Oil Casing - OCTG – TOP STEEL Detail:

1. Line pipe

1)  Line pipe:out of the ground is to oil,gas or water through a pipeline to transport pipe to the oil and gas industry enterprises;
2) Type:line pipe including seamless pipe and welded pipe;
3) The pipe end form:flat end,threaded end and socket end;
4)  Connection:welded ends,coupling connection,socket links;
5)  Materials:L245, L290, L360, L415, L480, GR.B, X42, X46, X56, X65, X70,X80, X100 etc.;
6)  Size:10.3 – 2032 X 1.7 – 39.7 mm;
7)  Application:For oil and gas industry of oxygen,water and oil pipelines;

2. The tubing

1) After completion of the tubing in drilling oil and gas from the reservoir to the surface of the pipeline transport, mining it to withstand the pressure generated in the process;
2) Ends processing forms: non-upset threaded and coupled;
3) Main brands:J55,K55,N80,L80,P110 etc.;
4) Category:not upset tubing (NU), external upset tubing (EU),the overall joint tubing (IJ);
5) Specification:8 – 1240 X 1 – 200 mm;
6) Application:in the wells used for producing liquid or liquid injection tube;

3. The casing

1) Usually in the basement of the building to protect the pipeline or pipeline installation easy hoops;
2) Classification:rigid casing,flexible waterproof casing,steel casing and metal casing;
3) Main brands:J55,K55,N80,L80,P110 etc.;
4) Specification:8 – 1240 X 1 – 200 mm;
5) Application:for oil well casing and seamless tubing;

4. 2PE/3PE anti-corrosion and single-layer PE anticorrosive

1).3PE anticorrosive:
Three-layer structure of PE pipe corrosion:the first layer of powder epoxy (FBE>100um),the second layer of adhesive ( AD) 170~250um,a third layer of polyethylene (PE) 2.5~3.7mm.Three materials integration,and with the steel firm to form an excellent coating;
2).Diameter range of Φ60~Φ14202).2PE anti-corrosion steel pipe:
PE pipe corrosive story structure,the first layer of adhesive (AD),a second layer of polyethylene (PE),the same as the standard blend of two materials,the thickness of layers with three PE:SY/ T0413-2002 buried steel pipeline polyethylene coating technology standards GB/ T23257-2009 buried steel pipeline polyethylene coating technology standards;
3).Single PE anti-corrosion steel:
single layer PE is the use of anti-corrosion steel curtain coating process ( also known as curtain method), the steel pipe after rotation frequency heating, steel top is fitted with a polyethylene powder container by pouring dusted steel tube surface polyethylene coating;
4).3PE anticorrosive and external single PE anticorrosive performance comparison

performance comparison Outer 3PE FBE epoxy pipe Outer single polyethylene pipe
Sintered outer coating process Wrapped three-layer structure Curtain method, curtain coating, single
Anti-corrosion structure The middle layer is adhesive, outer-storey-density polyethylene Single layer polyethylene, low density polyethylene
Coating thickness 2.5-4mm 1-1.5mm
Adhesion Strong Generally, intolerance boiled
Performance Corrosion resistance, wear resistance Impact general, intolerance scratches
Defect No Easy to pinholes, leveling uneven apperance

5. Coal tar epoxy

1).Composition:
The product is formulated with an epoxy resin,coal tar pitch,anti-rust pigments,additives,modified amine from.Products with rapid drying,good adhesion,flexibility,and easy two-component packaging and construction.With acid,alkali,salt,water,oil etc.;
2).Characteristics and Uses:
①The paint combination of high mechanical strength epoxy resin adhesive force,erosion and chemical resistance characteristics of asphalt water-resistant,anti-microbial,anti-plant roots,is a high performance anti-corrosion insulation coating,the products are Good chemical resistance,water resistance;
②suitable for oil,gas and water pipelines,water,gas,pipelines,refineries,chemical plants,sewage treatment plants and pipeline corrosion of equipment,may be used as antiseptic and mining offshore oil rigs and underwater portion of the ship,corrosion downhole equipment;
3).Coat corrosion:
High-density polyethylene jacket anticorrosive structure:the outer surface of the pipe wrapped high density polyethylene material with high mechanical strength and excellent corrosion resistance,can protect the pipe to avoid the transportation,installation and use of the process due to external factors damage caused.Manufacturing outer casing should be added antioxidants,UV stabilizers,and carbon black.Polyethylene outer tube easy to aging,such as open storage and other objects appropriate to tarp covered dumps should be kept away from heat and ignition sources,made after anti-corrosion steel,prohibit exposure,quenched,or polyethylene outer tube easy to crack,the impact of product performance and service life;
4).The process has been the duty epoxy powder coating using electrostatic spraying.Since epoxy powder Jin Su troubled by adhesion,epoxy powder dip has not been able to promote.Current come with three coconut epoxy powder dip developed special phosphate solution,for the first time to overcome the adherence problem epoxy powder dip process,began to dip epoxy powder of this emerging technology;
5).corrosion standards:
FBE epoxy powder preservative execution SY/T0315-2005<steel pipeline single FBE topcoat technical specifications>
2PE/3PE preservative execution GB/T23257-2009<buried steel pipeline polyethylene outer coating technology standards>
Anticorrosive surface rust criteria:the outer surface of steel pipe sand-blasting by GB/T8923-2008 requirements of Sa2 1/2 grade steel anchor profile of the surface of 40-100μm;
6).Applications:
Anti-corrosion steel base material including spiral,straight seam pipe, seamless pipe, etc., are widely used in our long-distance water,petroleum,chemical,natural gas,heating,sewage treatment,water,bridges,steel,marine water piling pipeline engineering;
7).Advantages:
①improve the life of the steel pipe;
②combination of mechanical strength and plastic pipe corrosion resistance in one;
③outer coating of 2.5mm or more,scratch resistance,bump;
④inner wall of the friction coefficient is small,0.0081-0.091,reduce energy consumption;
⑤the inner walls meet the national health standards;
⑥smooth wall is not easy scaling,self-cleaning function;
