MS PipesStraight Seam Tube Steel Plc Control Steel Pipe Production Line

Machine Introduction

The technical process of 300 square pipe equipment is generally: material preparation, uncoiling, straightening, butt welding, milling, forming, welding, deburring, weld annealing, sizing, defect detection, sizing cutting, testing, straightening, hydraulic test, pipe end finishing and other main processes. These processes fully ensure the quality of welded pipe products. The external dimensions of the products, such as pipe diameter, wall thickness, ovality, bending, tube end verticality, etc., have been tested by hydrostatic test, acid etching test, nondestructive test, and other tests in chemical aspects. These are the basis to ensure that the products produced by the welded pipe unit meet the standards.

Machine Characteristics

Welded steel pipe, also known as welded pipe, is made of steel plate or steel strip after crimping welded steel pipe. Welded steel pipe has the advantages of the simple production process, high production efficiency, many varieties and specifications, and less equipment investment, but its general strength is lower than that of seamless steel pipe.

Theory

Steel tube production line to certain specifications of the galvanized steel belt feeding machine, curled up into a tube by forming roller steel billet, and then use the high frequency of proximity effect and skin effect make the tube side quickly heated to welding temperature, and under the squeezing roller extrusion complete welding, and then through the zinc patching machine is to burn high-frequency weld position to catch up on the zinc layer, then through cooling, Galvanized pipe to the required specification by sizing and rough straightening. Because the antirust cost of galvanized pipe is lower than the cost of other coatings; So the use is very wide, and durable general use of more than 20 years is no problem.

Application

Galvanized welded steel pipe for low-pressure fluid transportation (GB/T3091-2008) is also known as galvanized welded steel pipe, commonly known as a white pipe. It is used for conveying water, gas, air oil, heating steam, warm water, and other general low-pressure fluid or other purposes of hot-dip galvanized welded steel pipe (furnace welding or electric welding). The wall thickness of steel pipe is divided into ordinary galvanized steel pipe and thickened galvanized steel pipe. Nozzle end form is divided into galvanized steel pipe without thread and galvanized steel pipe with thread. The specification of steel pipe is expressed in nominal caliber (mm), which is an approximation of the inside diameter. It is customary to use inches, such as 1/2, 3/4, 1, 2, etc.

FAQ

Q: Are you a manufacturer?
A: Yes, we are a manufacturer. We have 4 factories ( Machining, Assembling, Heat treatment, and Moulding ). We also have our own R&D department. Welcome to visit us.
Q: What kind of payment term do you do?
A: We do T/T.
Q: What info do you need before giving me the price and proposal?
A: Since we design individual machines based on our customer's requirements, we need your desired products' basic dimensions, including all the pipe diameter(or tube length), thickness range, usage, raw material steel grade, coil weight, and degree of automation.
Q: What should I do if I just start a new business?
A: Contact us immediately, we provide a free consultant for pre-sales service. Also, we can help you solve the raw material (steel coil) purchase, worker training, international market price, and more.
Q: How do you do QA?
A: We have a special team to do strict QA, this is one of our strengths:
(1)Every gearbox will be tested for 8 hours with oil inside to guarantee there is no leak.

(2)Every shaft will be inspected for centering jumpiness.
(3)Every roller will be checked to make sure it's in the range of tolerance critical parts will be inspected for all dimensions.
Q: Why I should choose you? what are the differences between you and other Chinese suppliers?
A: We are concentrating on pipe-making machines for more than 20 years. We have constructed many steady trading partners in Asia, Africa, the middle east, Europe, and South America throughout the years. Our innovative designed production line and every single unit of the production line are economical and practical.
