ERW Steel Pipe Galvanized Pipe ASTM A53 ERW EMT Oil&Gas Drill Pipe BS 1387 4 Inch 6 Inch Diameter Gi Galvanized Pipe Tube for Fence Posts and Greenhouse

Product Description

Galvanized steel pipe is a type of steel pipe that has a layer of metal zinc plated on its surface. Its main functions are to prevent rust and corrosion, and to extend the service life. It is a very commonly used pipe material in engineering, water supply and drainage, gas, and wiring projects.

Specification

Galvanized steel pipe tube
Hot-dip galvanized pipes are steel pipes coated with a layer of zinc through a hot-dip process. This enhances their resistance to corrosion and rust, making them ideal for outdoor and industrial applications. They are widely used in construction, water supply, plumbing,and for conveying gas and oil in various industries.
Galvanized square pipe is a welded steel pipe with a hot-dip or electro-galvanized layer on the surface. Galvanizing can increase the corrosion resistance of steel pipes and prolong their service life. Galvanized pipes are widely used. In addition to being used as pipeline pipes for general low-pressure fluids such as water, gas, and oil, they are also used as oil well pipes and oil pipelines in the petroleum industry, especially offshore oil fields, and oil heaters and condensation pipes for chemical coking equipment. Pipes for coolers, coal distillation washing oil exchangers, trestle piles, and support pipes for mine tunnels, etc.
RHS and SHS tube are a welded structural grade tubing,depending on its size and wall thickness. Either grade is ideal for all structural applications, general fabrication, manufacturing and repairs.
Square hollow section is widely used in industrial maintenance, agricultural implements, transportation equipment, truck beds,trailers, frames, etc. Its box-shape configuration allows for much greater strength and rigidity compared to angles or channels.
The raw materials come from well-known large factories
The ends of steel pipe are clean and neat without burrs
High precision, tolerance range is small
The performance of products meets various standards,such as ASTM,GB,JS.

Product Details

1. Hot-dip galvanized steel pipe (mainstream, durable)
The steel pipe is immersed in high-temperature zinc liquid, resulting in a thick and strong zinc layer with good adhesion and low peeling tendency.
It has excellent corrosion resistance and is suitable for outdoor, underground, and humid environments.
The surface is a bright silver-white color or with slight patterns.

2. Electro-galvanized steel pipe (cold galvanization)
Electroplating process, with a thin and uniform zinc layer.
Low cost, but rust prevention is average, mostly used in indoor and dry environments.
It is now less used in important pipelines in engineering projects.

Common specifications

Bore diameter: DN15, DN20, DN25, DN32, DN40, DN50, DN65, DN80, DN100...

Wall thickness: Mainly 2.0mm - 4.5mm

Length: Generally 6 meters / piece

1.Customization of specifications and dimensions: We can produce according to different outer diameters, wall thicknesses, lengths and materials. Processing and cutting can be done based on drawings or engineering requirements. 

2.Surface processing customization: 
Offer options of hot-dip galvanizing or electro-galvanizing, and can customize the zinc layer thickness, coating weight, passivation treatment, painting or anti-corrosion coating and other surface treatment schemes. 

3.Advanced processing services: Provide secondary processing such as pipe cutting, threading, hole drilling, pipe bending, welding, marking and dedicated packaging.

Product Application

Building fire protection pipelines (most common)
Freshwater supply, outdoor pipeline network of the community
Gas transmission pipelines
Electrical cable protection sleeves (conduit pipes)
Steel structures, scaffolding, guardrails
Industrial fluid transportation, mild corrosive environment in the chemical industry
