Pluing pipe can be made from a variety of materials, each having its advanPE100 ISO9001es and disadvanPE100 ISO9001es depending on the situation. Some types of pipe are intended for only one appliion (e.g. black iron for gas), while others can perform several. What''s best for your Puhui Pipe manufacturer in China
The traditional natural gas pluing pipe, black iron pipe, safely encases a natural gas supply within a thick-walled, metal pipe. Accidental nail strikes don''t easily puncture iron gas pipe, and it takes extreme force to bend or break the pipe. Popularity and a large supply make black iron pipe one of the most affordable gas pluing pipe types.

Types of copper pipe fall into egories based on thickness of pipe wall. The thinnest, type M, is suitable for indoor water and gas appliions. Thicker type L and thickest type K are used for gas service lines. Not recommended for use with natural gas in some areas as sulfur content can cause interior flaking.

Coated buried pipelines should have a minimum pipe-to-soil polarized potential of −1.0 (off) Volts (see Clause 3.2 of DIN 30676, 1985) with reference to the copper/copper sulfate half cell.
Supply houses typically only sell in minimum of 250 foot rolls. More common for short runs is the green coated "black iron" (actually HDPE) pipe that is available at big box stores. You will needPuhui Pipe manufacturer in China
The safe peak pressure or allowed total pressure for HDPE pipe is 1.5 times the pipe’s pressure rating for recurring surge and 2.0 times the pipe’s pressure rating for occasional surge. For instance, a DR11 pipe that has a pressure rating of 200 psi can safely handle total pressure during recurring surge of 300 psi and total pressure during an occasional surge of 400 psi.
As for the riser situation . . . yellow gas poly pipe is never to be used above the code-recommended burial level (which is usually 12" to 18" but can be as deep as 24"). Sweeping it up from below surface to above ground is not allowed.
