Seamless Stainless Steel Structural Tubing Umbilical For Heat Exchanger
Coil technology and specific heat exchanger with stainless steel coil, including outer coil and inner ring coil, described in the outer ring coil body by a stainless steel pipe spiral winding bottom-up, then top-down spiral winding form described in the inner ring coil, described in the outer ring plate of the pipe body and a space between the inner ring coil tube body, described in the outer ring coil tube body and the inner ring coil body piece by inside and outside the circle, evenThe outer coil body and the inner coil body are used for heat transfer at the same time, which has high thermal efficiency and improves the heat transfer effect.Secondly, the use of stainless steel pipe as the coil, effectively improve the oxidation resistance, corrosion resistance, thus prolonging the service life of the coil.In addition, the invention has the advantages of simple structure, reasonable design and firm coil structure.
| Production process: | first cold rolling, then cold drawing and coiling. |
| Surface treatment: | vacuum bright annealing (vacuum bright annealing process, the inner and outer surface of the stainless steel tube will not contact with oxygen, no |
| oxide skin, so that the inner and outer surface of the stainless steel coil is cleaner, brighter and more delicate) | |
| Delivery state: | soft state (HRB≤90) |
| Material of coil: | 304/304L / 321/317L / 2205/2507 |
| Production standard: | ASTM(ASME)SA/A312 / A213 / A269,DIN, GB,JIS. |
| Coil tubing specification: | OD Φ 4mm-x 31.8mm, wall thickness (WT):0.7-2.11mm. |
| Tolerance range: | outside diameter: ±0.1mm, wall thickness: ±10%. |
| Coil length: | |
| 1.1: | According to the difference of outer diameter and wall thickness, the production weight of a seamless coil tubing reaches about 120KG. |
| 1.2: | Please note that the longer the length of seamless coil is, the more difficult it is to produce, and the higher the price will be. |
| 1.3: | the length of the stainless steel coil tubing according to the external diameter and wall thickness of the demand, using the stainless steel pipe theory calculation formula conversion. |
| 1.4: | Solemnly declare: the whole reel seamless coil has no welding point. |
| 1.5: | according to the demand, can also be used with a number of stainless steel seamless coil butt welding into a few thousand meters above the super-long stainless steel coil tubing. |
| Finished product inspection: | hydraulic test (10Mpa - 35Mpa)/ air pressure test/eddy current flaw detection test. |
| Coding identification: | according to customer requirements. |
| Packing method: | using woven bags or plywood boxes, plywood spools, convenient transportation and storage;The finished stainless steel coil will be wrapped into a roll of packing or wrapped in wooden shaft packing, sea, land transportation, air transportation are very convenient, reduce transportation costs and convenient customer inventory storage. |
| Delivery time: | |
| 2.1: | T/T settlement can be settled with KG price and rice price. |
| 2.2: | the production cycle of stainless steel seamless coil with a single roll weight less than 30KG is about 25-30 days. |
| 2.3: | Stainless steel seamless coil tubing single volume weight 30Kg-50Kg production cycle in about 35-45 days. |
| 2.4: | Single roll weight of stainless steel seamless coil tubing is 50Kg-120Kg. The production cycle is about 50-60 days. |
Product advantages:
stainless steel bright coil tubing in use can be cut according to the required length requirements, bending, reduce waste, reduce costs, especially in the transmission pipeline installation to save the installation of joints, improve safety performance.Seamless coils are a good choice to reduce leakage risk in hydraulic systems.In the process of installation, the use of joints is greatly reduced, and the safety of the whole pipeline system is completely improved.Enhance the security of system operation.
Scope of application:
Stainless steel coil tubing is widely used in oil drilling, shipbuilding, aerospace and petrochemical refining equipment, spiral around the pipe heat exchanger, the residual wound tube heat exchanger and cold treatment, chemical industry pipeline, fluid pipe, steam heat preservation pipe, stainless steel heating coil (heating coil pipe), high pressure fluid pipes, stainless steel heat preservation heat insulation pipe line,Anticorrosive stainless steel pipes and cables protected by PVC sheath, umbilical cables and other industries.
We can supply stainless steel coil tubing upon request
