1. what is HDPE plastics tube/pipe?

HDPE tube/pipe is ethylene and a small amount of other carbon hydrogen combined material copolymer formed HDPE thermoplastic property plastics （ high density polyethylene (PE) ） made formed types flexible plastics tube/pipe. this type of type type plastics tube/pipe tool has stability separation and polymer/macromolecule density, therefore can resistant property chemical product. in addition, it 不会泄漏 or 腐蚀, and in resistant use property and strong/high degree tool has many advantages. 如今, HDPE tube/pipe in full scope/range inner used for certain industry in mixed or tube/pipe.

2. HDPE plastics tube/pipe benefits

2.1 corrosion resistant property

HDPE plastics tube/pipe main/primary used for liquid and gas 体, is it 们不会 by liquid or gas in in chemical material 质腐蚀. and metal tube/pipe different, HDPE plastics tube/pipe 不会腐蚀 or 生锈, therefore 不会发生泄漏 or 堵塞.

2.2 resistant high pressure

HDPE plastics tube/pipe can 够承受 high pressure 而不会 make pipeline deformation or loss bad. therefore, it can 处理生 active use water system and water system unstable water pressure.

2.3 无泄漏接头

and metal pipeline system different, metal pipeline system through machine 械接头连接. HDPE plastics pipeline system can through hot method 连接. this type of methods and will HDPE plastics tube/pipe surface add hot to temperature degree, rear pipeline cooling formed overall, and 无泄漏 tube/pipe 接头.

2.4 延 long use lifespan

HDPE plastics tube/pipe use lifespan ratio metal tube/pipe long （仅持续20至50 year ）. HDPE plastics tube/pipe use lifespan in 50至100 year between, specific 取决于 various application.

2.5 ring good property

HDPE plastics tube/pipe by is for ring effect/influence most small. HDPE plastics tube/pipe production ratio non plastics tube/pipe consumption more less can 源. in addition, HDPE plastics tube/pipe production process in production process in toward gas in 排放危险 毒素.

2.6 cost 效益

manufacturing and processing plastics tube/pipe cost ratio production metal tube/pipe 便宜. in addition, HDPE plastics tube/pipe weight light, therefore ratio metal tube/pipe 节省运输 and cost.

due to HDPE plastics tube/pipe belt/tape benefits, HDPE plastics tube/pipe application used for many field/area, 如商业 and use water, industrial 流体输送, pipeline system, waste water system and gas material supply.

3. HDPE plastics tube/pipe most Common methods.

hot principle is will HDPE tube/pipe add hot to temperature degree, rear through add force will it combined. this type of force make melt pipeline mixed combined in 一起, 导致熔化. melt combined rear 接头完 full 无泄漏. 接头区域 in strong/high degree and pressure features upper and pipeline 本身完 full versus and other.

HDPE plastics tube/pipe has types Common methods, for 接链接, 承插连接, type and electrical 熔链接.

3.1 for 接连接

this is most Common welding HDPE tube/pipe methods. HDPE tube/pipe use for hot for machine add hot to temperature degree. rear it in pressure lower by toward front melt combined in 一起. this type of technology in amount 方面创造 持久 has 效 连接.

六步 for 接链接 methods separation is:

• 清洁, and for pipeline 末端

• 面 toward pipeline 末端以建立平行 surface, 垂直于 in 心线

• tube/pipe for 齐

• add hot pipeline 接口

• through add force will pipeline 两端连接 in 一起

• maintain to cooling

3.2 承插连接

该 technology meanwhile add hot tube/pipe outer surface and pipe fittings inner surface, to it to 一定 熔 combined temperature degree, will tube/pipe 端插入插 base/seat in, will its solid to to cooling. methods usually is will pipeline to tube/pipe 接头, is pipeline to pipeline.

this is 承插连接 generally steps:

• 清洁 tube/pipe and tube/pipe inner surface

• 准备 tube/pipe 端

• add hot parts 直至达 to temperature degree

• 连接 tube/pipe and tube/pipe let it cooling

3.3 鞍 type 连接

鞍 type similar 于承插连接, used for will tube/pipe 接头连接 to pipeline surface. this meanwhile add hot pipeline outer surface and “鞍 base/seat ” type parts surface, to surface 都达 to temperature degree. this can through use is technology design type for machine achieve.

below/following is used for 创建鞍 type 连接接头 六 basic steps:

• 清洁鞍 base/seat parts in pipeline surface

• will type for machine in pipeline upper

• according to 程序排列 pipeline and tube/pipe surface

• add hot pipeline and base/seat parts

• toward lower 推并按住两 部 separation

• cooling 接头并拆 lower type for machine

3.4 electrical 熔链接

this type of HDPE pipeline technology and other hot 熔连接 methods full different. main/primary difference in add hot pipeline or 配 parts surface methods. in positive hot 熔连接 in, add hot machine used for add hot pipeline and parts surface. is electrical 熔接头 through or conductive polymer in internal add hot. electrical through parts in conductive material 时, generate hot amount. rear pipeline by cooling, it viscous in 一起.

实施 electrical 熔连接时 常规 steps is:

• 准备 pipeline and electrical machine

• 标记 pipeline

• for maintain pipeline solid 定

• 施 add electrical 流

• cooling parts 并松开夹 tool
