3PP pipe

on
3PP anticorrosive steel pipe is a steel pipe polypropylene anticorrosive coating, which is characterized by good heat resistance.

It is widely used in coating for all kinds of major pipeline engineering.

Most of the large pipeline anti-corrosion in China is 3PE coating, and 3PP and 3PE coating belong to the multi-layer coating system, which consists of the bottom epoxy powder, the intermediate layer binder and the outer PP jacket. The performance of PP is similar to that of PE, and 3PP coating is fully capable of producing 3PP coating with 3PE production line, and no special 3PP coating operation line is required. However, the difference in performance of PP and PE materials, and the performance of 3PP and 3PE coating, can be applied to different environments. The advantages of 3PP coating on certain properties make it possible to play a role in areas where 3PE coatings are not available, so there are many pipeline projects abroad that use 3PP anti-corrosion coatings. At present, it is mainly foreign products that are related to the environment, for some countries with high environmental temperature, and PP is harder than PE, so as to avoid scratch coating.

3PP preservation:

PP three-tier structure of anti-corrosion pipeline: the first layer of epoxy powder (FBE50 - 100um), the second adhesive (AD) 250 - 400um, the third layer of polypropylene (PP) 1.4 - 4.0mm. Three of the integration, and steel pipe with a good solid coating, Coating temperature up to 110 degrees.

Diameter of Φ159 - Φ1220

ASTM A335 Chrome Moly Pipe

Chrome Moly Pipe has become a standard in the power generation industry and the petrochemical industry, not only because of its tensile strength, corrosion resistance and high-temperature strength, but also because of its cost-effectiveness. Grades P-11, P-22 – P-91 & P-92 are prevalent grades for the power industry, while P-5 & P-9 are the grades utilized in major refinery processing.

Steel pipe world standards

Pipe manufacturing refers to how the individual pieces of pipe are made in a pipe mill; it does not refer to how the pieces are connected in the field to form a continuous pipeline. Each piece of pipe produced by a pipe mill is called a joint or a length (regardless of its measured length). In some cases, pipe is shipped to the pipeline construction site as “double joints”, where two pieces of pipe are pre-welded together to save time. Most of the pipe used for oil and gas pipelines is seamless or longitudinally welded, although spirally welded pipe is common for larger diameters. 1.

Orifice Flanges

Orifice flange for run installation should be so constructed, machined and attached to the that the inner surface of the passage extends through the orifice flange so that there is no recess at the orifice plate. Orifice flanges are used instead of the standard pipe flanges when orifice plate or flow nozzle is used. The basic purpose for this is to measuring the flow rate of either gases or liquids in the respective pipeline. These flanges are used in various industrial applications and are available in various sizes and materials.
