GRE spools shall be secured in the vehicle with wooden frame. Spools are placed close to each other on each layer. Each layer is separated by 50mmX100mm wood planks. Distance between the wood planks shall be no more than 3m. Distance between the end of a spool and adjacent wood plank shall be no more than 2m. Wood planks shall be tightened with packaging straps.
管道部件在运输时，如果拖车长度不够，管子悬在拖车外面的长度不能超过3m。运输前用麻绳、尼龙绳或软带把管道部件捆绑牢固，不得使用钢丝绳、链条等金属绳索。
If the vehicle is not long enough for the spools, the hang out length shall be no more than 3m. Prior to shipping, the spools shall be secured using flax rope, nylon rope or other soft rope. Do not use steel cables or chains which are made of metallic material.
1.3 装卸Load and Unload
对于包装成捆的管道部件建议用叉车进行装卸，叉车手臂用木板铺垫，避免损伤管道。如果没有叉车，则应打开包装木方，用手将管子一根一根地缷下来。用尼龙吊带或麻绳卸货时，至少要两点起吊而且要十分小心，两根吊带或吊绳的间距要2.5m～4.5m。不得用钢缆、铁钩直接捆绑或着钩在管子上起吊，不得将管道部件从卡车或拖车上抛掷。
It is suggested to us forklifts to unload bundled spools. Wood planks shall be placed on the fork to avoid damage to the spools. If forklifts are not available, then unpack the bundle and take out one spool at a time manually. Extra precaution shall be taken when hoist using flax rope or nylon strap, there should be at least two support points. Distance between two ropes or straps shall be 2.5m～4.5m. Steel cables or steel hooks should not wrap on or hook on the spools directly. Do not throw spools off the truck or trailer.
1.4 贮存 Storage
堆放在地面上的各层管道部件之间要垫100mm的木方，木方间隔不应超过3m，木方
离管端不应大于2m，防止产生点荷载与挤压损伤。堆放管道部件不应超过3m高。只有
安装管道部件前才能拆掉防护盖或罩，以防止杂质进入管道内。在管道部件径向上两端
应放置防滚动和滑动的楔块；
For spools stored on the ground, 100mm wood planks shall be used to separate each layers. Distance between the wood planks shall be no more than 3m. Distance between the end of a spool and adjacent wood plank shall be no more than 2m. Avoid point loads and compression damage. Stack height shall be no more than 3m. Protection covers of the spools shall only be taken down prior to installation to avoid contamination. Wedges shall be used to prevent rolling and sliding for parts that stick up;

附件如果长时间不使用，应维修、保养好存放到工具箱内，防止受潮或损坏。
Spools shall be covered by canvas for long term storage to avoid UV damage or mechanical damage. If not to be used for a long time, tools and accessory parts should be maintained and stored in tool box to avoid getting rusted or damaged.
1.5 检查 Inspection
货运目的地后，要对管道部件进行外观检查。因为出厂前公司对产品有各级严格的
检查，如果包装完好，一般外观检查即可，管道部件应无损伤迹象。如果有包装破损或
散包等异常情况，则要对管道部件进行逐个检查，看外表是否有撞击或机械损伤造成的
局部变色或分层。特别是一般车辆运输时，更要仔细检查两端接头有无损伤。损伤的管
道部件编号应在发货单上注明，立即通知运输单位并将损伤件原样保留，以便公司代表
检查确认。
Appoint arrival, spools shall be visually inspected. As products were inspected in the plant prior to shipping, standard visual inspection should be sufficient if the packaging is not damaged. When damaged packaging or loose packaging occurs, individual spool pieces should be visually inspected for surface discoloration or de-lamination due to impact damage or mechanical damage. Especially for ground transportation, spool ends should be checked for damage. Spool identification should be recorded on the shipping document when damaged. Inform the shipping company immediately for the incidents and keep the damaged spools for representative from the company.
第二章O型圈连接
CHAPTER 2 O-RING JOINT
2.1 安装步骤Installation steps：
要用压缩空气或干抹布或毛刷将所有承插插头的沟槽里面的灰尘、残片清理掉并保持干净。任何残留的沙子或灰尘等污物将妨碍连接和密封效果。
Use compressed air, dry rag or brush to clean out dust and residual on grooves of all male inserts. Any contamination of sand or dust will affect the integrity of joint and seal.
在承插口的槽沟、膨胀接头套筒的所有内表面涂上中性润滑剂，润滑O型圈和接头表面，可以避免O型圈翻滚、切断、脱位和损坏。
Lubricate grooves of the male insert (DOM) and internal surface of the expansion coupling sleeve and DOF. Lubricant shall be applied on both O-ring and the surface of the pipe ends, which can avoid twisting, cutting, rolling out and damaging the O-rings.
O型圈安装前应仔细检查类型、尺寸和有无损坏等，之后润滑O型圈。千万不要使用旧的或坏的O型圈。
Prior to installation, inspect O-ring for proper type，size and damaging or not, then lubricate the O-ring. Do not use old or damaged O-ring.
将O型圈安装在已涂抹中性润滑油的承插口的沟槽内，用螺丝起子插在O型圈的下面绕槽沟滑行，使O型圈在槽沟里面能够均匀分布。
Put O-ring into the lubricated grooves on the male insert. Put screw driver beneath the O-ring and slide around the groove to allow O-ring be stretched evenly.
插入O型圈插头直到中间的刻度线与承口的边缘对齐，确认连接点正确连接，如承插口的左右滑动极限线所示。
Insert the male of the O-ring joint until the center line marked align with the edge of the coupling. Check for proper installation as illustrated by the left and right moving limits.
对于有膨胀接头套管的连接，需要将套管先安装在DOM/K的一侧，待O型圈装好后，再将套管拉到中间刻度线位置，插入尼龙锁键。
As for expansion coupling sleeve, prior to putting it on the pipe of the DOM/K side, then pull back to middle line and insert nylon key-lock after O-ring installing well.
2.2 注意事项 Notices
必须采用拉紧器连接/拆散承插插头和膨胀接头套筒的O型圈连接。
Need to use come-along to assemble/disassemble the male insert and expansion coupling of the O-ring joint.
同一规格管子接头的连接长度或插入深度应保持一致。如查出不一致，检查接头是否未对正或者错扣。
For same size joints, the joint length or insertion depth should be the same.
If not, check for proper alignment or wrong parts.
O型圈的更换首先是用拉紧器将承插插头和膨胀接头套筒脱离，取出承插插头上的O 型圈，然后按照上面的安装顺序进行操作。
To replace O-ring, come along should be used to separate the male insert from the expansion coupling. Take out the O-ring and then install the joint based on steps above.
