LSAW / SSAW Steel Pipe Supplier
If your project needs large diameter welded steel pipe, you should confirm whether LSAW or SSAW is the right route before comparing prices. Bao Steel supplies LSAW and SSAW steel pipe for piling, water transmission, oil and gas projects, structural columns, infrastructure and industrial pipe supply. Send your standard, grade, outside diameter, wall thickness, length, weld route, end finish, coating requirement, inspection document and destination so the quotation can match your actual project use.
Choose the Large Diameter Pipe Route That Fits Your Project
Before you compare large diameter pipe prices, you should confirm whether your project needs LSAW pipe, SSAW pipe, piling pipe, water transmission pipe, structural pipe or coated pipe. These routes may all be welded steel pipes, but they do not follow the same size logic, weld route, inspection requirement or packing plan.
LSAW Steel Pipe
Use this route when you need longitudinal submerged arc welded pipe for large diameter, heavy wall or project-specific pipe supply.
View LSAW Pipe →SSAW Spiral Welded Pipe
Choose this route when you need spiral welded pipe for water transmission, piling, infrastructure or long-length project pipe.
View SSAW Pipe →Large Diameter Steel Pipe
Use this route when your main concern is outside diameter, wall thickness, pipe length, transport plan and project delivery.
View Large Diameter Pipe →Steel Piling Pipe
Select this route when you need pipe piles for foundation work, port projects, bridges, marine structures or civil works.
View Piling Pipe →Water Transmission Pipe
Use this direction when your project pipe is for water transmission, drainage, irrigation or municipal pipeline supply.
View Water Pipe →Anti-Corrosion Coated Pipe
Choose this route when you need external coating, internal coating or protective treatment for buried or project pipelines.
View Coated Pipe →Large Diameter Pipe Supply Should Start from Weld Route, Diameter and Project Use
If you only compare unit price per ton, you may miss the route that actually fits your project. LSAW and SSAW pipe orders should be reviewed by outside diameter, wall thickness, pipe length, weld route, steel grade, end preparation, coating requirement, inspection documents, transport method and unloading condition.
For Large Diameter Supply
You can confirm whether LSAW or SSAW is more suitable based on OD, wall thickness, pipe length and project specification.
For Piling Projects
You can review pipe pile diameter, wall thickness, length, bevel, welding route, end use and loading plan before quotation.
For Water Projects
You can confirm pipe route, coating, internal lining, end preparation, inspection and delivery schedule for water transmission use.
For Importers and EPC Buyers
You can review project documents, pipe marking, coating details, packing method, shipping route and loading photos before shipment.
LSAW, SSAW and Large Diameter Pipe Quotation Logic
You should not treat every large welded pipe inquiry as the same pipe. Before you compare prices, confirm whether your project specifies LSAW, SSAW, API route, piling route, water transmission route or coating requirement.
| Pipe Route | What You Usually Mean | How It Relates to Project Pipe | What You Should Confirm |
|---|---|---|---|
| LSAW Steel Pipe | Longitudinal submerged arc welded pipe, often used for large diameter or heavy wall project pipe. | This route is usually selected when the project needs longitudinal weld route, controlled pipe forming and project-specific dimensions. | Confirm OD, wall thickness, grade, standard, pipe length, weld inspection, bevel, coating and delivery plan. |
| SSAW Steel Pipe | Spiral submerged arc welded pipe for water projects, piling, infrastructure and large diameter supply. | This route can support many large diameter project needs, especially when spiral welded pipe is allowed by specification. | Confirm spiral weld route acceptance, size, wall thickness, coating, end finish and inspection requirement. |
| API 5L Pipe Route | Line pipe route for oil, gas, water or pipeline-related projects. | API 5L can involve different manufacturing routes. You should confirm whether LSAW, SSAW, ERW or seamless route is required. | Confirm PSL level, grade, OD, wall thickness, pipe route, bevel, marking, coating and inspection requirement. |
| Steel Piling Pipe | Pipe piles for foundation, bridge, marine, port or civil engineering projects. | Piling pipe is often selected by structural load, diameter, wall thickness, pipe length and project installation method. | Confirm pile diameter, length, wall thickness, end preparation, coating, weld route and delivery method. |
| Water Transmission Pipe | Large welded pipe used for water transmission, drainage, irrigation or municipal pipeline work. | This route may need coating or lining requirements in addition to pipe size and steel grade. | Confirm water medium, pressure condition, coating, internal lining, pipe ends, inspection and shipment plan. |
| Anti-Corrosion Coated Pipe | Steel pipe with external coating, internal coating or protective treatment for project pipelines. | Coating route should be confirmed before quotation because it affects processing, packing, delivery time and inspection. | Confirm coating type, thickness, standard, pipe size, handling method and storage condition. |
| ERW Carbon Steel Pipe | Electric resistance welded pipe for general pipe, line pipe or smaller welded pipe routes. | ERW may be suitable for some welded pipe orders, but it is not the same as LSAW or SSAW large diameter route. | Do not replace LSAW or SSAW with ERW unless the size and project specification allow it. |
| Seamless Carbon Steel Pipe | Pipe without welded seam for pressure, mechanical or high-temperature applications. | Seamless pipe is a different route and is usually not the main option for large diameter project pipe. | Confirm whether the project requires seamless construction before comparing welded pipe options. |
