Hydraulic High Wall Thickness Tube Pipe Grooving Groove Machine

SDD HDD ID Heavy Duty Pipe Beveling Machine

Overview
Co-Pack heavy duty pipe beveling machine is a portable ID mounted machine, which adopts automatically feed mechanism, and the bevel angel can be adjustable. The machine can be used for beveling thick pipe and prepare for welding flange faces. With the special structure designing, the tool stroke can be fine-turning. Auto-feeding and Manual -feeding can be easily and freely chosen. The machine is applicable to end face machining of various grades of metal pipes, such as carbon steel, stainless steel and alloy steel. It is widely applied in heavy type pipe lines of petroleum, chemical natural gas, power supply construction, boiler and nuclear power.

The spud is main part Cutter Suction Dredger, when operation, through steel spud

Cross-cut construction method

1, the cutter suction Dredger is equipped with spud in the general area of construction, steel spud should be symmetrical cross-cut method or a steel cross-car spud digging method of construction.

2, in the area of large waves, equipped with three cable dredger positioning spud should be positioned with three cable cross-cut construction method.

3, the flow velocity in large areas or large waves, equipped with an anchor on the cable cross digging equipment cutter suction dredger, anchor cable should be used cross-cut construction method

Segment dig method

1, Trench length greater than the length of the water pipeline dredge effective extension should be segmented according to the length of the dredgers and the construction of water pipelines can Excavation.

2. Trench turnaround curve is divided into several sections require excavation of straight line segments can be linear piecewise curve approximation safe construction.

3. Trench different specifications or different schedule requirements, should be in accordance with the requirements of the contract segment.

4, navigation or interference by other factors, the construction can be segmented as needed

Shun countercurrent construction

When river construction using steel spud positioned, should adopt the downstream construction; construction should be used when using countercurrent anchor cable cross-dig construction method; when the large flow rates, and can be used under construction downstream end of the anchor to ensure safety.

The specifications of our spud

A. General

High accuracy, fully welded, painted construction can be used for cutter suction dredger.

When the cutter suction dredger is working, two spuds insert the sea alternatively, one is main pile, always aligned pocket centerline and the other is vice pile used forward exchange, to meet dredger back and forth and meet dredging work.

B. Construction and procedure

The construction is to be built according to the drawing with rules of good workmanship and to be built the longitudinal frame system.

The construction is of rolled Steel Pipe sections with varying wall thickness, from40mm to 150mm, which are carefully manufactured and checked to ensure roundness, straightness, segment connection deflection within the specific tolerances.

C. Procedure

Pre-roll bending pf plate-Rolling of cylindrical hull-Welding the vertical seam to close the section-Heat treatment-Rolling to correct ovality-Assemble of the several pipe sections-Assemble with accessories( Sheave , expansion part etc.)

D. Materials

All fabricated steelwork used in the construction of the spud will be to manufacturing standard of classification society BV, GL, LR, DNV

All steel used to be blasted and shop primed both sides. Using DH36 and D690

All materials proposed will be selected to comply with the latest Health and Safety Rules.

Paint systems for hull protection will be of the highest quality (Hempel, Inter, Sigma, Jotun)

E. Welding

All welding will be performed in accordance with drawing and order and UniSite experience and all welding will be continuous and full penetration.

Welding seam preparation, welding method, welding material and consequent preheating temperature acc. to UniSite standards and approved by clients.

UniSite will control preheating, cooling down rate

Weld surface on the outside spud surface are to be grinded flush.

All welding to be examined UT and some to be examined X-ray.

F. Workmanship

The workmanship have good marine practice. Care are taken to ensure fair lines, smooth surfaces and neat welding.
