Introduction to Spiral Welded Steel Pipes
Organism
It is also known as the solenoid or the supercoil. The outer diameter of the solenoid is approximately 30 nanometers, while its inner diameter is about 10 nanometers, with a pitch of roughly 11 nanometers between successive turns. Each turn of the solenoid is composed of six nucleosomes, and the H1 histone protein resides on the inner surface of the solenoid lumen, playing a crucial role in maintaining the solenoid’s structural integrity. The 10-nanometer fiber, which consists of nucleosomes, further coils into a 30-nanometer‑diameter fiber, thereby compressing the DNA length by an additional factor of six.
Industrial piping
Spiral welded steel pipes are primarily used for the transmission of oil and natural gas, with their dimensions specified as outer diameter × wall thickness. These pipes are available in single-sided and double-sided welded configurations, and they must meet prescribed requirements for hydrostatic testing, weld tensile strength, and cold‑bending performance.
The spiral pipe manufacturer’s flagship products include spiral‑seam double‑sided submerged‑arc welded steel pipes with diameters ranging from 219 to 3,420 mm and wall thicknesses from 6 to 26 mm, as well as large‑diameter thick‑walled straight‑seam double‑sided submerged‑arc welded steel pipes—whose wall thickness can reach up to 70 mm. With an annual production capacity of 80,000 tons, these products are widely used in pipeline systems for natural gas, petroleum, chemical processing, power generation, district heating, water supply and drainage, sugar refining, papermaking, and other industries, as well as in piling applications and steel support structures for subways. To ensure superior weld quality, the plant has equipped its entire production line with state-of-the-art Lincoln welding equipment from the United States, along with complementary nondestructive testing devices, including portable X‑ray inspection for full‑weld‑seam examination, ultrasonic testing, and hydrostatic pressure testing. A comprehensive system of quality control points, inspection checkpoints, and a complete process flow has been established, supported by advanced physicochemical testing facilities tailored to each product. As a result, product quality—including appearance, geometric dimensions, and root‑pass weld integrity—fully complies with the industry standard SY/T 5037‑2012 issued by the Ministry of Petroleum Industry. Guided by the principle of “excellent quality, customer first,” the company remains committed to providing honest, reliable service to every customer.
Spiral steel pipes are used in a variety of industries and are manufactured using specific processing and fabrication techniques, enabling them to deliver significant performance and value in construction projects. A spiral steel pipe is a type of pipe whose weld seam is arranged in a helical pattern relative to the pipe’s longitudinal axis. It is primarily employed for pipeline transportation, pile foundations, and certain structural applications. As the pressure ratings of spiral steel pipelines continue to rise and operating conditions grow increasingly demanding, it is essential to maximize the service life of these pipelines.
