| Production Line: | SSAW PIPE WORKSHOP The SSAW PIPE workshop is used to produce spiral welded steel pipe. Spiral steel pipe is the strongest among welded pipes. The spiral welded pipe manufacturing process is not only one of the most efficient methods of producing steel pipes, but also offers a high degree of flexibility in the production range in terms of diameter and wall thickness. Our SSAW PIPE workshop can produce spiral pipe through the traditional 1st stage process as well as 2nd stage process (also known as off-line process). The final product is more than twice as resistant to extrusion as LSAW or ERW pipe.
LSAW PIPE WORKSHOP LSAW STEEL PIPE workshop is used for pipe diameters from 325mm to 1422mm, wall thickness from 8-50mm. In the LSAW STEEL PIPE workshop, the processing is done by cold forming of thick carbon steel plates. Among the forming processes available, Sindara Steel focuses on UOE, JCOE and HME technologies. We supply equipment for all important process steps from plate preparation to forming, welding, testing and finishing. Including not only the core machine, but also all upstream and downstream process steps required to produce large-diameter pipes. Our factory stand for medium to high production volumes of high product quality, flexible and cost-effective processes, precise dimensions and tight piping tolerances.
ERW PIPE WORKSHOP Supplying all core machines for ERW STEEL PIPE workshop, our products are renowned for their workmanship precision. The perfect combination of know-how, innovation, automation and digitalization ensures the production of high precision tubing, line pipe, casing, tubing and drill pipe as well as structural tubes with round, square and rectangular cross sections. These flexible factory lines can manufacture welded pipes with good processing quality and high-speed assembly accuracy. Covers product diameters 13.7mm to 660 mm and wall thicknesses 0.8mm-25mm.
SMLS PIPE WORKSHOP Sindara Steel Co., Ltd owns 3 sets of hot rolled seamless steel pipe production line and 2 sets of hot expanded seamless steel pipe production line and 2 sets cold rolled seamless steel pipe production line. with annual production capacity of 300,000 tons, the size range is from 73mm to 630mm. Its physical and chemical labs cab conduct various physical and chemical tests and experiments for steel pipes, and are equipped with eddy current flaw detectors,leakage fault detection and ultrasonic crack detectors etc. For high, medium and low pressure seamless steel pipes and petroleum casing pipes with a full range of inspection measures, capable to meet various standard test and inspection requirements for steel pipes.
ANTI-CORROSIVE STEEL PIPE WORKSHOP 3PE process (Three-layer Polyethylene Coating) is a widely used treatment method for steel pipe anti-corrosion, especially for buried or underwater steel pipes. 3PE is the abbreviation of three-layer polyethylene (Three-layer Polyethylene), which mainly includes three layers of structure: epoxy powder coating (FBE), adhesive layer (AD) and polyethylene layer (PE). Composition and function of 3PE process Epoxy powder coating (FBE): This is the innermost layer, directly combined with the surface of the steel pipe, providing basic anti-corrosion protection and good adhesion. Its thickness is about 30-50 microns. Located between the epoxy powder coating and the polyethylene layer, its main function is to firmly bond the two together. Its thickness is about 170-250 microns.
Polyethylene layer (PE): The outermost layer, providing good weather resistance, corrosion resistance and resistance to mechanical damage. Its thickness is generally around 2-3 mm.

| Service: | Pipe Beveling -------------------------- Beveling is the process in which we form an angle between the edge of a pipe and a plane perpendicular to the surface to a certain degree, most commonly used to prepare the ends of pipes for welding. Beveling can also be used for deburring the cut tends for safety and aesthetic reasons. Beveling can be applied to the face of any size or diameter of a pipe.
Grooving ----------------------------- Grooved mechanical piping can offer improved constructability, speedy expansion, retrofit and turnaround, and also reduce safety risks. It is a quality pipe-joining method. What is the Purpose of Grooved Pipes? Fire sprinkler system installations consist of piping. These pipes hold permanent water that is automatically released when a fire is detected. Because of the water stored in these pipes, they are under a lot of pressure. Therefore, the plumbing must be properly connected. The grooves at both ends of the two pipe ends can be connected together with a water spray pipe joint. Grooves in the pipes ensure that the pipes can be connected securely with sprinkler couplings. Cut Groove vs. Roll Groove When forming a roll groove, a pipe is cold formed to make a circular and extensive groove in the pipe. A groove is created without removing any pipe material. This is a new method compared to the cut groove, where pipe material is physically removed from the outside diameter of the pipe. Thereby, a groove is effectively cut into the pipe. Since no material is effectively removed with the roll groove, less waste remains than with a cut groove. Therefore, little cleaning work is required which subsequently speeds up the process of grooving pipes. Roll grooving can be applied on both heavy and light-walled pipes without weakening them against any corrosions. However, if the pipe wall is too thick, cut grooving the pipe will provide a more reliable groove.
Pipe Slotting ------------------------- Slots furnished in sizes from 1.900" to 20" OD. Our slot size capabilities range from 0.012” to .500” and ¼” – ½” round holes. All of our machines use a continuous flow of biodegradable coolants to maintain the pipe’s metallurgical integrity. Sindara steel can slot or round hole perforate a wide range of materials, such as carbon grades, alloys, stainless steel. We are capable of creating complete turnkey packages as easily as we can slot or perforate customer-owned materials.
Threading ------------------------------------ What are the parts of a pipe thread? The thread dimension refers to the major diameter or outside measurement. Common Pipe Thread Types
Pipe Cutting ------------------------- We can provide customized cut to size pipe for natural gas so you can jump in to your project much quickly. If you are buying sheet, tube, plate or shapes and you need simple cuts just let us know the W x L information.
3PE Anti-corrosive Pipe Coating-------------------------There are three common types of the anti-corrosion steel pipes structure in the picture Performance indexes of single-layer anti-corrosion pipe NoItem Performance Index1 Adhesion 22 Cathodic Disbonding(65℃，48h). mm 83 Cathodic Disbonding(65℃，30d) /mm 154 Bending resistance(-20℃, 2.5)No cracks the coating. There are three common types of the anti-corrosion steel pipes structure in the picture
Performance indexes of single-layer anti-corrosion pipe
Performance indexes of double-layer anti-corrosion pipe
