Many industries depend on the stainless steel welded pipe for critical tasks. Manufacturers carefully join flat steel to create these strong, tubular products. These essential components support infrastructure and production around the world.
Stainless steel welded pipe is made using stainless steel, a metal known for resisting rust. It starts as a flat piece of metal that gets rolled into a tube shape. The seam where the edges meet is then securely welded shut.

Company Description
Baosteel Group Corporation, based in Shanghai, China, got its start way back in 1978. The original name was Baoshan Iron & Steel (Group) Corporation. It grew pretty fast, becoming a major world steel company. The whole idea came about during China’s economic changes – leader Deng Xiaoping really pushed for a large steel operation, seeing the first factory as a key project.
Later on, in 1998, the company expanded again. It merged with two others, Shanghai Metallurgical Holding Group Corporation and Shanghai Meishan Group. That combination formed the Shanghai Baosteel Group Corporation. At the time, it was China’s biggest steel maker. Then, a specific part, Baoshan Iron & Steel Co., Ltd., was set up in early 2000; it started trading on the Shanghai Stock Exchange later that year.
The company’s main offices? They’re in the Baosteel Tower in Pudong, Shanghai. It has definitely seen some big changes over time. Like in 2016, Baosteel Group joined up with Wuhan Iron and Steel Corporation (another state-owned firm). This move created China Baowu Steel Group Corp., Ltd., or just Baowu, usually. And Baowu is currently the world’s biggest steel producer.
Making stainless steel welded pipes – most of that happens at the Ningbo Baoxin Stainless Steel Co., Ltd. facility. This factory sits in the Ningbo Economic and Technological Development Zone. It’s a big place, 650,000 square meters, making about 10,000 tons of cold-rolled stainless steel welded pipe every year. Being right near the Ningbo Beilun Port is pretty convenient for shipping materials in and pipes out.
The stainless steel welded pipes meet tough international standards. People know them for quality and being reliable. Lots of different industries use these pipes – you’ll see them in petrochemical plants, food processing, drug manufacturing, water treatment, and building projects. Stainless steel resists rust much better than regular carbon steel, right? That makes these pipes good for demanding spots where standard pipes would just wear out.
Jianglin Steel
Year Founded: 2003
Main Products
- Stainless steel welded pipes/tubes
- Stainless steel coils, sheets, and plates
- Precision stainless steel strips
- Stainless steel form products
Company Description
Jianglin Steel, officially Tianjin Jianglin Technology Development Co., Ltd., is located in Wuqing District, Tianjin, China, specifically in Yuanjiabao Village, Chagugang. Chairman Wang Junjiang started the company back in June 2003. The initial investment was quite large, around 500 million RMB.
The factory itself covers about 21,000 square meters. That space allows Jianglin Steel to produce a lot of material. Yearly production capacity reaches about 700,000 tons.
Being close to Tianjin Port, only 40 minutes away, is a big help for the company. This location makes it much easier to handle international trade and ship products globally. It’s a useful spot for business.
Over the past twenty years or so, Jianglin has grown quite a bit. It started as just one manufacturing place but has become a larger group. Now, the company has two main production centers, one for stainless steel and another for aluminum.
Making stainless steel welded pipes is a really important part of what Jianglin does. They offer two main kinds. Industrial pipes are built tough for jobs needing strength and something that won’t easily corrode. Then there are decorative tubes, which usually have thinner walls (under 1.0mm) and are used mostly for looks in buildings or design projects.
You can get these welded stainless steel pipes in various sizes. The outside diameter goes from 20mm all the way up to 1000mm. Wall thickness ranges from 0.5mm to 8.0mm. All the pipes meet international standards like ASTM A554, A269, and A312, meaning they’re good for use pretty much anywhere in the world.

This way of making pipes is efficient and helps keep the quality steady.
Many industries use the welded pipes from Wujin Stainless. The energy sector relies on them quite a bit, and so does the field of advanced equipment production. You’ll find the stainless steel welded pipes in places like oil processing, chemical plants, natural gas facilities, power generation equipment, and machine building. These are places needing materials that resist rust and last a long time.
What helps Wujin Stainless stand out is the big selection of sizes it offers. Its welded pipes come in lots of different diameters—from small to large—and various wall thicknesses too. This variety means the company can supply pipes for many different customer needs. It’s become a go-to supplier both inside China and in other countries around the world because of this flexibility.
