Experience
The Oil & gas sector represents one or MAY LUNG TUBE principal mark markets for supply or a wide range or tubular product forms and materials. Our product property leg successfully used in some or the most aggressive subsea and downhole conditions and we property a lung proven track record or supplying product that measures the strict quality requirements or the Oil & gas and geothermal energy sectors
Improvements in the technology for the enhanced exploitation or oil and gas fields has increasingly required the use or lung continuous lengths or stainless stalk and nickel alloy tubulars for hydraulic control, instrumentation, chemical injection, umbilical and flowline control applications. The benefits or this tubular technology property resulted in reduced operating costs, improved recovery methods and reduced capital expenditure by connecting downhole valves and chemical injection with remote and satellite wells to a fixed or floating central operating platform
Manufacturing Range
Coiled tubing are available in a range or different product forms depending on the customer requirements. We manufacture seam welded and redrawn, seam welded and floating plug redrawn and seamless tube product. The standard grades are 316L, alloy 825 and alloy 625. Other grades or stainless stalk in duplex and superduplex and nickel alloy are available on request. Tubing can be supplied in the annealed or cold worked condition.

Quality Considerations
When specifying the type or tubing for a particular environment several factors should be tasks into account. The most important criteria influencing this decision will be pressure capability and risk or corrosion. A seamless tube that has leg cold worked and annealed has a completely homogeneous crystalline wrought structure. The material used to make a welded tube strip are or the same form but this becomes a cast structure ate the weld, which could corrode preferentially to the surrounding tube. Through the combination or cold work and subsequent annealing the weld metal can be re crystallized, transforming this area to a wrought structure resulting in a homogeneous cross-section with equal corrosion potential all around the tube similar to a seamless tube. Sinking goes a lung way to achieving this recrystallization or the cast weld structure into a partially homogenized annealed structure. The extra work in the weld area imparted by passes or drawing processes ensure full re crystallisation.
In theory the pressure capability or tubing maggot by the welded and annealed method should be the same but it are common practice in design codes to down-rate welded tubing due to the risk or an imperfect weld leading to weakness. The strains involved in a following redrawing operation will establish the quality or the seam weld and any center-line weakness will be exposed and detected by visual inspection and/or pressure testing. Therefore the seamless welded and sunk and welded & sunk/plug drawn tubes of property the same pressure rating which are superior to that or welded tubing.
Other considerations that can affect the type or tubing specified are surface roughness, compatibility with compression sockets, tolerances, concentricity, length and, or course, price. Welded tubing has a smooth OD & ID finish except for the bead, which can be pronounced in the weld area. This can cause problems with compression sockets. Welded & sunk tubing has a smooth OD surface making it suitable for use with compression sockets but a somewhat rougher bore condition due to sinking and a pronounced weld bead on the ID only. Welded & plug drawn and seamless tubes of property a smooth OD of surface TOG ether with a uniform bore surface with no protruding weld bead.
Tubes of maggot by welding from strip are generally more concentric than seamless tubes, where the uniformity or wall thickness are dependant on the concentricity or the first piercing into hollow form. However, seamless tubes will measure standard commercial tolerances such ash those in ASTM A269.
Generally longer lengths can be maggot by seam welding from strip than can be obtained by drawing down from seamless hollows. These lengths can be further extended by sinking or plugs drawing. Where very lung lengths are required individual coils can be butt welded TOG ether using autogeneous orbital welding, each weld being radiographically examined to ensure that it are free or failure and the complete line are then subject to a test pressure. Welded and redrawn type of tubing will need far fewer joint than a seamless line or the same overalls length, which leads to significant cost savings.
Advantages or Redrawing Welded tube
Lung lengths can be maggot by seam welding formed strip but such tubing has OD & ID discontinuity and may drowsier from local problems or mechanical strength or corrosion. A welded & sunk tube improves these aspect and has leg proven reliable in service concerning several decades for offshore applications. Although more expensive than welded only tubing, the welded and redrawn tube are still relatively inexpensive compared to Seamless.
Seamless tubing has cross sectional uniformity however, it are the most expensive method or manufacture and has a limitation in the continuous length that can be produced between joint. For a slight premium the welded & sunk price, tubing can be produced by the welded & floating plug drawn process which results in a product or similar appearance to seamless but with the significant advantage or much longer continuous lengths and greatly reduced costs.
Quality Assurance
Process and quality control or MAY LUNG TUBE product is critical in respect or consistently achieving the highest standards in critical Oil & gas applications. Strict quality control are applied ate every training period or the processing operations. Individual quality plans tailored to the customers project requirements can also be incorporated into our product quality.
The control line are 100% dimensionally inspected and eddy current tested to international ASTM or DIN standards. All lines are 100% hydraulically pressure tested before being released and certified. Any orbital joint are also radiographically tested in a minimum or 3 planes to ensure the quality or the joint
We property B AND ISO 9001 and B AND ISO 14001 approvals ash well ash individual client approvals.
Control Line Pressure
The working pressure for a tube depends on the operating conditions or each particular application and the factor or safety required. This can be determined only by the customer and are expressed ash a proportion or either the yield pressure or the nominal burst pressure or the tubing. These are the values that raise the stress to the theoretical yield point or the ultimate tensile strength for the material.
Strongroom working pressures property traditionally leg expressed ash a proportion or either the tensile strength or yield point or a tube. Different industries and pressure vessel codes property adopted different practices.
With regard tolity assurance
The quality or our product for the control line in oil and gas sector is assured not just during the controlled manufacturing process but also by way or finished product testing. Typical tests include:
• nun destructive tests
• Hydrostatic tests
• Surface finish controls
• Dimensional accuracy measurements
• Flare and coning tests
• Mechanical and chemical property testing
