Benefits of SSAW Steel Pipe

High structural integrity
Ssaw (spiral submerged arc welded) steel pipes have high structural strength and are ideal for applications that require robust performance under high pressure and heavy loads.

Wide range of sizes
The spiral welding process can accommodate a wide range of pipe diameters and wall thicknesses to meet a variety of industrial needs.

Cost efficiency
The continuous welding process used in ssaw pipe production is efficient and reduces material waste, resulting in cost-effective manufacturing.

Excellent weld quality
The submerged arc welding technology ensures deep penetration and high-quality welds, improving the mechanical properties of the pipe.

Uniform stress distribution
The spiral seam design provides a uniform weld, thereby evenly distributing stress and improving the overall integrity of the pipe.

Enhanced corrosion and fatigue resistance
Ssaw pipes can be coated for improved corrosion resistance, and the spiral weld pattern provides excellent fatigue resistance.

Wide range of applications
These pipes are versatile and can be used in both onshore and offshore environments.

Applications of SSAW Steel Pipe

Oil and gas pipes
Due to their strength and durability, ssaw pipes are often used to transport oil, gas, and other fluids over long distances.

They are ideal for water supply networks, sewage systems, and drainage projects.

Construction and structural uses
Ssaw pipes are used in the construction of bridges, high-rise buildings, and other infrastructure projects that require large-diameter, high-strength pipes.

Foundation piling
These pipes are used as piling pipes in construction to provide foundation support and stability.

Industrial uses
Ssaw pipes can be found in various industrial applications, including chemical processing, power plants, and mechanical engineering.

Offshore engineering
Ssaw pipes are ideal for offshore drilling and marine projects due to their corrosion resistance and ability to withstand harsh conditions.

Agricultural irrigation systems
These pipes are used in irrigation systems to ensure efficient distribution of water to farmland.

You Can Learn About Our Spiral Saw Steel Pipe Surface Treatment Technology

Manual rust removal:

Eliminate scale and casting sand from the surface of pipes, equipment, and containers using a scraper and file. Subsequently, employ a wire brush to clear away any floating rust on the surface. Follow this by sanding with sandpaper and, finally, wipe the surface with a cotton silk net.

Mechanical rust removal:

Begin by scraping or filing off scale and casting sand from the pipe's surface. Then, with one person positioned in front and another behind the descaling machine, repeatedly descale the pipe until the true metal color is revealed. Before applying oil, use cotton silk to wipe away any remaining surface ash.

Anti-corrosion brush oil:

Typically, pipelines, equipment, and container valves undergo anti-corrosion treatment and oiling as per design requirements. In the absence of specific design criteria, adhere to the following guidelines: A. For surface-mounted pipelines, equipment, and containers, initiate the process by applying one layer of anti-rust paint, followed by two topcoats before handover. If heat preservation and anti-condensation are stipulated, two coats of anti-rust paint should be applied. B. Concealed pipelines, equipment, and containers should be treated with two coats of anti-rust paint. Ensure the second coat is applied only after the first one has completely dried, maintaining the appropriate consistency of the anti-rust paint.

Our Production Process for Spiral Sawn Steel Pipes

(1) Raw materials, i.E. Strip, welding wire and flux. They must be strictly tested before being put into physical and chemical testing.

(2) The strip is butted head and tail by single-wire or double-wire submerged arc welding, and automatic submerged arc welding is used when the steel is rolled.

(3) Before forming, the strip is leveled, cut, trimmed, planed, surface cleaned and conveyed to the bending process.

(4) Electric contactors are used on both sides of the conveyor to control the pressure of the pressurized cylinder to ensure the smooth conveying of the strip.

(5) Internal or external control roller forming is adopted.

(6) The weld gap control device ensures that the weld gap meets the welding requirements. The diameter, volume and misalignment of the weld gap are strictly controlled.

(7) Both welding and brazing are performed by single-wire or double-wire submerged arc welding with the american lincoln welding machine, which can obtain stable welding specifications.

(8) After welding, the weld line is continuously inspected for damage by ultrasonic wave to ensure that the non-destructive testing coverage of the spiral weld is 100%. If there are defects, the alarm will be automatically sounded and the mark will be sprayed. The production workers will adjust the process parameters accordingly to eliminate the defects.

(9) Use an air plasma cutting machine to cut a single pipe.

(10) After cutting into a single steel pipe, each batch of steel should be subject to a strict inspection system to check the mechanical properties, chemical composition, fusion status, steel surface quality, etc. Of the weld and undergo non-destructive testing and other process inspections to ensure that the steel pipe is qualified before it can be officially put into production.

(11) For areas with continuous ultrasonic flaw detection marks on the weld, manual ultrasonic and x-ray re-inspection will be carried out. If there are defects, they will be repaired and then destructive tests will be carried out until it is confirmed that the defects have been eliminated.

(12) The butt welds of the steel pipe and the intersections of the spiral welds and d-type joints are all inspected by x-ray television or film.

(13) Each steel pipe is tested for radial sealing under water pressure test pressure. The test pressure and pressure time of the steel pipe are strictly controlled by a microcomputer test device. The test parameters are automatically printed and recorded.

(14)Process the pipe ends to make them vertical and the blunt edge grooves accurately controlled.

Coating, Marking and Packaging

After the production of welded steel pipes is completed, tianjin xingxintong metal technology co., ltd. Performs surface coating on carbon steel pipes according to customer requirements to prevent corrosion. Standard coatings are black paint, varnish and anti-rust oil, which can play a temporary anti-rust role during transportation. If fbe, pe or pp coating is required, the pipe will be transported and finished in the coating machine.

Tianjin xingxintong metal technology co., ltd. Affixes a barcode on the inner wall of each steel pipe, and the barcode on the pipe end is unique. The barcode is equivalent to the id card of each unit under the steel pipe, recording the furnace number, pipe number, steel grade and production information of each pipe. After completing the coating process, the production worker scans the barcode to obtain the corresponding product information, and marks the pipe according to the standards and contract requirements to ensure the traceability of the product.

Generally speaking, the packaging of the product plays a vital role in the protection of the product during transportation, so the company also pays great attention to this process. According to the size, coating and other processing information of the steel pipe, the company usually uses end caps, pvc packaging, nylon slings, galvanized belts, fumigated wood and other materials to protect the steel pipe. At the same time, because some of our customers require more sturdy, stable and easy-to-unload packaging solutions, engineers can generate customized packaging solutions.

Before delivery to customers, inspectors will recheck the appearance, packaging, marking labels, labels and other specifications of the black steel pipe to ensure that customers will not receive any defective products. After passing the inspection, the quality assurance department of tianjin xingxintong metal technology co., ltd. Issues a factory test certificate based on each batch of shipped steel pipes
