      TPEP anticorrosive SSAW steel pipe factory

      發布時間:2020-07-08

      3PE anti-corrosion internal fusion bonded epoxy anti-corrosion steel pipe (also known as TPEP anti-corrosion pipeline) is an upgrade product based on the external polyethylene internal fusion bonded epoxy composite steel pipe, which is the most advanced anti-corrosion form of buried long-distance pipeline at present. TPEP anticorrosive SSAW steel pipe factory specification: DN 100-dn 1800 TPEP anticorrosive steel pipe material: Q235B or Q345B, coating thickness: outer wall 2.0-4.0mm, inner wall 0.35-0.5mm, coating method: fusion winding and thermal spraying synchronous one-time film formation. Product length: 12M, or specified, normal pressure: 0.1mpa-5.0mpa Connection mode: welding, joint coating method: stainless steel lining without repair technology, small internal friction coefficient, 0.0081-0.091, conveying the same flow can reduce one caliber level. Application fields: long distance water pipeline, water conservancy industry, water supply industry   The price of TPEP corrosion-resistant SSAW steel pipe factory for municipal drainage - entity manufacturer - 3PE anticorrosive seamless steel pipe is rising rapidly, which not only attracts the attention of the market, but also attracts the attention of the national development and Reform Commission, the Ministry of industry and information technology and the China Steel Association. Recently, the China Steel Association said that the current sharp rise in steel futures prices is not caused by market demand pulling or market supply decreasing. The recent steel price is a kind of speculation. Due to the over interpretation of production reduction expectations, it is not the demand driven price rise. At the same time, affected by the meeting of the China Steel Association, dish washing will be intensified. In the morning of August 11, the main futures contract of rebar in the previous period plummeted by 3% to 3847 yuan / ton. By the end of the day, the main contract 1801 of rebar futures closed at 3862 yuan / ton, down to 3812 yuan / ton, down 2.7%. The main contract of iron ore futures closed at 536 yuan / ton, while the steel price dropped to 527.5 yuan / ton, a decrease of 4.71%. Strengthen 3PE anticorrosive steel pipe structure: one layer is epoxy powder, the second layer is adhesive, the third layer is polyethylene. The three materials are combined with steel pipe to form excellent corrosion ability. The construction method is simple and quick, and the service life can reach 30-50 years. It also has good corrosion resistance and impact resistance at low temperature, and low water absorption of PE. At the same time, it has high epoxy strength, low water absorption of PE and good softness of hot melt adhesive, which has high reliability of anti-corrosion. This kind of anti-corrosion features simple manufacturing process, good anti-corrosion effect and low price, which is generally recognized by the pipeline manufacturing industry. Anticorrosion of three-layer polyethylene (3PE) steel pipe and two-layer polyethylene (2PE) steel pipe for oil and gas use, standard: SY / t0413-2002 and din30670. Yuncheng municipal drainage TPEP anti-corrosion SSAWl steel pipe factory - strengthen 3PE anti-corrosion steel pipe product advantages: compared with ordinary steel pipe in harsh environmental conditions, serious corrosion will occur, so as to reduce the service life of steel pipe anti-corrosion and thermal insulation pipe. The service life is long, which can be used for 30-50 years, and installed correctly However, it can also make the maintenance cost of the pipeline low. The anti-corrosion and thermal insulation pipeline can automatically set up an alarm system to automatically detect the leakage of the pipe network, accurately locate the fault knowledge, and alarm. The heat loss of 3PE anti-corrosion insulation pipe is only 25% of the traditional pipe material. In the long run, it can save a lot of resources and significantly reduce the energy cost. Moreover, it has strong waterproof and corrosion resistance, and can be directly embedded without trench Underground or underwater, the construction is simple and fast, and the comprehensive cost is relatively low. It also has good corrosion resistance and impact resistance under low temperature conditions, and can be directly embedded in the environmental frozen soil. 3PE composition: epoxy powder (FBE > 100um), adhesive (AD) 170 ~ 250um, polyethylene (PE) 1.8 ~ 3.7mm (ordinary ~ reinforced) are fused to form an excellent anti-corrosion coating. Three layer polyethylene anticorrosion (φ 30mm - φ 1020mm) is one of the main technical systems for external corrosion protection of buried pipelines at home and abroad. Product features: 3PE anti-corrosion steel pipe has good anti-corrosion performance, low water absorption and high mechanical strength. In recent years, it has been more and more widely used in buried water, gas and oil pipeline in China
