Non Metallic Coatings Q235 Q345 L175 Welded Steel Pipe

Welded Pipes Finishing
The finishing of welded pipes depends on customer requirements and applications. These include threaded and coupled ends for use in long fluid transportation lines, threaded end without coupling for diverse diameter lines, Plain End or Cut Square for the general purposes. Pipes with pre-grooved or bevelled end are supplied for structural applications.
A different metallic coating like galvanising, lead lining, aluminising and claddings are also used for corrosion protection during applications. Non-metallic coatings such as oiling, paints, plastic coating, coal tar etc are also used for protection during storage and transportation. End finishing and coatings add significant costs to the welded pipes.

Designations and Specifications
ASTM A53 and API-5L are commonly used to define general specifications of welded pipes. ASTM B36.10 standard is used to define sizes and dimensions of pipes and tubes. While some of the industries have their own norms and custom sizes.
In North America, designations used to define pipes sizes are known as Nominal Pipe Size (NPS) and Schedule Number (Sch.). NPS defines the internal diameter of pipes and Sch. refers to the range of wall thickness.
In European standards, Nominal Bore (NB) is used to represent the internal diameter in mm and OD represents the outer diameters of pipes and tubes. ASTM/ANSI standard weights are usually expressed in Kg/m or lb/ft.

The following length standards are used in the market and are vital for the pipeline project designs.
1. Single random length (SRL) ranges between 18 – 25 feet plain end or 18 – 22 feet threaded and coupled pipes.
2. Double random length (DRL) ranges between 38-40 feet.
3. Longer than double random is more than 38 – 40 feet in length.
4. Cut Lengths are produced in fixed lengths within +/- 1/8 inch, while some are produced up to 80 feet long.

Hebei Huayang Steel Pipe Company Ltd. is the largest ERW and LSAW steel pipe manufacturer in Northern China. Established in 2005, we have a modern factory covering an area of 666,000 square meters, with over 700 employees and a fixed asset of 200 million USD, annual output capacity is up to 1,000,000 Tons.

We are located in Cangzhou city, Hebei province, a large steel production base in Northern China. Huayang is near to the raw material steel mill, such as Hebei Zhongtie Equipment Company, Shandong Iron and Steel Co., Ltd, Shougang Group, Jinxi Group, which reduce the material cost. At the same time, Huayang is 210 kilometers from Beijing, 150 kilometers from Tianjin City, 160 kilometers from Xingang port, with convenient transportation, which is convenient for customer’s visit and reduce the transportation cost. With lower material cost control, we can offer more competitive price and significant profit for our customers.

Huayang use advanced imported production equipment such as German once-through rolling machines, British CT METORI digital controllers, one φ114.3mm-φ168.3mm ERW steel production line, three φ219mm-φ426mm ERW steel pipe production line, one φ426mm-φ660mm ERW steel pipe production line, one JCOE production lines for LSAW pipe, size range from 16” to 56” (406.4mm-1422.4mm), wall thickness: 9.53mm-50mm. In 2018, we build a new advanced RBE production line for LSAW pipe, size range from 16” to 56” (406.4mm-1422.4mm), wall thickness: 9.53mm-30mm.

Twenty φ245mm-φ820mm thermal expansion pipe production lines, we have our own high-tech physics and chemistry labs where we can conduct our own tests such as physical properties and chemical composition test, and as well, UT, hydraulic test, X-ray and other test equipment is available, which can meet all related standards and inspection requirements.

In order to provide One-Stop service for customers with superior products from qualified supplier, Huayang set up branch company, Cangzhou Wingo International Trading Co., Ltd in 2013, to help customers purchase different products, such as seamless steel pipes, SSAW steel pipes, Galvanized pipes, Anti-corrosion pipes, pipe fittings and flanges etc.

Huayang steel pipes are used as the construction material and the pipelines for oil, gas, water, steam, and other middle & low hydraulic pressure fluids. Huayang’s products are sold nationwide and mainly exported to Southeast Asia, Middle East, South America, Africa, North America and Europe. Our company has consistently aimed to provide our customers with high quality, affordable industrial pipes. “Huayang” brand steel pipe has gained praises and high reputation from all of the world.
