Applications

It is used for conveying gas,water,and petroleum of both the oil and natural gas industries.

Packaging & Delivery

Each bundles pipes will be bundled with 6-8 pcs steel strips and with shipping marks and 2 nylon strips

40-50 days delivery on china port upon receiving orinigal LC or prepayment.

Q:How do you solder purple copper plate and steel tube?: The copper plate and the steel tube are brazed by brazing or argon arc welding.

Q:How big is the seamless steel tube of DN50?: Domestic steel pipe diameter is generally divided into A series and B series, DN50 pipe diameter of 60mm and 57mm respectively, the wall thickness should be based on your design pressure, temperature, pipe material to calculate.

Q:D108*4 what does "D108" mean by seamless steel tubes? What does "*4" mean?: Seamless steel pipe: a pipe with a hollow cross section, used as a conduit for transporting fluids, such as pipelines for transporting petroleum, natural gas, gas, water, and certain solid materials. Compared withsteel and roundsteelinsolid, flexural torsional strength in the same time, the weight is light, is a kind of economic section steel, widely used in the manufacture of structural parts and mechanical parts, such as the oil pipe, automobile transmission shaft, the bicycle frame and steel construction with scaffold with steel pipe manufacturing ring parts can be improved the utilization rate of materials, simplify the manufacturing process, material saving and working hours, has been widely used to manufacture steel tube.

Q:What's the difference between a cracked carbon steel tube and a liquid carbon steel tube?: Cracking carbon steel pipe higher requirements, the general carbon steel pipe to be normalized, the fluid carbon steel pipe as long as the normal annealing treatment.

Q:What are the uses of seamless steel tubes?: A large number of pipes used for conveying fluids, such as pipelines for transporting petroleum, natural gas, gas, water, and certain solid materials.

Q:What's the gate number of the precision steel pipe?: This kind of steel tube and ordinary hot-rolled seamless steel pipe and cold drawn seamless steel tube in the outer surface is different from the outer surface, and the diameter of the smooth finish of precision steel tube, stainless steel color and the same, inside and outside surface due to manufacturing reasons with a layer of oil.

Q:What is the buckling type thin-wall steel pipe? What is a tight set of thin-walled steel tubes? What's the difference between the two?: The wire pipe thread (box, cup lock fastening points) (JDG) and buckling type (KBG) two. Products are made of high-quality steel pipe, through precise stamping molding, supply pipe and terminal box connection. The nut is hexagonal, and the convex point is punched at the six corner so as to form a good multi-point contact after being connected with the junction box.

Q:What do you mean by "SC" in welded pipe SC200? What's the diameter of 200?: SC in principle, it should be called water gas pipe, also called thick wall steel pipe;

Q:How long is the seamless tube?: Generally finished seamless steel tubes are less than twelve meters, mainly for the convenience of shipment.In times of rolling (processing), the steel pipe can reach 80 meters or longer.

Q:Is hot dipped plastic pipe steel?: Hot dip plastic composite pipes used in coal mine gas drainage, ventilation system, fire water system, central air conditioning HVAC piping circulating water, industrial water supply and drainage, water supply and drainage life, conveying gas and other gases, power threading, chemical pipelines and water disposal pipe etc..

The company's main products are: the low-pressure boiler seamless steel pipe, oil casing seamless pipe, ship seamless steel tubes, seamless steel pipe, petroleum cracking, chemical fertilizer equipment, seamless steel tubes, structural seamless steel pipe, seamless steel hollow pumping rod with eight series. According to GB, ASTM, APL5L, AP15CT, DIH, JIS and other standard production seamless steel tubes.
