipe

1. Introduction of Conical Pipe

Conical pipe is a typical pipe fitting in ship piping system, which is the filter element between pipes of different diameters in ship piping system.

Conical pipe is divided into conical welded pipe and conical seamless pipe, that is, welded conical pipe and seamless conical steel pipe.

Seamless conical tube is relatively rare, the production needs special equipment, advanced production technology, can ensure the thickness of the tube body uniform size, tube outside the round to meet the design requirements.

Raw material for seamless steel pipe, the main material to carbon steel, alloy steel and stainless steel can also be.

2. KEYA mainly supplies all kinds of seamless and welded tapered steel tubes.

1) Seamless tapered steel pipe

Due to the limitation of the production process, the seamless conical steel tube has the minimum outer diameter of 60mm, the maximum outer diameter of 450mm, the thickness of 6mm-40mm, the maximum length of 8 meters, the material of 20#, 304,316L, Q345B, 12Cr5Mo, etc.

Seamless tapered steel tubes are mostly custom-made. Carbon steel is widely used in conical pipe design and production. Seamless carbon steel 20# is the main material. 20# steel has low harden ability, good plasticity, toughness and weld ability, and better toughness after hot rolling or normalizing.

Usage

Seamless conical steel pipe is mainly used for large diameter steel pipe and small diameter steel pipe docking, fluid transport.

Conical boiler drains for power plants

Seamless tapered steel tube for oxygen lance for steel making furnace

Lightning rod column of nuclear power plant

Stations, airports, car showrooms and other steel structure of the place of the column

Conicity 

The taper is used to calculate the size of the cone, and the slope is also called slope, which is used to calculate the size of the inclined plane. The length of the cone is divided by the height of the decreasing head, and the obtained number is the value of the tangent function, and then the value of the taper can be obtained by looking up the tangent function table.

2) Welded conical pipe

There are more welded pipes in the market. Welded pipe refers to the steel pipe made of steel plate or strip after being welded by crimping. All kinds of welded cones can be customized. 

30X60-500X900 wall thickness of 3mm-25mm

Material: Q235B, Q345B/D, 20#, stainless steel 

3. FAQ

1) What information needed if we want to customize the conical steel pipe?

The OD of big end and small end, wall thickness, length, material, qty.

2) Will the welded tapered pipe straight?

The welded tapered pipe will be straightened after welding.
