Stainless steel pipe is mainly used for three purposes:
1. Stainless steel decorative pipe
In fact, it is a stainless steel pipe used for decoration, which is mainly widely used in stainless steel anti-theft windows, stair guardrails, stair handrails, etc.
2. Stainless steel industrial pipe
It is divided into seamless pipe and welded pipe.
Scope of application: due to the thin stainless steel welded pipe and good surface treatment effect, it is mainly used for architectural decoration products, civil decorative art stainless steel products, etc. The stainless steel industrial pipe has thick wall, uneven surface and strong bearing capacity. It is mainly used to make large size, high strength, high toughness, mechanical systems and other products.
3. Stainless steel product pipe
Stainless steel product pipe refers to the stainless steel pipe specially customized by the stainless steel pipe manufacturer because the ordinary stainless steel decorative pipe does not meet its use requirements.
Galvanized pipe Hot diped ， Electroplating diped
Hot-dip galvanized steel pipes are widely used in the manufacturing industries of construction, machinery, coal mining, chemical industry, electric power, railway vehicles, automobile industry, highways, bridges, containers, sports facilities, agricultural machinery, petroleum machinery, prospecting machinery, shed construction, etc.
316L stainless steel pipe is commonly used in pulp and paper making equipment, heat exchanger, dyeing equipment, film processing equipment, pipes, materials used for the exterior of buildings in coastal areas, as well as watch chains and case of advanced watches.
Structural Steel Pipe. A wide range of applications rely on structural steel pipe for strength and stability. Gnee steel supply welded and seamless pipe for structural applications to customers in all industries. As a leading steel pipe supplier, Gnee steel offers a large inventory of pipe and tubing sizes from 1/8” NPS to 48” NPS.
API 5L X80 carbon welded steel pipe
API 5L X80 Pipe is a standardization for pipeline transportation systems within the rock oil, gas, water, and fossil fuel industries. API 5L-X80 steel is used in polar regions, wherever high toughness at low temperatures is needed.Product introduction

Hot dip galvanized pipe is to make molten metal react with iron substrate to produce alloy layer, so that the substrate and coating can be combined. Hot galvanizing refers to pickling the steel pipe first. In order to remove iron oxide on the steel pipe surface, after pickling, the steel pipe is cleaned in ammonium chloride or zinc chloride aqueous solution or mixed ammonium chloride and zinc chloride aqueous solution tank, and then sent to the hot dip tank. Hot dip galvanizing has the advantages of even coating, strong adhesion and long service life.
A283 carbon steel pipe is widely used in buildings and engineering structures. It is used for making steel bars or building workshop frames, high-voltage transmission towers, bridges, vehicles, boilers, containers, ships, etc., and is also widely used as mechanical parts with low performance requirements.
904L stainless steel pipe (super austenitic stainless steel) is a high alloyed austenitic stainless steel with very low carbon content. It has good corrosion resistance in dilute sulfuric acid and is specially designed for environments with severe corrosion conditions. It has high chromium content and sufficient nickel content. The addition of copper makes it have strong acid resistance, especially high resistance to chloride interstitial corrosion and stress corrosion cracking. It is not easy to appear corrosion spots and cracks. Its pitting resistance is slightly better than that of other steels. It has good processability and weldability, and can be used for pressure vessels.
